Not a bad idea if you get along very well with them. They would always be close by if you needed help with anything, or needed rides to appointments, etc, later on, plus you could share some expenses. I guess one downside would be that if you ever wanted to sell your portion or downsized house, you couldn't. But if you plan to leave it to them anyway, maybe that wouldn't be an issue.My daughter, out of the blue, asked if we wanted to go in on land and have a compound. Her and her DH were talking to another couple that did just that. It's a thing now. Supposedly saves money. We haven't talked about it since.
There would be pros and cons. Family close but in your own homes. Kid babysitting, future old people sitting.
Anyone heard of this?
