ISO Closer for Subject To Existing Financing

[Trong Dang]

I'm looking for recommendation to an escrow company that can close a "subject to the existing financing" without having the lien holder to approve of the assumption of the loan by the Buyer for a deal I have in Tacoma, WA.  Or can this be done at all?  The seller is behind on payments and we're planning to catch it up to date, and give the Seller some cash at closing for this equity.  Buyer will take over the title and continue to make payment to the lien holder on the Seller's behalf moving forward.
