Until there is a judgment on the lien, it is suspect.  

I suspect the average NPN who is just starting out and or like the OP needs investors to buy the notes in the first place will have a difficult time with this strategy unless they find some other unsophisticated investors that they can talk into that strategy..But for me I LOVED hypo's  We did them on Timber ground I logged and then resold to folks that were going through the arduous process in Oregon of getting building permits on rural lands.  

I suspect that by the time you are in a position to pay all cash, you will have the answer to your own question ... that is step 50 ...

In addition to the fantastic responses others have provided, I just wanted to add, @Nick Doria, that your worries about not having Section 8 tenants even suspect a whiff of discrimination, since they are a protected class, is certainly reasonable.From the landlording podcasts, I've heard many useful tips that are relevant here for you.

@Leo Don, I suspect that the author is making more money from the Book than they are from Real Estate (and, that was their intention)!

I suspect these some of these folks have taken a motel course from some SMARTIE, who brain washed them into thinking they are real estate investors, OR SHOULD I SAY WHOLESALER.There is more to being a successful investor than taking a motel course from a SMARTIE.There are so many bad programs out there searching for your money, they want to teach you how to get rich. 

That particular property is still being rented by tenants, and I suspect the tenants would be willing to carry over to me.

@Joel Owens  I suspect in her farm average sales price even for wholesale is closer to 400 to 500k .. not 50 to 100k.. and I totally get you on agents that work in those price points.
