Frequently asked questions

Answers to the questions investors ask before their first analysis.

Is it really free?

Yes. You can analyze unlimited properties with every metric — ROI, cash flow, IRR, stress tests, and the Deal Negotiator — without paying or signing up. Premium ($29, one-time) adds live market data searches, more saved deals, and PDF export.

Do I need to sign up to analyze a deal?

No. The analyzer works with zero friction — no email, no card. You only need an account if you want to save deals or upgrade to Premium.

Are my numbers stored anywhere?

When you're not signed in, your inputs stay in your browser. We don't send them anywhere. If you sign in and save a deal, only the deals you explicitly save are stored in your account.

How accurate are the calculations?

Every metric (cap rate, cash-on-cash, IRR, NOI, DSCR) uses the standard industry formulas, and we show the full step-by-step computation behind each one — no black boxes. Compare it to your spreadsheet and you'll see the same numbers.

How is this different from a spreadsheet or a Zillow estimate?

Spreadsheets hide assumptions and don't stress-test. Listing sites skip vacancy, capex, and rate changes. The analyzer runs a year-by-year forecast, stress tests against downturns, and tells you the exact price or rent that hits your target return.

What does Premium add over Free?

The main unlock is live market data: 20 searches that pull real bedroom-level median prices and rents for any US zip code — so you can see instantly whether your price and rent assumptions are in line with the market. Premium also raises your saved-deal limit to 25 and adds PDF export. Note: live market data covers US properties only. The full calculator (KPIs, forecasts, stress tests, negotiator) works for any country.

What is the Market Data add-on?

A $9 one-time purchase that adds 15 more market data searches to your account — useful if you're evaluating several deals across different US zip codes and burn through your Premium allocation. It stacks on top of whatever searches you already have. US properties only.

Does the analyzer work for properties outside the US?

Yes — the full calculator works for any country. Every metric (cash flow, cap rate, IRR, stress tests, the Deal Negotiator) is pure math and requires no location data. The only US-specific feature is live market data, which pulls from a US real estate database and requires a US zip code.
