Is house construction financing possible? - Fully paid-off house

But it is allowed. 10 years apply only to rented properties.

It would be great if the OP also responded to the counter-questions and suggestions. It gives the impression that he just wants to hear "alright".

He posted his contribution today at 8:55 AM and now it is 12:45 PM. There are supposed to be people who also have to work concentrated for several hours at a stretch or have appointments where they cannot be active in forums all the time on the side.

Even though there are, of course, specimens here in the forum who write something once and then are not seen again, a bit more patience can be expected.

Another question. The house was purchased in 2014. Is it allowed to be sold again before 2024 without paying the exorbitant taxes?

Yes, after only five years, as long as you live or have lived in it yourself.

If the property was exclusively owner-occupied, there is neither a 10-year period nor a 5-year period, but none at all. Theoretically, you can buy and move in in January 2020 and sell and move out again in March. If the property was rented out in the meantime, it must have been owner-occupied in the year of sale and the two preceding years. Then the 10-year period can be undershot despite temporary renting.

Sorry, you are right. So two years of personal use, provided it was rented out before.
