The DealCheck alternative that skips the data entry.
DealCheck is a solid calculator. Realastat is an analyst. Upload a screenshot of the listing and get the full underwriting in about a minute, with every input still yours to edit.

The real difference: where your analysis starts
DealCheck starts with a form. You look up the property, then fill in and verify the inputs field by field. The math is fine. The data entry is the problem: several minutes of typing per deal, plus hunting down whatever the address lookup missed, multiplied by every deal you screen.
Realastat starts with a screenshot. Drop in the Zillow, Redfin, or MLS listing and the AI extracts the price, taxes, rents, and property details. Deterministic math takes it from there: cash flow, cap rate, DSCR, cash-on-cash, break-even rent, and a max offer solved against your return targets. The AI never does the arithmetic. Every extracted value stays visible and editable, each deal is scored against your buy box, and Claude can read that buy box, search listings, underwrite matches, and star the ones that pencil.
When DealCheck is the better fit
Honest answer: if you analyze a couple of deals a month, prefer typing your own inputs, and want built-in sales and rental comps in one app, DealCheck serves you well. It has been around for years and does what it promises.
Realastat earns its keep at volume. If you screen deals weekly, the data entry is the bottleneck, and cutting each first pass from several minutes of typing to one minute of review changes how many offers you get out.
