I know and there is no integrity or ethics in what you do.. if there was you would not charge more than a standard rate commission the only reason you do this is to steal equity from the unknowning and paranoid. 

In some states you disclose if you know about it, not an unknown. 

I'm trying to fully understand both pros and cons of seller financing to make sure I'm not pitching what I think is a win-win, when in reality there's unknown risk similar to what @John Woodrich was saying about the unexpected tax from recapture income.

In a real estate contract, typically the only 2 major contingencies (which the seller doesn't have to take) that sink a deal is an unknown material defect found during an inspection, and a buyer's inability to get financing.

Typically homeowners like to maintain the "unknown" lead status.  

When looking to buy in a new and unknown area what do you look for to find a growing neighborhood.

I learned to account for the unexpected for my next deals and leave a cushion for the unknown.  

They, too, have a fear of the unknown and the unknown is you. 

We let fear of the unknown hold us back more than we should have allowed it to. 

There are a lot of unknowns, variables, and people involved in real estate investing.
