AIBU to let my adult nephew move in after rent rise from my sister?

[YearsOfLife]

My nephew is 24 and has been working full time for about a year after finishing university. When he first started working full time, my sister was charging him £500 per month to live with her and her partner. She has now told him he needs to pay £800 per month which he isn’t happy about as he is trying to save for a house deposit as well as having other costs and wanting to socialise. He spends a lot of time at work or with his girlfriend and friends so I do think £800 is a lot.

Our children are similar ages and my nephew has asked if he could live with us, paying £400 per month. We are happy for him to live here but it is causing a huge problem with my sister and her partner. They don’t think we should allow him to stay with us.

On the one hand I can see why my sister thinks we shouldn’t get involved, but on the other, he’s our nephew and an adult and if we’re happy for him to live here, he should be able to.

My sister has accused us of trying to make money from him which is untrue as we don’t charge our own children anything to live here and IF we take anything from our nephew, it won’t be £400 per month. This isn’t about money for us. I agree with my nephew that £800 is too much and want him to be able to have a life and save like my own children.

AIBU to say he can live here?

Life's hard enough these days! If someone is offering to help you, take the help I say.

OP's nephew has already managed budgeting in a shared household. He has demonstrated his abilities. This isn't some dosser living off his mum.

I would let him live with you and charge him £500 per month.
I would then keep £250 for rent and save £250 for him and give it back to him when he leaves. That way you are not under cutting her, she has a choice if she keeps his rent the same and he stays with her. If they were short of cash I would understand it.

Whose house is it, I was assuming hers?
I assume you have the room for him and one more wont make a difference.

I haven’t read all the replies you’ve had. But for me I do think there is more to the story but not in the way that your nephew isn’t telling the truth. I think it’s more the way your sister has been as a parent over the years because her reaction seems ridiculously mean. I know it’s your sister but she doesn’t come across as a very nice person who has always put her children before herself.

Im glad you said yes to your nephew and I’m glad he has you and your husband. You have def done the right thing x
