I have seen kits that cover a big hole which I presume is for replacing the valve assembly without completely destroying the wall.

I'd rather have tenants who keep my property clean and pay their rent on time than tenants who destroy the place and don't pay rent.As a property owner, I don't need to know who exactly is staying in my rentals, since I don't require them to notify me when they have guests visiting and as to getting most cash flow, I know a guy who makes 3 times more doing Airbnb than if he leased out the place.  

My only worry would be multiple evictions/broken leases/destroyed homes which would eat up my cash flow to pay the notes down.

What happens if property is destroyed while your money is invested in the lien.

If there were issues arising from excessive damages, such as a borrower rehabbing and destroying the collateral, that is another matter for civil courts to assess consequential damages.That leaves seller financed transactions to be assessed, to the financial side.Dodd-Frank, the SAFE Act and all other underwriting guidelines fail to address the ownership of the note as an asset, much has to do with servicing and reporting requirements, but aspects of asset valuation are totally ignored.

That's only going to cost you money when they destroy the carpet, scratch the floors, and walls.

as well as destroyed the frame of the bedroom door so a new prehung door was needed.

I believe there will be changes in the energy landscape (see Solar panels could destroy US utilities - according to US utilities) in the next few decades.

@Guillaume DerouetIf you buy the home with any form of bank financing and then quit claim the home into your LLC, the home is still attached to you and your SS# so yes, if you get foreclosed it will destroy your credit.  

Because once the sale goes through he could freak out and start majorly destroying the place just because of spite.
