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.

Additionally, business purpose rental lenders have no ownership seasoning or short ownership seasoning to get cash out even up to 80% cash out.

Worst case I bet you could easily  and with minimal cost, section off the basement into storage units for your tenants as an add-on to their rent.

While doing 4 above want you to get a job with a self storage location covering during your off hours.  

Maybe for rest of season? 

@Cole Hoffmann I know a lot of people especially in this area tend to just fill the pool because it's use is seasonal in PA and like you mentioned there's a lot of costly maintenance.

Hi everybody-We own a property that is a main house and a separate duplex in a touristy area that is seasonal.

@Dave MooreBelow is a separate post I did for self Storage. 

I’d start doing these basic PMs every season to keep the emergencies at a minimum. 

I know for first timers they give you a green dot to wear so that seasoned professionals approach you to talk!
