Thanks for weighing in, always appreciatedAS long as they are not creating infestations and Mold and are just normal tenants. you know mattress on the floor  cloths heaped in a pile in the corner  one couch one big screen and maybe a table to eat on.. but no bugs or mold then thats the main issue I think 

That's a seperate issue that's going to be handled eventually but the big issue is I suspect that an occupant in one of the units is dumping large objects next to and inside the dumpster (ie doors, mattresses, an elliptical....) that I then have to move out and pay to send to the dump.

We packed up our TV, Keurig, some clothes and blow up mattresses and left our cold/electric-less house and hung out at the flip house for a few days.

How about this idea.What if your Dad sold his hoarder house and put the hoard in several small storage units.Then you and he move in together and house hack something bigger (but that unit is known as YOUR unit--he lives with you).Both share management responsibilities sensibly and also profits and losses as partners.All new hoarded hoard things MUST go into a small storage unit.Or keep the hoarder house and rent it out--but that keeps your down payment cash pile the same.You can buy all new furniture and mattresses at IKIA or Target and have a fully furnished apartment on the cheap.

The big thing is also to rent fully furnished units. kids nowadays just want to move in, mattress have to be legally changed out within every five years. 

I had a new tenant coming in the next morning at 8 am.She left the frige and cupboards full, some abandoned dressers and mattresses, trash and random stuff.

One of my tenants living in the basement units stopped paying after Ida quoting her mattress and some other stuff was damaged.

You probably don't want his kids filing judgments against you and asking you to "return that golden ring worth 100k that he had hidden in his mattress".. 

Our new tenant was on an air mattress having sex with some guy.

I replaced all flooring, scraped the popcorn ceilings, new kitchen appliances, new paint and new furnishings except the mattresses.
