So my PIL are moving from a small two bed to a three bed. My BIL's live there and share a room, they are 31 and 25. Obviously they want to move out at some point but the younger one has some MH concerns and is out of work for the time being. That said, he has told me he hopes to start work and look for a flat to rent in the next year.
The older BIL has been in work for many years. He has a lot saved and I think the long term goal was to put a deposit down. He doesn't go out much and hasn't had a serious long term relationship, but I thought he wanted his own space.
Now the PIL are moving, BIL is talking about putting his savings into theirs so they can buy a bigger three bed, and he can have his own room. I know it's a bit more space, but that's not really freedom is it? I feel like he should still go with his original plan and save for a deposit. I know it's interfering but a room in your parents house isn't the same as your own place and he wouldn't be able to get that money back if he did decide to move out.
Would I be interfering to mention to him that it might be a bad idea to put his savings into a house which won't be fully his? I think both BIL's think that one day the house will be there's and they can buy their own houses but that doesn't account for the house being sold to pay for PIL's care. The whole family are quite close and like living together, as far as I can tell so I don't want to cause a rift but I don't want BIL to regret losing his savings.
