FAQs

It depends on your mortgage interest rate vs. expected investment returns. If your mortgage rate is below 3-4%, investing historically provides better returns. But paying off your mortgage offers guaranteed savings and peace of mind.

Most German mortgages allow annual extra payments (Sondertilgung) of 5-10% of the loan amount. These reduce your outstanding balance and total interest paid. Check your contract for the exact allowance.

A globally diversified stock portfolio has historically returned 7-8% annually before inflation. After inflation, expect 5-6%. Conservative estimates use 5% to account for fees and taxes.

In Germany, mortgage interest on your primary residence is NOT tax-deductible. However, for investment properties, mortgage interest is fully deductible against rental income, making the comparison more favorable for investing.

When your fixed-rate period (Zinsbindung) ends, you'll need to refinance at current market rates. This interest rate risk is a key factor — if rates rise significantly, extra payments during the fixed period could save you money.
