CoStar Alternatives for CRE Firms: 8 Options, Priced

One vendor in this category publishes a real, checkable price on its own website. Everyone else is quote-only, including CoStar. We label each figure VERIFIED when it was read off the vendor's own page on August 27, 2026, REPORTED when a named third party published it and the vendor has not confirmed it, and ASSUMPTION when it is our own modelling input rather than anybody's published number. Where two sources disagree we print both rather than averaging them into one figure that describes no real buyer, and where a claim could not be traced to its source we say we dropped it.

Two CoStar numbers, two different buyers

The $40,000 and the $15,130 look like a contradiction and are not one. PriceLevel's $40,000 is a single buyer-submitted contract for the full Suite All Markets tier covering three users with national coverage. Vendr's $15,130 is an average across a small pool that it describes as more than three purchasers and three completed deals, and its own stated $3,000 to $23,000 range is consistent with narrower single market licences rather than All Markets. They describe different products bought by different firms. We are printing both, labelled, rather than blending them into a single average that would describe nobody. The rest of this page anchors on $40,000, because that is the buyer who can plausibly write a $45,000 cheque, and because it is the figure a Suite contract holder can hold up in a renewal conversation.

What a CoStar Suite contract costs over five years

Take the reported $40,000 base, apply the stated 5 percent annual increase, and add nothing else, no implementation, no admin time, no add-on modules. This is a deliberately conservative model that understates your real spend.

The build column is a $45,000 one time fee paid at year zero plus $6,750 a year of maintenance, which is the 15 percent assumption applied to $45,000 and held flat with no compounding. At the end of year one the subscription is still the cheaper path by $11,750. At the end of year two the positions have swapped and the subscription is $23,500 ahead. By year five the difference is $142,275.25 and it widens every year after that, because one line has a slope and the other is nearly flat.

The honest counterweight sits in the same table. A build at the top of our range, $180,000, costs $261,000 over three years with the same maintenance assumption, which is more than double the $126,100 CoStar figure over the same period, and it does not catch up inside five years. If someone tells you a custom build always wins on cost, they have not run this arithmetic. The build only wins when the scope is genuinely proportionate to the spend it replaces, which is exactly what the diagnosis call is for.

Cumulative spend for the reference buyer, five years out. CoStar Suite All Markets at the reported $40,000 median with a 5 percent annual increase as a stated assumption, against a $45,000 commissioned build paid once at year zero with 15 percent a year maintenance. Every figure in the chart is a row from the table above.

The lines cross about four months into year two, at roughly $54,000 of cumulative spend on each path. Before that point the subscription is genuinely cheaper and the build is the worse financial decision, which is exactly what you would expect and exactly what a vendor chart hides by starting the axis somewhere convenient. Year two is the first year end at which the CoStar cumulative, $82,000, sits above the build cumulative, $58,500. After that the gap only opens.

Change either input and the picture changes honestly. At the smaller buyer profile, the $15,130 average from Vendr with the same 5 percent assumption, cumulative CoStar spend is $15,130, $31,016.50, $47,697.33, $65,212.19 and $83,602.80 across the five years, and it does not pass the $78,750 build line until year five. A firm at that spend level should not commission a build on cost grounds, and the honesty section further down says so in more detail. Raise the build to $180,000 and the crossover disappears from the five year window entirely at either spend level. Run your own figures below.

Every default below is a figure from the table above, and every one is editable, because the defaults describe a market and your invoice is a fact. Nothing is submitted anywhere. There is no email gate, no external request and no stored value. The arithmetic runs in your browser and stops there. If your inputs make the build lose, the tool says so rather than quietly hiding the result.

Two notes on the roster before the list. First, LoopNet is not on it. LoopNet is a CoStar Group brand, acquired in 2012, and presenting the incumbent's own marketplace as an alternative to the incumbent would be theatre. Second, several of the most visible CoStar alternatives guides available online are published by companies that sell a competing product and include themselves in their own comparison. That does not make those guides worthless, it makes them worth reading with the authorship in mind, and it is the reason this page states our own commercial interest openly rather than pretending to be disinterested.

1. Reonomy

What it is. An owner discovery and off-market prospecting platform built on public records: deed, mortgage, tax and lien data across the US.

Price. VERIFIED from reonomy.com pricing on August 27, 2026. From $500 per month billed monthly, or from $400 per month billed annually, which the page describes as a 30 percent saving. Export add-ons are listed at $75 a month per one thousand exports.

