Reasons to sell the seller on the Owner financing might be, because you are going to do a substantial rehab to the property, or that the property doesn't have any buyers, and this is a way to sell the property.Seller Financing works a lot better when there is not a realtor to pay, where a realtor's commission could be 6%, which on a $300,000 Purchase would be $18,000.An additional option you might consider if you are looking at purchasing this property to do a flip, or fix and rent, is you could propose seeing if the seller would partner with you, and you would secure a Private Loan for 50% of the sales price, plus the rehab, and if there is enough upside equity, you would probably be able to do a cash out refinance and pay off the seller that way.

The SFH originally cash flowed the best at about $900/month until I refinanced it to buy something else.

These advantages of using DSCR loans for refinances using the BRRRR method include:More flexible seasoning requirements: As of April 2023, the seasoning requirements for conventional cash-out refinances is now 12 months, but many DSCR lenders are still at just six months (with some even as little as three).
