BIL moved in with us just before lockdown, had been living with another family member briefly but they fell out and I suggested to my partner that BIL move in with us. He was grateful and said it would just be till he ‘sorted himself out’. He had no job at the time and he was paying a small amount of rent.
After about a year he did get a job but his rent remained the same. Thought he might offer to up it as he was now earning but he didn’t. Only when the fuel prices rocketed and I told him what our monthly direct debit was did he offer to up his rent which we were grateful for.
Now my son is moving out and renting a flat with his girlfriend. He has a large bedroom with en-suite and a small lounge. I want to keep his room ‘his’ for a while as I think he may struggle financially as he is a low earner and if he needs/wants to come back he can. If he doesn’t, we live in an area where a language school are always looking for short term accommodation for students. If we have someone come to stay we can put them up there.
BIL hasn’t as yet asked about the larger room but I think he might. AIBU in not wanting him to have it? His rent covers all everything including meals and is reasonable and is a help to us and he is easy going enough but it was only mean’t to be short term. He never helps with necessary chores like unloading dishwasher or putting bins out and you may think why should he if he’s paying rent but it would be nice of him to offer.
