Wholesale price $118,500 to you, Under Contract for $139,900, Rents to the current buyer for $900 per month, Current cost for principal, interest, tax, insurance, and home warranty $665.I can't speak for others, but that makes no sense to me.What do you mean $118,500 to me and under contract for $139,900? 

In order to mitigate some of these items that the retail buyer CANNOT see but can be issues nevertheless, I would always highly encourage paying for a year's worth of Home Owner's Warranty.  

You should have a Certificate of Occupancy that seller provides that states that the unit is "legal" Also if it's a legal three family it would need to be registered with the State and there should be a valid green card.

The origination point of the mortgage is when my company/trust/joint venture purchases it as a non-owner occupied property further validated by the seller leaseback. 

If you're concerned about deferred maintenance, put a clause in the contract that the seller is responsible for deferred maintenance through X period for a ceiling of X amount of dollars and then get a home warranty. 

Anyone who asks herself these questions has very little chance of become Gordon Gekko ;)I understand where you are coming from, but the point made by others here are valid as well.

That happened with my microwave in my SFR and the home warranty company. 

The 'ROBS" approach could be a valid alternative (as suggested above) but you still need to do the math as there are costs associated with that investment structure.  

The Seller can issue you a Special Warranty Deed or  a Quit Claim Deed.Good Luck.

I was at Lumber Liquidators yesterday and the guy showed me a product he compared to allure with a 50 year warranty, and it was $2 a SF compared to allure $3/SF (over 1300-1600sf, were talking some $!).
