While I agree with you on paper, I’ve never had a landlord make it easy or convenient for any of those things in my experience. Usually they’re MIA and can’t seem to get anything done without a fuss honestly. Could just be my luck/the types of places I rent to be fair on that though.
It’s definitely possible, but Garza is also a really common Hispanic name. I could personally name a few Garza’s off the top of my head who aren’t related at all actually lol.
That being said, this all sounds sketchy as hell already, so who knows? Can’t say it would surprise me at this point.