Best for. Investment sales brokers, lenders and acquisitions teams whose job is finding owners and off-market deals rather than pulling licensed lease comps.

Where it falls short. Its data comes overwhelmingly from public sources, which means commercial lease comps are not part of the product. That characterisation comes from CompStak's own published comparison, which is a competing data vendor, so weigh it accordingly, but it matches what the product describes itself as doing.

Verdict. The strongest affordable owner discovery layer on this list, and the only alternative here with a price you can read in ten seconds. Not a comps or listings replacement.

2. CompStak, Exchange and CompStak One

What it is. Analyst reviewed lease and sale comps contributed by a community of brokers and appraisers, plus a paid tier adding leasing, sales, CMBS and analytics.

Price. The Exchange tier is free in exchange for contributing your own closed deal comps. CompStak One is quote-only with value based pricing, which is REPORTED from research.com and trustradius.com rather than read off CompStak's own page, and the reported description is that prospects discuss their needs on a sales call before receiving a quote.

Best for. Brokers and appraisers willing to trade their own transaction data for access, and firms that need comps depth without a national data subscription.

Where it falls short. The free tier is not free, it is barter, and firms with proprietary deal flow they would rather not publish will feel that. The paid tier has no public price. And CompStak is a data vendor, not a workflow layer, so it changes where your comps come from and nothing about how your firm operates.

Verdict. The closest thing on this list to a direct comps competitor, on a contribution model that some CoStar buyers will not accept.

3. Crexi Intelligence

What it is. A paid data and analytics tier layered on the Crexi marketplace, where the listing side is free.

Price. No public figure. VERIFIED by absence: crexi.com's own pricing page returned HTTP 403 to a direct read on August 27, 2026, and a CRE Daily review states that pricing for all paid plans is available upon request.

Best for. Brokers already using Crexi's free marketplace for listing exposure who would rather add market data in a platform their team is already inside.

Where it falls short. You cannot comparison shop it without a sales call, which is the exact friction that sent you looking for CoStar alternatives in the first place.

Verdict. Convenient if you are already on Crexi. Not a transparency win over the incumbent.

4. CommercialEdge

What it is. A free commercial listing syndication network with a paid Edge Research data tier attached. Part of the Yardi family of products.

Price. Edge Research is REPORTED at $250 a month or $2,400 a year by selecthub.com and trustradius.com; the listing network is free. Those figures are not published by the vendor on a page we could read this week, so treat them as reported.

Best for. Teams that mainly need listing exposure and a modest research tier, and firms already inside the Yardi ecosystem where the integration story is simpler.

Where it falls short. The research breadth is much narrower than a national comps and analytics database. If you are replacing CoStar Suite with this, you are not replacing it, you are downgrading deliberately, which is a legitimate choice but should be a conscious one.

Verdict. The cheapest reported paid tier in this roundup by a wide margin, with a correspondingly smaller dataset. If the firm's related question is property management software rather than market data, our Yardi alternatives page covers that side of the same house.

5. MSCI Real Capital Analytics

What it is. Institutional transaction and investment volume data, now part of MSCI Real Assets, tracking large scale deal flow and pricing trends.

Price. Quote-only, enterprise and value based. REPORTED from msci.com's own product materials as read through search this week: prospective subscribers take a sales call and a demo before a pricing structure is proposed.

Best for. Institutional investors, lenders and research teams whose question is where capital is moving rather than what the third floor leased for.

Where it falls short. It is built for institutional research, not brokerage workflow, and there is no small firm entry point. It belongs on this list because hiding the expensive options would make this an advertisement, not because it saves anybody money.

Verdict. A real institutional grade alternative for one of CoStar's use cases. Not a seat for seat swap for a brokerage.

6. Trepp

What it is. Structured finance and CMBS data covering securitized and non securitized commercial mortgages, loan portfolios and nationwide mortgage statistics.

Price. Quote-only. VERIFIED by absence through G2's pricing page for Trepp Asset Manager, which states that the vendor has not provided pricing information for the product.

Best for. Debt side analysts, CMBS investors and lenders monitoring loan and property level credit performance.

Where it falls short. It is a specialist debt data tool rather than a general listings and comps platform, and its pricing is entirely opaque.

Verdict. Excellent inside its niche, irrelevant outside it.

7. ARGUS Enterprise

What it is. Valuation, underwriting and asset level cash flow modeling from Altus Group, now sold within the ARGUS Intelligence Platform.

