Who actually does the math?

Not the AI. Claude reads the listing and extracts the inputs; deterministic code runs every formula. The AI is never allowed to do arithmetic, so it cannot hallucinate your cash flow. Your max offer is solved, not estimated: the exact price where the deal stops clearing your targets.

What if a number is wrong?

Every extracted value is visible and editable. Fix it in one click and every metric recalculates instantly. You stay in control of the inputs.

Are the assumptions realistic?

Conservative by default, and yours to control. Vacancy, maintenance, capex, management, closing costs: all visible, all editable, and saveable to your buy box so every deal is judged by your criteria.

Already have a spreadsheet?

Good. Export any analysis as a fully populated Excel file with inputs, metrics, and projections filled in. We do the data entry; your spreadsheet stays for deep diligence.

Free to start: 3 full analyses, no credit card. Pro is $39/month (or $327.60/year) for 250 analyses a month. Teams run $69 per seat per month with a shared deal library.

From listing screenshot to full underwriting in 60 seconds.

The AI reads the listing. It never touches the math. Every input yours to edit.

How it works

From screenshot to clear analysis

No forms, no data entry, no guesswork.

Drop in a screenshot. Get a full analysis.

Upload any listing from Zillow, Redfin, or MLS and we pull the price, taxes, rent estimates, and property details automatically. In seconds you get cap rate, cash flow, DSCR, break-even rent, and a full investment projection. No data entry required.

Adjust assumptions. See the impact instantly.

Change the interest rate, vacancy rate, rehab budget, or any rent figure and every metric recalculates live. Model your best case, your worst case, and everything in between before you make an offer.

See your long-term investment returns.

Every analysis projects how your investment performs over time. See cash flow growth, equity buildup, and total returns compounding year over year so you understand the full picture before you close.

From the founder

Why I built an analyzer that keeps saying no

I was hunting multifamily in San Francisco. Every agent had a story; none had numbers that worked. And checking each story cost me 20 minutes of typing price, rents, taxes, unit mix, manually by hand into a calculator or a spreadsheet template while the good listings went pending.

Twenty minutes of data entry to learn a deal doesn't work is a bad trade. So I built an engine that does the typing for me: screenshot the listing, the AI pulls out every input, and uses math formulas that AI can't touch.

The engine told me the truth: at ask prices, almost nothing in San Francisco penciled. We walked away because of it. I never bought a bad building, and now I run the same numbers in Mid Missouri, where I have family and the deals cash flow.

That's what you're signing up for: the fastest honest no in real estate, with none of the typing, and every input yours to check.

Built for the way you buy

Wholesalers and acquisitions teams run the same first pass here. Different exits, same 60 seconds.

For Wholesalers

Underwrite every exit before you lock the contract.

Analyze the property once, then duplicate the deal and underwrite each version your way: different purchase price, different rents, different rehab. Show every buyer the case that fits their exit, with wholesale, flip, BRRRR, and rental calculators on hand for the exit-specific math. A deal that took 30 minutes in a spreadsheet takes 60 seconds from a screenshot.

See how wholesalers use Realastat

As a wholesaler this is nice to look at deals from multiple exit standpoints.

For Acquisitions Teams

Kill deals in one minute, not thirty.

Screen listings and OMs before they reach your full model. Realastat extracts the figures, runs the underwriting, and surfaces the KPIs your investment committee asks about. Analysts spend their hours on deals that pencil, and ARGUS gets the survivors.

Clean, extensive breakdown of all the data. I really like the widgets to amplify the real important KPIs.
