Landlord wants to move-in with us
I live in a WG with 3 rooms. One is mine, one is my partner's, and we sublet the third one. The person who was living with us will leave at the end of this month.
At the end of April, my landlord sent me a message saying that, for personal reasons, he was looking for a place for himself. He said that it is really difficult to find an apartment (we live in Köln), and he wanted to let me know that he might have to ask for the apartment back. He then asked if there was a room available in the house that he could rent to at least start his life again. I stalled him until we were already in May, so in the worst-case scenario, we would have the apartment until the end of August.
But the situation is: I don't want to live with my landlord, but at the same time, my partner and I want to move to Spain this year. We haven't planned anything yet; we still need to decide on the city and look for jobs there, but what I definitely don't want is to have to move to another apartment for 1-2 months just to move again. I talked to my landlord about this, and he said he would be flexible with when we are leaving, and he also recognised that it is weird to live with a landlord, but he has WG experience, and he will still be looking for another place.
I am leaning towards renting him the room, so we can guarantee our house, but at the same time, I'm afraid of being super uncomfortable. We are 27 y/o, and he's probably around 50-60. I already put my boundaries with him and said we would need a contract and that he also needs to participate in maintaining and cleaning the house, but we can never be 100% sure people will be ok to live with.
I don't need us to interact or anything, obviously, but I just don't want to feel like I'm not in my own house.
Opinions? Has anyone experienced something like that?
p.s. I think he got divorced.
