We have a house with a full basement being converted into a little one bedroom apartment. Apparently DH and I have been on totally different planets as to what will be done with this little apartment.

*I* thought that SD23 (still at home due to disability that prevents her from driving, so everything is harder for her)would be able to live there free or near free if in college full time in order to help launch her into a world that is harder for her than other people due to limitations outside of her control. She's a good kid. But, I was thinking this apartment would be for HER, and would come with some limitations- ie no boyfriend. If she wants to play house, she can move out and play it for real. This apartment would be for her to have some autonomy while still having a safety net and saving money.

DH wants to rent it to her at a small discount off of going market rate, but says she can do whatever she pleases and BF can move in. (my thought- Why would she stay at home, even in a basement apartment, for a "small" discount is my first thought. Doesn't seem feasible. If I'm gonna have family up my ass 24/7, it will be because I'm getting a HUGE benefit from it, not 10% off.)

Second issue- he wants no time line of how long the apartment could be used. I say college full time, then once you graduate 6 months to a year and you're goners. He says unlimited. I really see the groundwork here that he wants his son to live with us until he's 40.

So- would any of you allow a SKid (or Bio, even!) to live in a basement apt with a boyfriend/girlfriend? And if so, how long?
