You need to be there and keep your eyes on everything done every single day . Also, even if you are married, you need a lease from your wife for the land, you own the house but the land is hers. I would recommend depending on your age at least a 35 year lease if not longer any attorney can handle that for you, it’s very common and protects you even if you get divorced, you can still live in the house for those 35 years or whatever time is designated .
