We did years ago, a resort condo. Have the contract written by your lawyer. Look at the sale in the same way a conventional lender would, require a substantial down payment, fees for late payment, and something concrete that defines when the buyer is in default. In the loan include a statement that this is not their residence and should the buyer go in default you are entitled to possession (foreclosure to clear the title). Do a credit check as well.
Our buyer was a builder and his wife. His business went belly-up so they defaulted on the loan several years later, we foreclosed. We rented it for another couple years, then sold at a substantial profit - again
