So, I would suggest using some of the other comps that you have listed and see if you would get a different perspective.

"Oh, I opened that a few days ago to get some fresh air because it was too hot and stuffy." 

@Dave Meyer, perspective matters.  

I'm particularly interested in understanding your perspectives on a few key points:1.

. -30k yr appreciation at (3%)-30k princ paydown yr1, increasing each year after..Cons:- 17 more self managed tenants with more problems than my current 19 freshly renovated homes- All properties need reno- Properties are priced at value, not below value therefore I can't recoup renovation costs from finance out after value add.          

Understanding Cash Flow vs Appreciation was big for me and I realized I was getting a single perspective from an agent a few years ago.

Not to argue, just sharing my perspective: brand new wholesaler doesn't need to close 10 deals/mo.

They usually aren't any good at vetting a seller financed transaction and representing your interests from a legal perspective.  

Installment sale in particular might be helpful from a tax perspective depending on your situation.

There are so many perspectives.
