Hi PH 👋 we built Mainaro because "the rent" tells you almost nothing about whether a property actually makes money. After interest, amortization, depreciation and German taxes, a "good" flat can quietly run at a loss. Mainaro has two parts: • Free location analysis — transparent scoring for every German municipality, built on official data (land values/BORIS, Destatis, labour market, OSM). Every point is traceable to its source, no black box. • Portfolio manager — after-tax cashflow per property, loan & refinancing history, DSCR stress-test, exit simulation and speculation-period tracking. AI extracts values from your purchase, loan and rental contracts; you confirm, the engine does the math. Privacy by design (GDPR, pseudonymized). Free for your first property, Starter from €4.99/mo. Would love your feedback — happy to answer anything!
