In Deutschland

Die Faustregel: Die monatliche Rate sollte 30-35% des Nettoeinkommens nicht übersteigen. Bei 4.000 € netto: max. 1.200-1.400 € Rate. Eigenkapital: mindestens 20% des Kaufpreises + Kaufnebenkosten (10-15%). Für ein 400.000-€-Haus: 80.000 € Eigenkapital + 40.000-60.000 € Nebenkosten = 120.000-140.000 € Eigenkapital empfohlen.

Kaufnebenkosten

Grunderwerbsteuer: 3,5-6,5% (je Bundesland). Notar: ~1,5%. Grundbuch: ~0,5%. Makler: 3-7% (oft hälftig). NRW/Bayern: 6,5% GrESt. Sachsen: 3,5%. Diese Nebenkosten machen 10-15% des Kaufpreises aus und werden oft unterschätzt.

⚡ CalcWolf Insight

Every 1% increase in mortgage rates reduces your buying power by approximately 10%. Going from 4% to 7% rates means you can afford roughly 30% less house on the same income — which is exactly what happened from 2021 to 2023.
