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 that can run weeks or months, and no guarantee of approval.
Why You Need the Lender’s Permission
When you signed the mortgage, the lender placed a lien on the entire property as security for the loan. Selling even a narrow 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 virtually all of them do.1Office of the Law Revision Counsel. 12 USC 1701j-3 Preemption of Due-on-Sale Prohibitions That clause lets the lender demand full repayment of the remaining balance if you transfer any part of the property without written consent. Lenders don’t always call the loan the moment an unauthorized transfer happens, but they can, and that risk isn’t worth taking.
What a Partial Release of Lien Does
A partial release of lien removes the mortgage lien from the specific parcel being sold while leaving the lien intact on the land you keep. Without it, no title company will close the sale because the buyer can’t take clear title.
The process depends on who holds or backs your loan. For loans owned by Fannie Mae, you submit Form 236, Fannie Mae’s standardized application for a partial release.2Fannie Mae. Form 236 Partial Release Request FHA loans follow a separate process under HUD rules.3HUD. Chapter 11 Partial Release of Security Portfolio lenders and other investors set their own requirements. The underlying question is the same across loan types: will the remaining property still adequately secure the debt?
Will You Qualify
Lenders don’t rubber-stamp these requests. For Fannie Mae loans, the mortgage must be current and must have been originated more than 12 months before the request. The release can’t jeopardize the lender’s lien priority, and the remaining property must still have access to a public road.4Fannie Mae. Evaluating a Request for the Release, or Partial Release, of Property Securing a Mortgage Loan If the request fits all eligibility rules, the servicer can approve it on Fannie Mae’s behalf; borderline cases get forwarded to Fannie Mae for case-by-case review.
Other lenders set their own thresholds, but at minimum expect them to require that your loan is in good standing and that the remaining land makes sense as standalone collateral.
The LTV Analysis
The core question is whether the remaining property, after the parcel is removed, still provides enough security. That gets answered through a loan-to-value calculation.
Fannie Mae uses 60% as the benchmark. If the post-release LTV is below 60%, the servicer can approve 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 somewhat more lenient. Under HUD guidelines, no principal reduction is required if the post-release LTV is 75% or less. Above that threshold, the balance must come down enough to get back inside the limit.3HUD. Chapter 11 Partial Release of Security
The lender will also check whether the remaining parcel works on its own. That means zoning compliance, road access, and the general character and utility that made it good collateral when you borrowed. Reviews typically take several weeks, and longer if the servicer has to escalate.
What You’ll Need to Submit
The application package is heavier than most people expect.
- A completed partial release application. For Fannie Mae loans, that’s Form 236; other lenders use their own forms.
- A new property survey from a licensed surveyor showing the dimensions of 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 what remains after. Some lenders order these; others accept borrower-provided appraisals from approved appraisers.3HUD. Chapter 11 Partial Release of Security
- A fully executed purchase agreement for the parcel being sold.
You pay for the survey and appraisals out of pocket. A straightforward boundary survey on a small lot might run a few hundred dollars; a large rural parcel with complex boundaries can cost thousands. Appraisal fees add several hundred more. These costs are non-refundable even if the lender ultimately declines.
What Happens to the Money
Don’t plan on walking away with the full sale price. If your LTV sits at or above the critical threshold, the lender will require enough of the proceeds to go directly toward principal to meet the LTV target.4Fannie Mae. Evaluating a Request for the Release, or Partial Release, of Property Securing a Mortgage Loan In some situations that can mean the entire net proceeds go to the lender.
Even when LTV is comfortably low, many servicers still require some portion of the proceeds to be applied to the balance as a condition of approval. The specific terms land in the partial release agreement. The upside is that your monthly payment often stays the same while the balance drops, so you finish the loan sooner.
If the Lender Says No
Denials happen, especially when the remaining property barely covers the loan or when the parcel you want to sell carries a large share of the total value. A few options:
- Pay down the balance first. If the problem is LTV, a lump-sum principal payment before reapplying can change the math.
- Refinance. A new, smaller loan on just the portion you intend to keep can free up the other parcel. This only works if you qualify for a new loan and the remaining land appraises high enough.
- Ask about conditional approval. Some lenders will say yes with strings attached, such as applying 100% of the proceeds to the mortgage.
- Wait. Time, appreciation, and regular payments all improve your LTV. A request that fails now might succeed in a year or two.
There is no legal mechanism to force a partial release. The lender can refuse, and your only recourse is to satisfy the mortgage in full or improve the collateral picture.
Local Zoning and Subdivision Rules
Lender approval is only half the battle. Your local government regulates land division through zoning codes and subdivision ordinances, and the requirements vary enormously by jurisdiction.
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 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; smaller residential lots almost always require planning department approval and a recorded plat map.
Access is where people get caught off guard. If the parcel you’re selling has no direct connection to a public road, you’ll need to create and record an access easement across your remaining land. Courts generally recognize an easement by necessity when a sale leaves a parcel landlocked, 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 remove the ambiguity.
Utility easements deserve the same treatment. If water, sewer, or electrical lines serving your remaining property run through the parcel you’re selling, record easements preserving your right to maintain those lines before the sale closes, not after.
Taxes on the Sale
Selling land triggers a taxable event, treated the same as any other capital gain or loss. The closing agent files Form 1099-S reporting the gross proceeds.5Internal Revenue Service. Instructions for Form 1099-S (04/2025)
Allocating Cost Basis
To calculate your 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: the fair market value of the sold parcel divided by the fair market value of the entire tract at the time you purchased it.6Internal Revenue Service. Publication 551 Basis of Assets The difference between that allocated basis and the sale price is your capital gain.
If you’ve owned the land for more than a year, the gain qualifies for long-term capital gains rates, which for 2026 are 0%, 15%, or 20% depending on taxable income. Most taxpayers land in the 15% bracket. High-income sellers may also owe the 3.8% net investment income tax on top.
The Home Sale Exclusion
If the land surrounds your primary home, you might wonder about the Section 121 exclusion. 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 allow the exclusion to apply to adjacent vacant land sold separately 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 walk through whether your situation qualifies.
Closing and Recording
Once you have the signed partial release and any required local approvals, a title company or real estate attorney typically handles closing. Several documents get recorded with the county: the new deed transferring the sold parcel to the buyer, the lender’s partial release removing the mortgage from that parcel, and, if a new lot was created, the approved subdivision plat map.
Recording fees are generally modest. The larger closing costs are the title search and insurance on the new parcel, any transfer taxes, and attorney or escrow fees. Confirm in the purchase agreement who pays what. Make sure the partial release records at the same time as the deed; if the deed records first without the lien release, it creates a title cloud that’s fixable but a hassle for everyone involved.
