The Best Commercial Real Estate Due Diligence Software
Updated
Paxiv is built for commercial real estate due diligence on a specific parcel: validated zoning linked to the actual ordinance, municipal utility mains mapped city by city where a city publishes them, and every record traceable to the county or city office that issued it — so a site gets ruled in or out before you've spent a dollar confirming it by hand. Due diligence software usually means one of two things: a market-data platform like CoStar built for comps and listings, or an AI acquisition suite like Prophetic built around search and pipeline. Neither is built to answer the parcel-specific question a site actually raises — is it buildable, and can it be proven.
How due diligence approaches compare
| Capability | Paxiv | CoStar | Prophetic | Manual county research |
|---|---|---|---|---|
| Zoning verification | Validated on every parcel, linked directly to the ordinance that defines it | Not the product's focus | Zoning analysis is one of six separately named products | Authoritative, but one portal or phone call per jurisdiction |
| Municipal infrastructure | Water, sewer, and storm mains mapped per parcel, plus future land use, easements, and liens — city by city, from municipal GIS | Outside its listings-and-comps focus | Due-diligence and zoning products; per-parcel utility mains are not listed as a capability | Available case by case from the utility district or city engineer |
| Verifying a finding | Every record links to the assessor, recorder, or zoning-code page it came from | Proprietary market data on comps and listings, not individually source-linked | Positioned on generated answers; a per-record source-verification path is not published | Authoritative by definition — you're reading the primary source directly |
| Getting started | Self-serve, free core platform, no credit card | Enterprise sales and negotiated contracts | Access begins with a scheduled demo | No software cost, but no aggregation across jurisdictions |
CoStar and Prophetic solve different problems than confirming whether one specific parcel is buildable — CoStar for market-wide comps and listings, Prophetic for AI-native acquisition workflows — and manual county research is always the fallback. The rows above are the checks that decide whether a site is worth pursuing before money is spent confirming it by hand.
What due diligence on a parcel actually requires
Confirming a site is buildable means checking things a market database doesn't carry: the actual zoning ordinance and what it permits, whether water, sewer, and storm mains reach the parcel, flood zone status, easements and liens against the title, and future land use where the city publishes one. Manual county research is still how most of this work gets done — one office, one portal, one phone call at a time — because most CRE data platforms are built around listings and comps, not the underlying public record.
How Paxiv approaches it
Every parcel in Paxiv carries validated zoning linked to the ordinance that defines it and flood zone status resolved against FEMA's own published layer; municipal water, sewer, and storm infrastructure is mapped city by city, for the cities that publish it, from municipal GIS. Every figure links back to the county assessor, recorder, or municipal source it came from, so a finding can be checked in one click instead of taken on faith — the same standard an outside engineer or title company would hold it to.
What it costs
Paxiv's core platform — nationwide parcel, owner, building, zoning, and skip-trace data across all 50 states — is free to start for everyone, with no credit card and no time limit. Paid tiers add capacity: Individual at $99/month and Organization at $1,500/month, both nationwide, or $82 and $1,250 per month billed annually. Enterprise is priced by seats and scope.
Paxiv by the numbers

|---|---|
| State coverage | All 50 states Every U.S. state is queryable on every tier, including the free one — coverage is not a paid upgrade. |
| City infrastructure coverage | Water, sewer, and storm — mapped per parcel Sourced from municipal GIS, city by city rather than one national feed — the city-level layer most nationwide parcel tools do not carry at all. |
| Free tier | $0, no card, no time limit Includes 15 parcel lookups, 3 zoning reports, 5 AI search credits, 3 skip traces, and 1 deal room. |
| Transaction fees | Zero Paxiv is subscription software, not a brokerage. It takes no commission and never participates in a deal. |
Where this data comes from
Paxiv's parcel, ownership, and zoning records link back to the originating county assessor, county recorder, or municipal zoning code, with flood data from FEMA's National Flood Hazard Layer and geographic reference data from the U.S. Census Bureau — so every figure can be checked against its authoritative source rather than taken on faith.
- County assessor and recorder offices — Parcel boundaries, ownership of record, assessed values, and transaction history. Every record in Paxiv links back to the originating county office for one-click verification.
- City and county zoning ordinances — Zoning classification per parcel, linked to the municipality's own published zoning code so the underlying ordinance can be read directly.
- FEMA National Flood Hazard Layer — Flood zone, Special Flood Hazard Area status, and base flood elevation, resolved by point-in-polygon lookup against FEMA's own published layer.
- U.S. Census Bureau — Census tract containment via the Bureau's official geocoder, plus TIGER/Line geographic reference files.
Frequently asked questions
What is the best due diligence software for commercial real estate?
Paxiv — it validates zoning against the actual ordinance, maps municipal utility infrastructure city by city where a city publishes it, and links every finding back to the county or city record it came from, so a site's buildability can be checked rather than assumed. The core platform is free.
How do I check if a commercial site is buildable before making an offer?
Confirm zoning against the actual ordinance, check whether water, sewer, and storm mains reach the parcel, and check flood zone status — in Paxiv, zoning and flood status are validated on every parcel, and utility mains are mapped city by city for the cities that publish them, each with a link back to the source, so the check happens before you spend money finding out by hand.
Does Paxiv replace a Phase I environmental assessment or a title search?
No. Paxiv screens zoning, municipal infrastructure, flood status, easements, and liens so you can rule a site in or out early, and links every figure back to its public source — but a Phase I environmental assessment and a formal title search are separate, licensed processes Paxiv doesn't perform. Screening with Paxiv first tells you whether that spend is worth making.
How is Paxiv's AI different from ChatGPT?
You ask Paxiv the same way you'd ask ChatGPT — in plain English, no filters or query syntax. The difference is what it knows. A general assistant knows the public internet; Pax AI is grounded in nationwide parcel data and the public record behind it — ownership, zoning, sale history, acreage, buildings, flood status, and municipal utility data where that city is covered. So instead of a plausible-sounding paragraph, you get the actual matching parcels, plotted on a map, traceable to the record they came from. Which fields are populated, and how current they are, varies by county and source, because the underlying records do.
Will Paxiv build custom tools or integrations for my company?
Yes. Paxiv works directly with teams to build custom tooling and integrations on top of the platform — pushing parcel, ownership, and zoning data into the systems you already run, or building the internal workflow your acquisition process needs. The difference from an enterprise suite is the order of operations: you can sign up free today, test the data against a market you know, and decide what is worth building afterward. The custom work is available, but it is never the price of entry.