Price. REPORTED and weakly. Reseller listings and a Wall Street Oasis forum thread put it near $1,500 per user per month, roughly $18,000 per user a year, with a one time implementation of $5,000 to $25,000 and volume discounts above five seats. Altus Group publishes no pricing of its own, so this is the least firm number on the page and we are flagging it as such rather than quietly averaging it into anything.

Best for. Teams whose real dependency is deal level valuation and underwriting models rather than market wide comps.

Where it falls short. It solves a genuinely different problem. Buying it instead of CoStar would leave you without market data; buying it in addition adds a per seat cost that on the reported figure is the largest per user number in this roundup.

Verdict. A complement to a data subscription, not a replacement for one.

8. MotionCRE

What it is. A commercial real estate deal tracking and pipeline CRM. A workflow product, not a data source.

Price. REPORTED at $249 to $699 a month across its Team, Plus and Power tiers, taken from MotionCRE's own resources page; its dedicated pricing page loaded a sign in screen rather than numbers when we looked on August 27, 2026.

Best for. Brokerage teams who want a modern deal pipeline and reporting layer running alongside whatever data source they keep.

Where it falls short. It does not replace CoStar's core function and does not claim to. It is also the publisher of one of the most visible CoStar alternatives guides on the internet while selling a competing product inside that same article, which is worth knowing when you read it.

Verdict. A credible off the shelf version of the workflow layer, which makes it the honest first thing to price before commissioning one. If a packaged product covers your pipeline properly, buy the packaged product.

9. A commissioned build you own

What it is. Not a replacement for CoStar Suite. A custom system built for the workflow no data vendor covers, sitting on top of whichever data subscription you keep, owned by the firm at handoff. In practice that means a deal pipeline that matches how your team actually stages a transaction, rent roll and offering memorandum normalisation, underwriting handoffs that stop being spreadsheets emailed around, investor and lender reporting assembled automatically, and commission splits that reconcile.

Price. A fixed fee of $45,000 to $180,000, set after a free 45-minute diagnosis call once the integration depth is named, paid in two instalments at build start and at handoff. The firm owns the code, prompts, models and pipeline at handoff and runs it in its own cloud tenant.

Best for. Firms carrying a Suite scale contract with a named workflow that consumes analyst hours every week, and firms that can cut seat count once the internal system stops requiring everyone to have a login.

Where it falls short. It is a bigger single cheque, it needs tighter scope than buying software does, and at the top of our range it loses the cost argument outright against every scenario on this page. It also does not create comps data, so if the goal is to stop paying CoStar entirely, this is not that.

Verdict. The option none of the eight above will show you, and the only one where the bill stops going up.

Each of these is either arithmetic you can check on this page or a structural fact about the two models. Where an argument does not honestly apply to your firm, the next section says so plainly.

One. The math, restated. A subscription never ends. At the reported $40,000 Suite figure with a 5 percent stated increase, five years is $221,025.25 and year six starts from zero progress. A $45,000 build with 15 percent maintenance is $78,750 over the same five years. The lines cross about four months into year two at roughly $54,000 each, and after that the gap widens every single year because one curve has a slope and the other is nearly flat. That is the whole argument, which is why the chart is above the sales copy rather than inside it.

Two. Seat based pricing taxes the team you are trying to grow. The reference contract is one licence covering three users. Every analyst, associate and new hire who needs a login raises the bill, and it raises it on a schedule set by someone outside your firm. An owned internal system has no marginal seat cost at all, so the hiring decision stops carrying a software decision inside it, and the licensed data seats can be concentrated on the people who genuinely need to query the database rather than issued to everyone who needs to see a report.

Three. Asset versus expense. A subscription is rent and it leaves nothing behind. A commissioned system is a piece of the firm: transferable, valuable in a merger or succession conversation, and on the balance sheet rather than only on the expense line. For principals thinking about a five to ten year horizon, or about what the firm is worth to a buyer, that difference is not cosmetic.

Four. Built around your workflow, not the median firm's. Every product in the roundup above is calibrated against the average customer in its category, so you pay for the whole bundle and adapt your process to the fraction of it your firm actually uses. A commissioned system starts from your deal stages, your underwriting standards, your reporting calendar and your commission structure. Nobody has to be retrained into somebody else's assumptions about how a deal progresses.

Five. AI at the core rather than as a line item you cannot benchmark. Across this category, capability arrives as an unpriced uplift discussed on a call. CoStar publishes no pricing at all, so there is no published rate for anything it adds. Crexi's paid tier, CompStak One, MSCI Real Capital Analytics and Trepp are all quote-only as well. That means every capability you add is priced against you rather than against a rate card. In a commissioned build there is no separate licence for the intelligence layer, because the intelligence is the system, and adding a user costs nothing.

