Shari - I know of one real estate licensee (DRE Broker & NMLO) that has tried to offer this service (installment sale assistance) to real estate brokerages however her big issue is getting paid, especially when the deal doesn't go through.Since my model, for many years, has been to work with attorneys (probate estate and trusts) I've had some experience in this.
