My niece (on my husbands side) has been kicked out of her parents - they are quite unreasonable people and we've always got on well with her. The reason they've kicked her out is because she goes out every Saturday and doesn't get up until 'gone noon' on a Sunday. Personally think this is fine as I was doing the same at 19.
She is going to rent somewhere, but due to where we live it will most likely take her a while to find something appropriate and she's said her aim will be to move out by January.
We don't want her to take advantage of being rent free in out house so was wondering on suggestions for rent to charge her, she earns £16,000p/a, and any real rules. The only things me and DH have come up with is to take care of her own room, not disturb the kids late at night and to just keep us posted (text us) if she is not coming home, or going to be really late so we aren't worried.
(We are also going to put the rent she gives us into a 5 year ISA in her name).
