I just gather tips and concepts and learn on my own and apply it to my market.

Like others have said, understand the concepts, then analyze the properties with today's prices and numbers. 

The concept seems to generally make sense, but it's unfortunate that there doesn't appear to be a grandfathering of older liens before they changed the rules and cost thousands of people tens of thousands of dollars in lost bid premiums. 

Your concept looks beautiful. 

I talked the brokerage into paying for an ad in the Houston Business Journal announcing that I, a “specialist” in automotive properties had joined the brokerage.

Now when the house sells, I post a journal entry to move that $500 to COGS.

The concept of "Boommates" would be an effective solution for many facing economic and social challenges.Sharing housing can benefit individuals and society by making better use of existing homes and creating supportive living environments.

@Luis Astudillo - I understand and I'm clear on the prepayment concept in the context of refinancing the loan or selling the property and squashing the entire loan balance.

Quote from @Bruce Woodruff: Quote from @Susan Maneck: Pay off loans for morons that can't comprehend the simple concept of paying back what you borrow.

So my cautionary tale is when buying seller financed paper, make sure you are very in tune to the value of the property.PS: Even if this started out as performing, same concept applies - make sure you know the numbers/values of the property.
