Should I Pay for an Appraisal Before Requesting a Partial Mortgage Release?

Wait until your mortgage servicer confirms who must order the appraisal and what it will accept. Start with the company you send your mortgage payments to. Explain what land you want released and ask for the instructions for your loan in writing. Even if you end up paying for the appraisal, the servicer may need to order it.

What the servicer needs to evaluate

A partial release removes a specified portion of the property from the mortgage lien while the loan remains secured by the rest. Say you want to sell a strip of your yard to a neighbor and keep the house. The servicer may need the value of the property currently securing the loan and the value of the home and land that would remain after the release. An estimate of what the neighbor might pay for the strip answers a different question.

If you are still deciding whether to value two existing parcels together or separately, start with the two-parcel appraisal guide. If the proposed lot lines are still being worked out, see the boundary adjustment guide. Those are useful planning steps; the servicer’s instructions determine what report it will consider for the release.

What to confirm before you pay

  1. Who orders the appraisal, and when? Ask whether an appraisal is needed, whether the servicer must order it and whether you should submit the release request or supporting documents first. Confirm who pays and when the charge is due.
  2. Who must the report be prepared for? Ask whom it must name as an intended user, where it must be delivered and whether it must come through the servicer’s ordering process. If you already have a report, ask whether the servicer can use it before paying for an update or a second appraisal.
  3. Which property configurations, values and lot sizes are required? Confirm the boundaries of the property as it is now and the land and improvements that would remain. Ask whether the report must state the value and lot size for each configuration and whether it also needs a separate value for the land to be released. Lot size means land area, separate from the home’s square footage.
  4. Which documents define the proposal? Ask what map, survey or plat and legal descriptions the servicer wants, and how to send them. Be ready to show which land is staying, which land is being released and where the structures sit. Flag any access, utility or septic features affected by the proposed line.
  5. Which dates and acceptance rules apply? Confirm the required appraisal date or age limit, what date starts that window, and when the report is due. Ask what happens if the proposal changes or the request is delayed. The proposed after-release configuration and the date used to value it are separate instructions.

How Fannie Mae Form 236 works for a covered loan

For a partial release of real property securing a Fannie Mae loan under this process, the borrower submits Form 236 to the servicer. The form’s instructions call for a servicer-ordered appraisal dated within six months of the request date. It must report the property’s value and lot size before the release and the value and lot size after it. The instructions specify a separate value for the released portion when the loan is subject to Texas Section 50(a)(6). That clause does not create a general requirement for Washington properties.

Form 236 also calls for documentation showing the original, retained and released land and the locations of structures, along with original and revised legal descriptions. The Fannie Mae Servicing Guide uses the estimated post-release property value to assess the loan-to-value ratio. The appraisal informs that review; it does not approve the release. Ask your own servicer which program and requirements apply to your loan.

When a private appraisal may still be useful

You may want an independent opinion to decide whether a proposed sale makes sense for you. Define that planning question separately from the report the servicer requires. If you need only the report for the mortgage decision, follow the servicer’s ordering instructions first. See Alpha’s mortgage and private appraisal guidance for more on how those assignments differ.
