An estoppel letter is typically used in a transfer or conveyance of real property before the Closing transaction.It is a document sent to a bank (or other lender), from a homeowners' association (or condo association), to a city/municipality, or a tenant requesting a payoff of a mortgage, assessments or taxes due, or rental amounts due on a lease, to incorporate these amounts into the Settlement Statement for the buyer and seller of the real estate.

If there is going to be a wraparound (or Subject to) mortgage make sure you buy a title policy through a Trust friendly (build rapport for future reference and deals) title company as to satisfy The Seven-Day Notice Requirement: Sec. 5.016(c): "where the purchaser obtains a title insurance policy insuring the transfer of title to the real property" Even then, you are still closing a deal without protection of your assets.
