Gita,At least the way I prefer to do things is to only run accrual based accounting activity on my day to day operations.

I'm new the notes world and frankly the 3-year locked in PPR preferred return of 12% seems almost too good to be true if they in 16 years have never missed a payment or failed to repay principal.

Preferably a duplex.

That sounds like a lot of work and I'm sure he would prefer to avoid that work and just sell it for $1.9m or $2.0m.if I were to buy it from him, to get to cash flow neutral I would need to increase rent on all 6 units to market rates and my monthly payment would need to be close to $6.2k/month, which would be $100k down payment, $1.7m loan with seller financing at 2% interest rate and flexible ballon payment.What would you do if you were me?

Super nice guy, and a genius.You can also go checkout Divorce Lending Association and find a local CDLP if you'd prefer.

As far as benefit to the seller goes, @Matthew Paul I think you are probably right on the money and regardless of whether they would have preferred to stay in this house rather than move, it is likely providing them some excellent cash flow; and I'd be hard-pressed to come up with a deal that serves both parties better than the current situation. 

Whether that's mobile home parks or any other kind of commercially valuated endeavor is a matter of personal comfort and preference.
