1. Selling the entire house: completely unprofitable, because the house could not be sold at a price that would allow breaking even. (prepayment penalties, not an ultra deluxe premium location with completely overpriced prices, etc.) One estimates a loss of about €50,000 in the end. So it is basically off the table.
Sounds strange to me. On the one hand, you claim that he earns enough to cover the house alone, on the other hand, there is more debt on the house than it’s worth. That doesn’t add up.
2. Renting out the house and covering the financing with the rental income: could be done, but new houses wear out too quickly with tenants who have several children (without children the house would be too big and impractical). Also, the "standard" rent assumed is set too high; not everything would be paid for. Overall unprofitable and not a great solution either.
That doesn’t add up either. If the property pays for itself with the rent, then it can also be sold reasonably well. I suspect that the rental income would not cover the loan, so both would have to keep contributing permanently or the value of the property would not be maintained.
3. One buys out the other's half of the house: theoretically the best solution. He would take over her half, she would transfer her half to him for €1. However, real estate transfer taxes and notary costs amounting to about €10,000 would apply. She doesn’t have these. Furthermore, the bank won’t release her from the contract because he supposedly doesn’t earn enough. But actually, that’s not the case.
en.
If case 1 applies, his loss amounts to about €25,000. Case 3 involves €10,000 costs, therefore saving €15,000, supposedly a total of €40,000.
As I said, I suspect that not all information/assumptions are correct; if they were, case 3 would be quite painless. But I think the bank has its reasons why she cannot get out of the loan, and then it eventually quickly comes to a sale, forcibly if necessary.
