The product your selling is not new if someone has been living there3.  

Are you using a separate insurance product on top of the policy in place on each property.

@Waverly Rennie  I understand the buyers are cash buyers but that's for a finish product... who puts up the construction money.. your talking a significant sum. 

I would not use the product in a higher end flip or rental.

(I'm not revealing the name of my software - or promoting it - so that I don't violate forum policies or appear to be promoting my product.

We have sold only a few products like this several years ago but the investment after about 9 months would turn into a nightmare for the investor.  

But I also have always bought turnkey, so the only due diligence I've needed to do was verifying the provider and the product and property itself.

A blanket mortgage is not a product offered by Fannie/Freddie and is less desirable for most investors.Several friends of mine who own 50-200+ SFR rentals have successfully found small regional business banks willing to lender based in the NOI and cash flow of their properties. 

This would essentially roll the new roof into the mortgage on the house.The question is - would you do this - include the roof in the mortgage?

Being paid to learn essentially.
