At the bank, it is usually noted what the loan is for. This would also be the case with the renovation of the property. This should then also be taken into account in the event of potential care for the parents, meaning the loan for value increase x on the property is considered.
I would
- transfer the house from the parents to the child (gift)
- register a right of residence or usufruct right for the parents for their apartment
- possibly pay a certain amount to the parents (a kind of rent, care payment, compensation for the gift) which must be included in the gift contract
- then only start the loan and renovation.
The advantage is that in case of emergency, the state cannot include the final value achieved through the loan. A compensation payment in the gift contract also meets possible claims, although not completely.
You can hardly do it cheaper/better for the next generation. There is still a certain risk, but it is reduced.
It also applies, even if it is a bit morbid, the earlier the gift takes place the better.
One can rely on an inheritance, but due to the high care costs and the expectation that at least one parent will need this care, it would be foolish to act that way considering the monetary value of the property.
Buyout in a small amount does not work. There are no real tricks for this either. Money transfers are dangerous even in cash as the tax office etc. checks very carefully in case of emergency.
You can reduce possible follow-up costs somewhat and make them plannable for the worst case.
But you can no longer exclude them completely, at least not anymore.
