With anything in life, unforeseen circumstances happen, but maybe with presumably solid home and solid tenant screening you won’t have those large expenses in the first few years?

get the financials for the last 3 years and see what the average NOI is to get a handle on your cap rate.The unit they currently live in I presume you would give for free to the park manager?

That would free you up to do other things - presumably make money.

I know they went through a divorce about 4 years ago which I presume is why the house was left in such a state of disarray. 

Maybe not GC info upfront and Guarantor ID though I'd presume it'd be there if you're using one.

It is now September 3rd and the tenant presumably hasn't moved out.

Now the value of the LLC is higher because (presumably) the property is sold at a profit.

Presuming this is owner occupied you may have a tough time finding an attorney that will handle this.

No rational person could hold you accountable for the unforeseen if your and their due diligence was thorough.The best way you can maintain the relationship is to provide them more properties that will (presumably) make them money.

Presuming the floor is crooked enough for you to be concerned about it, I would definitely have him (or someone else) use a self leveling cement first - then lay the tile.
