With the land trust, who is the seller?

If the current pre-foreclosure owner executes a Quit Claim or Warranty Deed, to put the property into a trust, and if the Investor is the trustee of the trust, when you make an offer to purchase the property from the seller (the one that you’re going to send in with the SS package), who would be the seller?

Do you put the name of the title holder of record PRIOR to the conveyance into the trust, or is it the Trust that the investor is making the offer to? I know that ultimately, the Trust will sell the property to a retail buyer (once the buyer is found), but at the time when the SS package is submitted to the lender, someone or some entity has to appear on the Offer to Buy as the seller.

Any help would be appreciated …
