This may be true, but the inventory released is pent up due to expiries from covid forbearance, most likely all of these loans will be heavily scrutinized by the numerous regulators, and will be difficult to navigate. 

This is especially true given how booked out some contractors have become.

@Bruce Woodruff True, true, Bruce, good input.

If someone could clear say $25000 to $50000 in true profit flipping, but it would take 5 to 10 years to do renting (long term) there is a good point in selling.

The difference in price between the existing mortgage and the purchase amount is made up by the seller carrying a subordinate lien or a private party carrying a second lien, or a partner being given a percentage ownership for providing the down payment.The second way to accomplish a true nothing down deal is to find a private lender that will lend 50-60% LTV and does not require the borrower to contribute capital, with the difference being made up by the seller carrying subordinate financing.Finally, a nothing down deal can be accomplished if the seller is willing to carrying a note for the full purchase price.
