Selling on Seller finance on a renovated single family house with an over rehab budge

[Susan Tan]

I'm considering of selling my over budget single family house as a seller financed house to a self employed business owner home buyer and I become the bank. I'd like to get a large downpayment from the self-employed home buyer & a 10% interest rate for this buyer's 30year loan. But the problem is that the home buyer can get a DCSR loan too at 8% interest rate to buy my renovated house. Have you done a seller financed deal on an over-budget renovated house before? Looking for an alternative exit other than a normal house flip with an exceeded rehab budget.