Six. Unlimited seats. Analysts, associates, back office, seasonal help, and where appropriate investors and lenders reading their own reports. Zero marginal cost per person changes the question from who needs a licence to who needs access, which is a better question and usually produces a smaller data subscription rather than a bigger one.

Seven. Data ownership and no exit ransom on the part you own. Your pipeline, your underwriting history, your reporting logic, in your own cloud tenant, under an agreement you wrote. Compare that with the exit mechanics in the migration section below, where written notice periods, no mid term cancellation and non refundable fees are the reported norm. Owning the layer removes the negotiation from leaving it, even while the licensed data underneath stays a subscription.

Eight. Vendor risk you stop carrying on the workflow layer. Consolidation is normal in this category and it is visible from outside: CoStar Group acquired LoopNet in 2012 and still operates it as a brand, Yardi acquired PropertyShark in 2010, and Real Capital Analytics now sits inside MSCI. Products get bought, repositioned and repriced on the acquirer's schedule rather than yours. A system your firm owns does not get sunset by anybody, and the roadmap for it is a conversation inside your own office.

Nine. Change speed. A change request to your own system is a scoping conversation and a deployment. A change request to a data vendor is a feature request in a queue behind every other customer's, with no committed date and no obligation. When the thing that needs to change is the thing that makes your firm different from the brokerage down the street, the queue is not an acceptable answer.

What we can actually prove

A list of arguments is worth exactly as much as the evidence behind the firm making it, so here is ours, with nothing rounded up and nothing borrowed. Jim Glaser Law is our nameable reference and the principal takes reference calls. The LELF platform is the fullest example of what commissioning looks like at operating scale: a 47-attorney litigation firm runs its matter, invoice and trust operation on it, holding 13,296 matters, 4,396 clients and 5,684 invoices, with trust reconciled byte identical against the system it replaced. That firm is under confidentiality and stays anonymised, which is why we name the platform and not the firm. Across our practice we have handled more than 6,000 AI calls and delivered more than forty commissions.

Read that honestly and note what it is not. It is not a commercial real estate reference, because we do not have one yet, and we are not going to manufacture one for a comparison page. What that evidence supports is a specific claim: we build systems that carry real operational volume, hold real financial data, and reconcile under audit. What it does not support is any claim that we have replaced a CoStar subscription for anybody, because we have not, and the migration section below says so in plain language rather than around it.

Five situations where every argument in the previous section fails, and where we would tell you to stay put on a call.

Firms whose real dependency is the database itself. This is the big one and it deserves the top of the list. CoStar's value is a proprietary comps, listings and market dataset assembled over decades by people who go and collect it. No custom build creates that. No vendor in the roundup above fully replaces it either; each covers a narrower slice, whether that is public ownership records, contributed comps, debt data or institutional transaction volume. If your firm's daily dependency is the licensed data, keep it, and read the rest of this page as a case for building the layer above it rather than for cancelling anything.

Firms spending roughly $15,000 to $20,000 a year. That is Vendr's average tier, and the arithmetic is against a build. At $15,130 a year with the same 5 percent assumption, cumulative spend reaches $83,602.80 at year five against $78,750 for the cheapest build we scope, so the crossover does not arrive until the fifth year. If the firm is not certain it will operate on the same footing for five more years, or if the $45,000 entry fee is a stretch on cash flow, staying on the subscription is the math backed answer rather than the polite one.

Firms that need something working next month. A subscription starts the day the contract is signed. A commissioned build has a scoping call, a scope, a build, and a parallel run before anybody trusts it. If the deadline is real and near, buying beats building and it is not close.

Solo brokers and small teams. If you are on an entry level plan at the low end of the reported range, at $3,000 a year the subscription is a rounding error against a producer's revenue and a $45,000 build is disproportionate to the problem. The right move at that scale is better spreadsheet discipline and a cheap CRM, not a commission.

Firms with nobody to own the system internally. An owned build needs one named person who cares about it, even at a light touch. Firms without that person are better off renting, because the alternative is an orphaned internal system that decays quietly and then has to be replaced by a subscription anyway, at which point you have paid twice.

1. Is the thing you rely on CoStar for the licensed data itself? If yes, do not cancel. Keep the data and move to question two, which is about how many people need to touch it directly. If no, meaning you mainly use it as a starting point for work that happens elsewhere, continue.

