DH and I are looking to move into a larger home for our family (2 children). MIL lives nearby.
Some of the houses we've been looking at (at the top end of our budget) have very large gardens (.25-.75 acre). A couple with small buildings that could be converted into (or have enough space to build) a 1 bed granny annex at the end of the garden. DH is pushing for MIL to live in the granny annex so she can help cover the cost of the mortgage and make it more affordable for us.
I'm not at all in favour of this idea. I've said if we can't afford the mortgage without her living on the property and contributing we shouldn't be considering it. DH says although we could afford it, her contribution would make it more manageable (obviously!).
I'm worried that MIL will constantly be in our home or need DH to come to hers to help with something so we won't have much privacy. The homes we're looking at have large windows or bifold doors at the back so MIL would be able to see if we're in the room, have the lights on or off (so when we're home or not), etc. DH insists she'd want to be independent in her place. Except her post and groceries would be delivered to our home. She'd be parking in our drive and then have to walk down the side of our house and through the garden to get to hers.
AIBU that I don't want MIL living on our property?
Is there anyone with in-laws or their own parents that live on their property in a similar set up?
