What's the difference between PropStream and DealCheck?

PropStream finds off-market deals at scale — public records, skip tracing and list building nationwide. DealCheck underwrites a specific deal cheaply with a calculator you populate. They sit at opposite ends of the process and don't really replace each other.

DealCheck, by a wide margin — free to $20/mo versus PropStream's $99–$699/mo. PropStream's price reflects its sourcing and skip-tracing data; DealCheck's reflects a focused calculator.

Some investors do: PropStream to source off-market leads, DealCheck to underwrite the ones worth analyzing. For South Florida on-market MLS deals, ReSharpe combines live data and underwriting with condo-document review.

PropStream vs DealCheck (2026)

PropStream and DealCheck are often mentioned together but do opposite jobs: sourcing off-market deals versus underwriting a specific one. Here's the honest comparison — and a South Florida option that does the analysis on live MLS data.

The details

PropStream earns its price if sourcing is your business: nationwide records, skip tracing and marketing lists. It isn't designed to underwrite a deal or read a building's documents.

DealCheck earns its place as the affordable calculator once you have a property: enter the inputs and get clean cashflow and a branded report. It doesn't source leads or pull live data for you. They're complementary tools, not substitutes.

The third option: ReSharpe

Both PropStream and DealCheck are nationwide tools. If you specifically underwrite South Florida MLS deals, there's a third option built for exactly that: ReSharpe pulls live MLS data into every listing, calibrates rent and value on 100,000+ real closed South Florida transactions (~7% median rent error, 80% valuation bands), and reads the condo/HOA documents for hidden risk — then outputs a branded client report. It's narrower in geography on purpose, and deeper because of it. See ReSharpe vs PropStream and ReSharpe vs DealCheck.