2. Do you know your actual annual figure and your cancellation window date? If no, stop and go find the agreement. Every decision after this one depends on both, and the reported notice periods on this page are a substitute for your own paperwork, not a replacement for it. If yes, continue.

3. Run your number in the calculator above. Is your five year CoStar total below about $80,000? If yes, stop. The cheapest build we scope costs $78,750 over five years with maintenance, so no build we would quote beats your subscription on cost inside that window. Take the $40,000 median against a $71,000 list into your renewal conversation instead and spend the energy there. If no, continue.

4. Is the expensive part of your week a data problem or a workflow problem? If it is data, meaning coverage gaps, missing comps or a market you cannot see, then a different or additional data source is the answer and the roundup above is where to look. Stop here and go price Reonomy, CompStak and CommercialEdge. If it is workflow, continue.

5. Can you name that workflow in one sentence, with a rough hours or dollars figure attached? If no, stop, and spend two weeks measuring before anyone spends money. An unnamed constraint is the most reliable predictor of a build that disappoints. If yes, continue.

6. Have you priced the packaged version first? MotionCRE and the CRM layer inside CommercialEdge are real products at a fraction of a build. If one of them covers your named workflow properly, buy it, and we will tell you the same thing on a call. If they genuinely do not, and the budget runway for a $45,000 to $180,000 fixed fee is real this quarter, that call is the next step.

Almost nobody writing about CoStar alternatives answers this, which is odd, because it is the question that decides whether a firm ever acts on any of the rest. Here is the honest shape of it, with the parts we could source labelled and the parts we could not left out rather than filled in.

First, find your window, because it is not always the date you assume. Third party summaries of CoStar's own agreement language describe written cancellation notice of 30 days for general subscriptions and 60 days for CoStar Real Estate Manager, no mid term cancellation, and fees non refundable once paid. That is REPORTED from joinchargeback.com and subscribed.fyi, not read off a live contract, and your signed agreement is the only document that governs. The reason this is step one rather than step three is a verified review on Trustpilot describing an auto-renewal that landed just past the close of the reviewer's cancellation window, at a higher rate. A second reviewer's advice, in their own words, is to put in a cancellation request as soon as you start a contract. Whatever you think of that as strategy, it tells you that the window is the thing that bites.

Second, export your own work product before access ends. CoStar's product help documentation describes an export path for what it calls My Data, the lease comps and records you created, modified or own inside the platform, out to Excel or CSV. Use it, and use it early enough that you can check what came out. Be clear about the boundary, because it is the whole point of this page: that path exports your work, not the licensed database. CoStar's proprietary comps and listings are licensed for use inside the platform and are not yours to extract in bulk. Third party tools exist specifically to help appraisers pull individual property and comp records into their own workpapers one workflow at a time, which tells you what the practical throughput of this looks like.

Third, run in parallel for at least one full cycle. Nothing gets switched off until the replacement has survived a real reporting period with real deals moving through it. Gaps in a data migration do not surface when you look for them, they surface when a principal needs a 2021 comp on a Thursday afternoon during a negotiation. A firm that skips the parallel run to save six weeks usually spends the saving twice.

We are not printing a total timeline, and here is why. The notice window is sourced at 30 to 60 days. Everything after that depends on the scope of what you are replacing, and we could not find a single credible published figure for how long a CoStar migration takes at any firm size. So rather than invent a comfortable range, we are telling you the honest components: your notice period, plus your export, plus at least one full parallel cycle, plus whatever a scoped build actually takes, which is a proposal stage question rather than a web page question.

The option most firms do not consider. You do not have to leave to fix the problem, and in most of the cases this page is written for, leaving is the wrong move. The data subscription stays. What changes is how many people need a seat on it, and what happens to the data once it is out of the platform. Build the pipeline, the underwriting handoffs and the reporting layer, own them, and let CoStar do the one thing nobody else can do. That path has no cancellation letter, no parallel run and no exposure to a coverage gap you discover in month three.

If your firm's spend sits on the property management and accounting side rather than the market data side, Yardi alternatives and RealPage alternatives run this same sourced cost model on those two platforms, including the seat count question that usually matters more than the switching question. For the underlying decision rather than the vendor comparison, renting software versus owning it lays out the two economic models side by side, and generic SaaS against a custom commission covers when a packaged product is genuinely the right purchase. If you want to know how our fee gets set before you spend 45 minutes on a call, the pricing page shows the mechanics and the process page shows what the weeks actually contain. The full comparison library holds the rest of these, and the industries overview is the short version of who we build for.
