Yes, you can sell part of your land if you have a mortgage, but only with your lender’s written approval. The mortgage lien covers your entire property, so carving off a parcel to sell requires the lender to formally release that piece from the lien through a document called a partial release. Expect paperwork, out-of-pocket costs, a financial review, and no guarantee the answer will be yes.
Why the Lender Gets a Say
When you took out the mortgage, the lender placed a lien on the whole property as security for the loan. Selling even a small strip shrinks that security, which is why the decision isn’t yours alone.
Federal law lets lenders include a due-on-sale clause in the mortgage contract, and nearly all of them do. That clause allows the lender to demand full repayment of the remaining balance if you sell or transfer any part of the property without written consent.1Office of the Law Revision Counsel. 12 USC 1701j-3 Preemption of Due-on-Sale Prohibitions Not every unauthorized transfer triggers an immediate demand, but the lender can call the loan. Don’t gamble on it.
What a Partial Release of Lien Does
A partial release removes the mortgage lien from the specific parcel you’re selling while leaving the lien in place on what you keep. Without one, no title company will close the sale, because the buyer can’t receive clear title.
The exact process depends on who owns your loan. For Fannie Mae loans, you submit a completed Form 236, Fannie Mae’s standardized partial release application.2Fannie Mae. Form 236 Partial Release Request FHA-backed loans follow a separate process under HUD guidelines.3HUD. Chapter 11 Partial Release of Security Portfolio lenders and other investors set their own rules. Across all of them, the core question is the same: will the remaining property still adequately secure the debt?
Will You Qualify
Partial releases aren’t rubber-stamped. For Fannie Mae loans, the mortgage must be current, and the loan must have been originated more than 12 months before the request. The release also cannot jeopardize the lender’s lien priority, and the remaining property must still be accessible from a public road.4Fannie Mae. Evaluating a Request for the Release, or Partial Release, of Property Securing a Mortgage Loan If your request doesn’t quite meet every requirement, the servicer can send it up to Fannie Mae for case-by-case review, which adds time.
Other loan types set their own thresholds. At minimum, expect any lender to require that the loan is in good standing and that the remaining land makes sense as standalone collateral.
How the Lender Analyzes the Numbers
The main test is loan-to-value on the property that will remain after the sale.
Fannie Mae uses a 60% LTV benchmark. If the post-release LTV is below 60%, the servicer can approve the release without requiring you to pay down the mortgage. If the post-release LTV is 60% or higher, you have to reduce the loan balance enough to maintain whichever is higher: the LTV you had before the release, or 60%.4Fannie Mae. Evaluating a Request for the Release, or Partial Release, of Property Securing a Mortgage Loan
FHA is more lenient. Under HUD guidelines, no principal reduction is required if the post-release LTV is 75% or less. Above that, the balance has to be paid down to bring the loan back within limits.3HUD. Chapter 11 Partial Release of Security
Beyond LTV, the lender will check that the remaining property complies with local zoning, has road access, and holds together as a functional parcel. Plan on several weeks for the review, and possibly a few months.
What You’ll Need to Submit
The application package is more involved than most sellers expect. Typical requirements include:
- The partial release application itself (Form 236 for Fannie Mae loans, the lender’s own form otherwise).
- A new property survey from a licensed surveyor, showing the parcel being sold, the boundaries of what you’re keeping, and the location of any structures.
- Appraisals showing the value of the property before the release and the value of the remaining property afterward. Some lenders order these; others accept borrower-provided appraisals from approved appraisers.3HUD. Chapter 11 Partial Release of Security
- A fully executed sales contract for the parcel.
You pay for the survey and appraisals up front. A straightforward boundary survey on a small lot might run a few hundred dollars; a large rural parcel with complex boundaries can reach the thousands. Appraisal fees add several hundred more. None of it is refundable if the lender says no, so budget for the risk.
Where the Sale Proceeds Go
Don’t plan on pocketing the full sale price. If your post-release LTV hits the threshold (60% for Fannie Mae, 75% for FHA), the lender will require enough of the proceeds to go directly toward paying down the mortgage principal to bring the LTV back in line.4Fannie Mae. Evaluating a Request for the Release, or Partial Release, of Property Securing a Mortgage Loan In some cases that means all of the net proceeds.
