What data it sees

Do you need an account

No: the server works without sign-in

REIzer underwrites real-estate deals with a deterministic engine, so an agent returns real numbers instead of estimating them in prose. Give it a price and a few inputs and every call returns a 0-100 deal score, the metrics that matter for that strategy (cap rate, DSCR, cash-on-cash, monthly cash flow), stress scenarios showing what breaks the deal, break-even thresholds, every assumption REIzer filled in for you, and a shareable report page.

Six strategies: long-term rental, short-term rental, BRRRR, fix-and-flip, multifamily and new construction. best_use ranks all six against one property to find its best use. solve_max_offer works backwards to the highest price that still meets your return targets.

The four analysis tools are free — no key, no account. Two further tools return licensed sale and rental comparables and short-term-rental market data for a specific address; those require a REIzer API key.

Results are software estimates, not financial advice. Docs: https://reizer.io/docs/api/

analyze_dealUnderwrite a real-estate investment deal and get a 0-100 score, verdict, cash flow, cap rate, DSCR, stress tests, break-even thresholds, and a shareable report link. Strategies: ltr (long-term rental), str (short-term rental), brrr, multifamily, flip (fix-n-flip), newc (new construction). All rates/percents are FRACTIONS (0.0675 = 6.75%). Omitted operating inputs are filled with documented defaults and listed in assumptions.estimated_fields. Output is a software estimate, not financial, investment, tax or legal advice — figures are projections to verify, not recommendations. Free, no key; the response includes a shareable report_url.
best_useScreen ONE property across every strategy the provided inputs qualify for and rank them by deal score — answers "what is the best use of this property?". Provide a superset of inputs (price, marketRent, adr, occupancy, rehabBudget, arv, units, …); strategies missing inputs are skipped with reasons. All rates/percents are FRACTIONS (0.0675 = 6.75%). Omitted operating inputs are filled with documented defaults and listed in assumptions.estimated_fields. Free, no key.
solve_max_offerReverse-solve the Maximum Allowable Offer: the highest purchase price that still meets every return target (defaults: CoC 8%, DSCR 1.20, cash flow ≥ 0; flip: 10% after-tax margin + 15% annualized ROI). Returns the MAO, the binding constraint, and per-target price ceilings. Strategies: ltr, str, brrr, multifamily, flip. Provide the deal inputs WITHOUT committing to a price (use arv or an asking price as reference). Override targets via the targets object. All rates/percents are FRACTIONS (0.0675 = 6.75%). Omitted operating inputs are filled with documented defaults and listed in assumptions.estimated_fields. Free, no key.
list_strategiesList every supported strategy with its required and optional input fields. Call this first when unsure which inputs a strategy needs. Free, no key.
