My cousin did with her parents. It wasn't exactly an "inlaw suite"--it was a duplex and she (and her husband and baby) lived in one side and they rented the other side to her parents. And yes, my aunt and uncle paid market value.

It would depend on how much the utility bills increased. If they could afford it, I'd appreciate not having to pay a lot more in utilities having them stay with us. But no, I wouldn't charge them rent.

This is assuming rental income was never part of your financial planning to begin with.

Absolutely not. They didn’t charge me when I lived with them . Why would I charge them?

Oh my god, no

No.

Nope. Either not charging them or don't let them move in at all.

Yes if I only bought the house to accommodate them, needed the money to pay the mortgage, and they had an adequate retirement fund.

Enough so I could rent a different house.

No but if they wanted to contribute I would let them.

Nope

Nope

Absolutely not. They sent me to private school, paid for college, and purchased my first condo. It would be a bad look if I nickle and dimed them.

If they're capable of living on their own, it would seem reasonable to expect some sort of contribution; if they are not self-sufficient then no.

Depends on it I needed the money or not.

If your elderly parents want to move in with you into a basement in-law suite, would you charge them rent?
