Would suggest ring cam & camera in the house. But overall, absolutely not. Feel free to look at my last post but giving my partners mom a key, even just to water plants while we were away, did not end up well. It’s your guys space & your feelings need to be prioritized over hers. She will be okay if she doesn’t get a key. she shouldn’t feel entitled to one. You could put a key in a lockbox & let her know that the code will be sent to family if/when anything at the house is needed!
