Random suggestions from a LL NOT in your state ....
Do nothing right now ! IN general as a LL if I don't evict a tenant when the order is ripe and I allow them to stay on, I have acquiesced to them being a tenant once again and if I seek to evict I need to do a full do over.
I am NOT in a high wage area ...in fact a rather low per capita income area ....and I can tell you that getting 24 /7 In home care for a loved one even if no strenous care is involved , runs about $ 480 a DAY and UP and that's just for the person...not meals or anything else like hair care or nails .
.
The rest of the family is getting a super whopper benefit from your nearly free presence ....
