Berechnung

Gewinn = Verkaufspreis - Kaufpreis - Renovierung - Grunderwerbsteuer (2×) - Notar - Makler - Spekulationssteuer. 70%-Regel: nie ueber 70% des Nachher-Wertes minus Renovierung kaufen.

In Deutschland

Die doppelte Grunderwerbsteuer (3,5-6,5% bei Kauf UND Verkauf) und die Spekulationssteuer (unter 10 Jahre Haltefrist: voller persoenlicher Steuersatz) machen Flipping in Deutschland weniger lukrativ als in den USA.

⚡ CalcWolf Insight

The average house flip in the US takes 6 months and yields $67,000 gross profit — but 28% of flips break even or lose money. The difference between profitable and unprofitable flippers: discipline on the 70% rule, accurate rehab budgeting (with contingency), and fast renovation timelines. Time is the enemy of flip profits — every extra month costs $2,000-4,000 in holding costs.
