My 24 year old stepdaughter has been living in an apartment above our garage rent free for the last year. On Monday she brought her girlfriend over to meet us for the first time (we didn't even know she had a girlfriend, hell we didn't even know she was a lesbian). They have asked if they could move into the apartment together. I don't feel the girlfriend should get to live here for free. My husband doesn't think she should pay anything since she is his daughters girlfriend. If you were in this situation would you make her pay rent?
Edit: the reason my stepdaughter doesn't pay rent is because she baby sits for us 2 days a week and she helps around the house a lot. We thought it fair that she didn't pay rent in exchange for babysitting.UPDATE: So we talked to both girls and they both agreed that they will pay $200 a month each. The $200 my SD is paying will be put in a savings account every month and when she moves out, she will receive half of it back. They also have to provide their own food except for breakfast which they will be eating with us. The rest of the time they will cook in their apartment. We are making both girls sign individual rental agreement. We have also made it clear that when they are in the house, their relationship is to be kept a little under wraps, no kissing or cuddling, they can do that in their apartment. I have also made it clear to my SD that the younger kids are no longer allowed to come up to her apartment without approval from us. Even though we are not teaching our kids homosexuality is wrong, they are still young and impressionable. I agreed to a one month trial period to make sure it all works out.
