Dear SI,
Here is what we do in New Mexico, and I am sure that something similar can be done elsewhere. (Your attorney will let you know what you can do in your state.)
The instrument we use is a Real Estate Contract. It is similar to a Deed of Trust. Title does not change hands until the contract is paid off. The contract servicing agent holds two deeds in escrow. There is a warranty deed that will be released to the buyer when the contract is paid off. The second deed escrowed is a special warranty deed giving ownership back to the seller. This deed is released in event of default by the buyer.
The terms of an REC says that if the buyer is even one day late, the seller has the right to put the buyer "on demand." This means that the buyer must catch up on all payments, including attorney fees for the demand letter, within 30 days or the property goes back to the seller. No foreclosure. The escrow agent releases the deed, you record it, and the property is yours.
This is another reason to use a servicing agent as a disinterested third party between buyer and seller. The servicer can act as an escrow agent.
If you would like a copy of the Real Estate Contract form we use in New Mexico, send me a note. You can find my contact info in my profile.
Also, I am creating a school in which I teach owner finance concepts and techniques to people like you. Again, you can find info about the school in my profile.
Have fun...
