You must first be divorced to consider this solution or have a property separation contract. You can take out a loan to buy out your former spouse’s share. If you have a mortgage loan in both names, you can continue to repay it alone if your income is sufficient to repay the initial monthly payment (decoupling of the loan), which requires the agreement of the lending bank. If the monthly payment proves too high, we could refinance the remaining balance of the mortgage loan over a longer term through another bank.
