If you don't have a realtor involved, often you are going to get to live with those things for as long as you own the house. 

I constantly hear people online (Social media) talking about getting an FHA loan and house hacking a 1-4 Unit property.

We will also finish up some renovation on our owner occupied house and pull a HELOC for an emergency fund and possible rental purchase fund.What are you looking to do, @Kristie Laufer? 

I have a house rent out there but it need some work Thank you in advance.

I do know that some of the supply houses are great for lighting/electrical/plumbing/HVAC/etc.

Your tenant would spend 99% of their time in other parts of the house and have very little exposure to this mold.

My current options include: Patio pavers (rubber and stone/brick)GravelCement padNothing/stick with grassThis is currently for my residence thats a house hack but I have a rental that the shed part of this applies as well.

Maybe new construction from a builder who is willing to sell 5 houses under one closing?

But I'm in a similar situation in my house hack.

Fiorillostart with a house hack or live in flip.
