Real Estate Analyzer

Underwrite 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.

Screen 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.

Reverse-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.
