Selling · Fannie Mae B5-3.4-01Selling a house with a PACE loan: why the buyer's lender wants it paid off

Property Assessed Clean Energy (PACE) loans are made through local programs to pay for energy-related improvements – solar panels, roofs, windows, HVAC – and are repaid through the property tax bill. They typically have automatic first lien priority over mortgages recorded earlier. Fannie Mae's uniform security instruments prohibit liens senior to the mortgage, and Fannie Mae will not purchase a loan secured by a property with an outstanding PACE loan unless the PACE program does not give it priority over first mortgages; a PACE loan structured as a subordinate lien or an unsecured loan does not block the loan. The loan application asks the borrower whether the property will be subject to a PACE lien with priority, and the lender whether it currently is. For a seller, that means a priority PACE balance usually has to be paid off at or before closing for a buyer using a Fannie Mae loan – which comes out of the seller's proceeds. Finding it early matters: it shows up on the property tax bill and in the title search, not on the mortgage statement.

What a PACE loan is

  1. Purpose

    Energy-related improvements financed by a local program – solar, roof, windows, HVAC.

  2. Repayment

    Through the real estate tax bill.

  3. Lien

    Typically first lien priority, ahead of mortgages recorded earlier.

Fannie Mae's rule (B5-3.4-01)

  1. Priority PACE lien

    Fannie Mae will not purchase the loan while it is outstanding.

  2. Subordinate or unsecured PACE

    Does not block the loan; standard underwriting.

  3. Loan application

    The borrower and the lender each disclose a priority PACE lien.

What the listing TC can do

  • Ask the seller at listing whether they financed solar, a roof or windows through their tax bill.
  • Look at the property tax bill for a special assessment line – that is where PACE shows up.
  • Ask title for the PACE payoff together with the mortgage payoff, so the seller's net is right before the buyer is under contract.

Questions sellers ask

Do I have to pay off my PACE loan to sell my house?

Often yes. Fannie Mae will not buy a mortgage on a property with an outstanding PACE loan that has priority over first mortgages, so a buyer with a Fannie Mae loan generally needs it paid off at or before closing (Selling Guide B5-3.4-01).

Where can I see whether a house has a PACE loan?

PACE loans are repaid through the property tax bill, so they appear on the tax bill and in the title search.

Is every PACE loan a problem for a buyer's mortgage?

No. If the PACE program does not give the loan priority over first mortgages – a subordinate lien or unsecured loan – Fannie Mae's standard guidelines apply.

On the seller side, ClosingCode's checklist puts "Request mortgage payoff statement" in the first week – ask title for the PACE payoff at the same time.