Even when your LTV is comfortably low, many servicers still require some paydown as a condition of approval. The exact amount goes in the partial release agreement. There’s some room to negotiate, but the leverage sits with the lender.
If the Lender Says No
Denials happen, especially when the remaining property barely covers the loan or when the parcel you want to sell holds most of the value. You have a few options if that happens:
- Make a lump-sum principal payment before reapplying, if the denial was driven by LTV.
- Refinance into a new, smaller loan on just the portion you want to keep, freeing the other parcel. This only works if you qualify for the new loan and the remaining property appraises high enough.
- Ask for a conditional approval, such as applying all sale proceeds to the mortgage or agreeing to escrow terms.
- Wait. Time, appreciation, and regular payments improve your LTV, and a request that fails today may succeed later.
There is no legal right to force a partial release. If the lender refuses outright, your alternatives are paying off the mortgage in full or improving the collateral picture until the answer changes.
Local Zoning and Subdivision Rules
Lender approval is only half the job. Your local government also has to allow the split. Municipalities regulate land division through zoning codes and subdivision ordinances, and requirements vary widely from one jurisdiction to the next.
Common hurdles include minimum lot size, minimum road frontage for each new parcel, setback rules that the split might violate for existing structures, and environmental or utility constraints. If the split creates a parcel that doesn’t meet the local zoning minimums, you’ll need a variance or rezoning, which adds time and uncertainty. Some jurisdictions exempt large-acreage splits from full subdivision review, but smaller residential lots almost always require planning department approval and a recorded plat map.
Watch out for landlocked parcels. If the piece you’re selling has no direct access to a public road, you’ll need to create and record an access easement across the land you keep. Courts generally recognize an implied easement by necessity in this situation, but relying on that doctrine instead of recording an explicit easement invites future litigation. Record the easement on the plat, name the benefited and burdened parcels, and take the ambiguity off the table.
Utility easements deserve the same care. If water, sewer, or electrical lines that serve your remaining property run through the parcel you’re selling, record easements preserving your right to maintain those lines. Do it during the subdivision process, not after closing.
Taxes on the Sale
Selling land is a taxable event, treated like any other capital gain or loss. The closing agent will file Form 1099-S reporting the gross proceeds.5Internal Revenue Service. Instructions for Form 1099-S (04/2025)
Allocating Your Cost Basis
To calculate the gain, you need the cost basis of the specific parcel you sold, not the basis of the entire property. The IRS requires you to allocate the original purchase price across subdivided lots using fair market value: multiply the total cost of the original tract by a fraction whose numerator is the fair market value of the sold parcel and whose denominator is the fair market value of the whole tract at the time you bought it.6Internal Revenue Service. Publication 551 Basis of Assets The difference between the allocated basis and the sale price is your capital gain.
If you’ve owned the land more than a year, the gain qualifies for long-term capital gains rates. High-income sellers may also owe the 3.8% net investment income tax on top.
The Section 121 Home Sale Exclusion
If the land surrounds your primary home, you may wonder whether the Section 121 exclusion applies. That provision lets you exclude up to $250,000 of gain ($500,000 for married couples filing jointly) on the sale of your main home if you’ve owned and used it as your residence for at least two of the past five years.7Internal Revenue Service. Topic No. 701 Sale of Your Home Treasury regulations do allow the exclusion to reach adjacent vacant land sold separately from the dwelling in narrow circumstances: the land must have been used as part of the residence, and the sale of the dwelling itself must occur within two years of the land sale. A tax professional can tell you whether your situation fits.
Closing and Recording
Once the signed partial release is in hand and any local approvals are in place, the transaction moves to closing. A title company or real estate attorney typically manages this stage. Several documents need to be recorded with the county recorder to make the sale official: the new deed transferring ownership of the sold parcel to the buyer, the lender’s partial release of lien, and, if a new lot was created, the subdivision plat map approved by the local planning authority.
Recording fees are usually modest. The bigger closing costs are the title search and insurance on the new parcel, any transfer taxes, and attorney or escrow fees. The buyer typically covers their own title insurance, but confirm who pays what in the purchase agreement. Make sure the partial release is recorded simultaneously with the deed. If the deed records first without the lien release, it creates a title cloud that’s fixable but a headache for everyone involved.
