Buildability™ vs PropStream
Data version: Q2 2026 · Last updated 2026-05-13
TL;DR. PropStream is an investor-focused property data platform that excels at lead generation, comparable sales, and motivated seller lists. Buildability™ is a per-property buildability analysis platform that excels at zoning, environmental risk, and feasibility scoring. PropStream tells you which properties to look at; Buildability™ tells you whether you can actually build on them.
Quick comparison
PropStream: nationwide property database with comps, owner records, motivated seller lists (pre-foreclosure, vacant, tax delinquent), MLS data, and skip tracing. About $99/month with add-ons. Strong in lead generation for residential investors and wholesalers. Buildability™: 142-factor Buildability™ Report per parcel covering zoning, setbacks, FAR, FEMA flood zone, environmental risk, infrastructure, and permit pathway. $29 per report or $249-$1,083/month subscription tiers. Strong in technical buildability analysis for any U.S. property.
Where PropStream wins
PropStream is the right tool when your question is "which properties should I be targeting in this market?" It excels at building motivated seller lists (pre-foreclosure, tax delinquent, absentee owner, vacant), running comparable sales analysis, and providing skip-tracing contact data. If you are a wholesaler, fix-and-flipper, or buy-and-hold investor doing high-volume residential lead generation, PropStream is built for that workflow. It also has strong MLS integration and automated comp generation.
Where Buildability™ wins
Buildability™ is the right tool when your question shifts from "which property should I target?" to "can I actually build on this parcel?" PropStream gives you the comps and the seller info; Buildability™ gives you the zoning code, permitted uses, setbacks, FAR, ADU eligibility, FEMA flood zone, environmental risk flags, and a buildability score. PropStream does not analyze zoning or environmental constraints in any depth. Buildability™ covers the technical due diligence layer that determines whether a deal is legally and physically feasible.
Best use cases
Choose PropStream if: you are a residential investor, wholesaler, or fix-and-flipper who needs lead generation, motivated seller lists, comps, and skip tracing. Choose Buildability™ if: you are evaluating whether a specific parcel is buildable, checking ADU eligibility, running development feasibility, screening collateral risk, or answering "what can I build here?" The two tools are highly complementary — use PropStream to find deals, then use Buildability™ to screen them for buildability before sending an LOI. Investors who use both report dramatically fewer dead-deal losses than those using PropStream alone.
Pricing comparison
PropStream: $99/month base subscription with usage-based add-ons (skip tracing, list pulls, etc.). Buildability™: free first report, $29 per single report, $129 for a 5-pack, or $249-$1,083/month subscription tiers. Buildability™ also offers bulk and API pricing for teams screening 200-3,000+ parcels per month, with a 30-day money-back guarantee.
