Pick CompStak if your team needs a large, verified database of lease and sale comps to search, export or feed into its own models. Pick Titleman if you want to start from an address and get back a finished comp set, value opinion or underwriting with every figure traced to its source or formula.
Published by Titleman, which makes one of the tools compared. Updated 19 October 2026.
CompStak, per its site, collects transaction data from "40,000+ CRE professionals", screens it with machine learning and checks it with analysts, and says its data points "trace back to signed transactions." Titleman does not sell a comps database. It reads the records it can reach across 2,100+ sources, picks the comparables that fit one property and puts them into an analysis.
Side by side
| Question | CompStak | Titleman |
|---|---|---|
| Best for | Teams that want direct access to lease and sale comps across many markets | Teams that want an address turned into a sourced deal package |
| What it does | Lease comps (net effective rent, free rent, tenant improvements, escalations), sale comps (cap rate, NOI, buyer and seller, price per square foot), loan and property data, per CompStak | Property passport, comps, feasibility, value opinion and underwriting from an address, plus the OM, rent roll and T-12 if you have them |
| Coverage | 105 markets; office, retail, industrial, multifamily, flex, R&D and land, per CompStak | Records from 2,100+ sources |
| Where it stops | Supplies the data; choosing the comps for a given property and building the model is left to the user's own workflow, as far as its site describes | Not a comps database to browse; the text gives no final price and no buy or sell verdict |
| Pricing model | Exchange: access at no charge for members who contribute comps. Enterprise plans (CompStak One, CompStak One Connect, data delivery and integrations, strategic advisory) with no prices shown; "Request Demo" | Not listed here |
What CompStak is built for
CompStak describes two ways in. The Exchange is for brokers, appraisers and researchers, with the line "Contribute the comps you have to unlock the comps you need." The Enterprise products are for teams that underwrite, value or analyze property, and CompStak lists owners and operators, asset managers, lenders, private equity, brokerage firms and appraisal firms among the users. CompStak One Connect, per the site, adds Agent Connect and Rent Predictor. CompStak also states that "Data is never estimated or blindly added to the system."
What Titleman does with comps
Titleman's comps step follows written rules: one asset class, a radius of 1 mile by default and 10 miles at most, 24 months by default, and at least 3 priced comps before the set counts as enough. The subject's own sale is excluded. Rows that are not truly comparable come back marked "reference only" with the reason, and new construction is not priced from old stock. The same request returns the same rows in the same order.
Measured on production runs over the 30 days to 18 October 2026, the median underwriting took about 58 minutes (44 runs). That is a median, not a promise. An underwriting returns a memo and a live Excel model with about 1,000 data points: 159 found with a source and date, 607 computed by formula and 164 named as missing.
Who should pick which
- Research and leasing teams that need lease terms such as free rent and TI across many buildings: CompStak, per what it lists.
- Acquisition, lending and brokerage teams who need a sourced answer on one property, or on a list of up to 10 addresses in one BOV-at-scale run: Titleman.
- Teams that do both: use the comps database for market research and Titleman for the property-level package. For more on the comps question, see CRE comps software compared, and for the wider field, the best AI tools for commercial real estate.
How Titleman handles data lineage is described on the real estate data platform page. To see a comp set on a property you know, request access.
FAQ
What is the difference between Titleman and CompStak?
CompStak is a comps data company: per its site it gathers lease and sale comps from more than 40,000 CRE professionals and checks them before they enter its system. Titleman starts from an address and returns a comp set, value opinion, feasibility study or underwriting, with each figure traced to its source or formula.
Does CompStak publish its prices?
On the pages read on 19 October 2026, CompStak shows no prices for its Enterprise plans and asks visitors to request a demo. Its Exchange gives access at no charge to members who contribute comps.
Can Titleman replace a comps subscription?
Not if your team needs to browse and export lease comps across many markets. Titleman selects comps for a specific property and uses them in an analysis. It is not a database you search on its own.
How does Titleman choose comparables?
By written rules: one asset class, 1 mile by default and 10 at most, 24 months by default, at least 3 priced comps, the subject's own sale excluded, and non-comparable rows marked reference only with the reason.
Can the two be used together?
Yes. A team can use a comps database for market research and Titleman to produce the sourced package on the properties it is actually pricing. Titleman's Excel output uses live formulas, so outside figures can be added and checked.
