Would you buy your parents or in laws house? Need advice please!

My father in law passed away this past year, it was devastating.

My husband has been focusing on his parents house which he calls now his “dads house.” He keeps asking me if my MIL offered a good price... would we buy it. Talking about buying it renovating it. It seems like his only focus is to buy the house now, which I find bizarre.

I bring up that his mom who is very much in love with the house prob won’t be moving any time soon but she does complain about the amount of work. I keep telling my husband that it will take atleast a couple yrs for us to be able to make the house practical and something she can take care of on her own. He tends to think it’s a family house.

When I bring up that his mom is young still and won’t move most likely, he gets real defensive and says that there are too many memories there for her. I think this is too fresh to be even talking about moving in his parents house i say next then he gets really defensive. I told him the truth yesterday.. it just came out. I told him that I don’t think his parents house would ever truly be ours even if we renovated it, I would rather build our own house. He got really mad with this and now we can’t even talk about our future.

Before I married him, I never thought he wanted to move back to his hometown and live that close to family. It’s making me really upset because now thats the only thing he can focus on now. I understand he must be grieving but it’s been almost a year . I let him vent and feel terrible I let what I say slip but I also wanted to tone down the talk about buying his dads house..
