Designed for the Next Era of Real Estate

Fast, affordable, and fully open-source utilities built for agents, buyers, and developers.

FHA Compliance Shield

Protect listings from costly Fair Housing Act violations. Our scanner scans copy for 50+ discriminatory phrase patterns, flags protected classes, and generates a compliant rewrite.

📊

Investor Financials

Generate detailed, rounded analysis metrics. Instantly calculate cap rate, cash-on-cash return, DSCR (Debt Service Coverage Ratio), GRM (Gross Rent Multiplier), and mortgage cashflow with default estimates.
