Can I still approach a short sale with seller financing?

South Carolina being a lien theory state, one would normally have an attorney draft a mortgage (which creates a lien on the property and makes the full balance due upon sale) and promissory note (which outlines the payment terms, interest, etc).

@Jesse Lewis I think a good question is, do you have any experience in sales?
