The main drawback with seller financing is the buyers will almost surely pay higher interest compared to a market-rate mortgage from a bank.
Seller financing does not have more flexibility in changing the interest rate charged by offering non-conventional loans as the financial institutions have. In long term, the higher interest could eliminate the savings gained by avoiding closing costs with seller financing.
Even with seller refinancing the buyers need to show their ability to repay back the loan.
Like other real estate purchases, a seller financing buyer will need to pay for a title search to guarantee the deed is accurately described and free from impediment.
Other charges like the survey fees, document stamps, and taxes may also have to be paid. You as a seller are in a situation where like the banks, you don’t have a staff of employees who can chase down the defaulter or file foreclosure notices for you.
Maximum the court could order the buyer to reimburse those costs, but if the buyer claims bankruptcy, it will be a difficult situation.
The seller should have a mortgage note on the property, stating that it has a due on sale clause or an alienation clause. When the property sells, these clauses require full repayment of the current mortgage.
Both the buyer and sellers should engage experienced real estate attorneys to draft the paperwork while closing the deal and to make sure that all clauses and events are covered.
