Quote from @Jay Hinrichs:
Good for you too, Jay, for closing and funding so many transactions. I am glad things worked well for you over the years. But Scott is doing something other than what you do, which is seller financing owner occupied homes. You don't lend to owner occupiers. I read @Dan Deppen's earlier response on this thread and I think what Scott might be doing is employing RMLOs to originate his loans, loan servicers to collect the payments and attorneys to review his contracts and make sure he is compliant with all the laws and regulations.
You are right about high risk of default. I guess a lot of Scott's buyers are under water the day they sign a loan, so he must be regularly evicting and reselling some of those houses. There are ways to mitigate the costs and protect yourself to the extent possible. For instance, if he paid $40,000 to buy a house and sold it for $80,000 with $10,000 down, he could keep $10,000 in reserve and tap into it to hire attorney, file eviction case , remove defaulting buyer/tenant and continue paying off investor loan (if he used PML to buy that house) while looking for the next buyer to sell it. He takes the same risk as any landlord out there, since a lot of renters would not qualify for a mortgage and default anyway. But he has clear advantage of getting much larger deposit (landlord in most jurisdictions is limited to collecting 1.5 or 2 months' rent payment, which he must place in an escrow vs. $8000-$10000 Scott can collect and use for any purpose the next day).
Also, if you consider the fact that his 30 year mortgage is $100-$200 less per month than what local folks pay for rent, then it's not as predatory as it may sound at first. Someone who is paying $900/mo to rent a 3 br apartment is given an opportunity to pay $700-$800 mo with prospect of owning the house, if they never default. They could also fix it on their own (as some of Scott's buyers do) , increase the value and sell it at higher price than bought, pocketing the difference.
I agree with @Nicholas L. and you, that 99 out 100 people who try this won't make daily home runs and won't retire in Bahamas. But I see no reason why this can't be done by someone like Scott, or anyone who is successful in any real estate endeavor. And if someone tries it, without paying for classes or programs, they can either net a deal or loose X number of hours of their time trying it. You don't have to spend money out of the pocket on searching Redfin, making some phone calls, making offers and posting ads on Craiglist or whatever local media you want to use to sell the property. Yes, you will need a cash or PML to buy the house, but it is true of any real estate transaction with the exception of wholesaling.
This is obviously not a get rich quick scheme, and like with any business out there 99 out of 100 who try it will fail at it. But it doesn't seem to be riskier and more doomed to fail than BRRRR and other types of long term holding/land lording.
