that potentially is just a registration system, nothing to do with visa exempt or the time you can stay

The house can be owned jointly, but not the ground it stands on. Have it in her name and make sure you have a usufruct in the documents that grants you the right to lease for 30 years if you run into a scenario in which your wife dies before you. Forget about all the people here screaming you will loose it all as they are only reflecting on their own lack of social skills and in any case (and country) life is a gamble
