I don't think they ever really asked. They just said hey, we're gonna remodel the old house, it's a house on top of a garage. He kind of went, ok suit yourselves. Then it eventually turned into them moving in. I think it's a good thing as he really could use some nearby help, im ten miles away but with my grandmas health issues, seconds count.
No. They want too but he's not ready to sell.
Haven't brought it up with him really. I'm trying really hard to just avoid a fight/feud etc. especially right before a very public and very large wedding.
