It seems like that but isnt a straw man purchase based on inflating the price of a property then borrowing against that specific property? If you create a comp on property A then use that comp to borrow against property B then it seems legal. Its the same thing we all do in the market. We use comps to refi out cash all the time on our properties. Theres no law against buying something for more than its market value.
Its a gray line I suspect but not outright illegal. The self dealing seems to be out of play because there really isnt a rule that says a close relationship cant buy something from you. I can sell my mom my condo for whatever I ant to if she will pay. Its making sure she doesn't then do something with that specific condo that becomes an issue. Not what I do with another entirely different condo she has no ties to.
To me it seems like the ethical edge we all straddle when assigning contracts and double closing when we dont actually have our own money.
