Buying a house with an encroachment means taking title to land that someone else’s structure is sitting on, and the problem comes with the deed. Depending on what’s crossing the line and how long it’s been there, you could face a lender refusing to close, an appraisal cut, a title you can’t clear when you resell, or a neighbor with a legal claim to part of your lot. Some encroachments are nuisances that a signed agreement puts to rest. Others are the kind of defect that no price discount really fixes. The question to answer before you sign anything is whether this one can be resolved cleanly before closing.
Why Lenders and Appraisers Care
An unresolved encroachment clouds title. That means there’s an open question about who controls part of the land, and that question travels with the property to every future buyer, lender, and insurer.
Lenders are the first wall you’ll hit. Fannie Mae’s guidelines treat only very small encroachments as minor: overhanging eaves or driveways extending a foot or less onto adjoining property with at least ten feet between buildings, and encroachments that are only hedges or removable fences.1Fannie Mae. Title Exceptions and Impediments Anything beyond that can jeopardize mortgage eligibility. Underwriters look at whether the encroachment touches the dwelling, interferes with use of the property, or sits outside what the title policy covers.2PennyMac.

Appraisers may reduce valuation when a boundary dispute exists. The marketability hit is real too. Buyers who learn about an encroachment during their own due diligence often walk, which shrinks the pool and pushes the sale price down. When you eventually sell, you’ll have to disclose the issue to the next buyer, so the discount you accepted going in tends to follow you going out.
The Long-Term Risk: Adverse Possession and Prescriptive Easements
This is where encroachments stop being paperwork and start being permanent. If a neighbor’s structure has been in place long enough, they may have a legal path to claim rights over that strip of your land, and buying the property doesn’t reset the clock.
Adverse possession lets someone gain full legal ownership of another person’s land through prolonged unauthorized use. The required period varies widely by state, from as few as five years in some jurisdictions to twenty or more in others.3Justia. Adverse Possession Laws: 50-State Survey The claimant has to show the possession was continuous, open, hostile (meaning without the owner’s permission), actual, and exclusive. If those elements line up for the full period, a court can transfer ownership of that portion of the parcel.4Legal Information Institute. Adverse Possession
A prescriptive easement is the lighter version. Instead of ownership, the neighbor gains a permanent legal right to use that part of your land for a specific purpose. The elements are similar, but exclusive possession isn’t required, so the original owner can still use the land alongside the easement holder.5Legal Information Institute. Prescriptive Easement
What this means for you as a buyer: find out how long the encroachment has existed and whether the current owner ever gave written permission for it. Written permission defeats both doctrines, because it converts the use from hostile to permissive. If the encroachment has been in place for a stretch that approaches your state’s adverse possession period and no one has documented permission, treat that as a serious red flag rather than a negotiating point.
Confirming What You’re Actually Buying
A boundary survey by a licensed surveyor is the most reliable way to find an encroachment. The surveyor measures the property, marks the legal boundaries with physical monuments, and produces a plat showing whether anything from a neighboring parcel crosses the line. A residential boundary survey typically costs between $1,200 and $5,500, depending on lot size, terrain, and local rates.
Most states do not require a survey before closing. Whether you get one usually comes down to what your lender or title insurer demands. Skipping it to save money is one of the more reliably regrettable decisions in a home purchase, because once you close, the problem is yours.
Sellers in most states are legally obligated to disclose known boundary disputes, and a title search of public records can turn up previously recorded encroachment agreements or boundary issues. Those methods catch what’s already documented. An encroachment nobody has complained about can sit undetected for years until a survey reveals it.
Fixing It Before You Close
The best time to deal with an encroachment is before closing. Once you own the property, the seller has no incentive to help and the neighbor already has their structure in place. The main options, from cleanest to least satisfying:
- Removal of the encroaching structure. The seller negotiates with the neighbor to move the fence, tear down the shed, or reroute the driveway. The problem ends and the title clears. Not always realistic when the structure is expensive or the neighbor is uncooperative.
- Recorded encroachment agreement or easement. A formal easement grants the neighbor a legal right to maintain their structure on your land for a defined purpose. It’s recorded with the county and binds future owners on both sides. It also establishes that the neighbor’s use is permissive, which cuts off any future adverse possession claim.6Legal Information Institute. Easement
- Boundary line adjustment. The property lines are legally redrawn so the structure sits on the neighbor’s parcel. This takes a new survey, a formal agreement between both owners, and recording new deeds. Municipal approval timelines range from a few weeks to several months.
- Price reduction. If the issue can’t be resolved before closing, negotiate a lower purchase price to compensate for the risk and your likely future costs. This doesn’t fix the problem; it just gives you a financial cushion for dealing with it later.
What Resolution Costs and Who Should Pay
Costs stack up faster than buyers expect. A boundary survey is $1,200 to $5,500. Real estate attorneys handling boundary work typically charge $150 to $500 per hour, and a dispute that needs negotiation or document drafting can push legal fees past $2,000. Deed recording fees vary by county and are generally modest. Add municipal review time for a boundary line adjustment and the whole process can push closing out by weeks or months.
Build these numbers into your negotiation. If the seller wants to close quickly and resolution takes time, that’s leverage. You can ask the seller to cover survey and legal costs, hold funds in escrow until the issue is resolved, or cut the price by an amount that reflects your anticipated expenses.
What Title Insurance Will and Won’t Cover
Title insurance protects owners and lenders from financial loss caused by title defects, but standard policies have a real gap on encroachments. A standard owner’s policy typically carries an exception for anything that would be disclosed by an accurate survey of the land. If a survey would have caught the problem, the standard policy won’t pay.
To close that gap, you can request an extended coverage policy or a specific encroachment endorsement. The ALTA 28 series of endorsements is designed for this, covering losses related to encroachments, boundary issues, and easement violations. Getting one usually requires a recent survey and an additional premium. If the neighbor later asserts a claim, demands removal, or challenges the boundary, that endorsement is the difference between a covered loss and paying out of pocket.
One detail buyers routinely miss: the lender’s title policy protects the lender, not you. An owner’s policy is a separate purchase. Buying a property with a known encroachment without an owner’s policy that covers encroachments means you’re absorbing the full financial risk yourself.
Protecting Yourself in the Purchase Contract
Your purchase agreement is your strongest tool. A survey contingency gives you the right to walk away or renegotiate if the survey turns up boundary issues you didn’t expect. Without one, finding an encroachment after you’re under contract leaves you with a bad choice between closing with the problem and losing your earnest money.
If an encroachment is already known when you make your offer, write the fix into the contract. Name the responsible party, set a deadline, and define what happens if the deadline passes. Language like “seller will work to resolve boundary issues” is essentially unenforceable. The contract should state the specific remedy: removal, recorded easement, boundary line adjustment, or price reduction by a stated amount.
Deciding Whether to Go Through With the Purchase
Not every encroachment carries the same weight. A fence six inches over the line is a different animal from a neighbor’s garage sitting on your lot. Three questions do most of the work.
How bad is the physical intrusion? If it affects a thin strip of unused side yard, the stakes are low. If it blocks a future addition, pool, or driveway you actually care about, no discount will feel like enough in five years.
How bad is the legal exposure? How long has the encroachment existed, is the neighbor cooperative, and has anyone signed a written agreement establishing permission? A longstanding, undocumented encroachment with a hostile neighbor is a far riskier proposition than a recent one with a cooperative neighbor willing to sign an easement.
Does the proposed fix actually resolve anything? A recorded easement or a boundary line adjustment gives you legal certainty. A price reduction gives you cash and leaves the problem in place for the next sale. If the only concession on the table is a modest discount with no legal resolution, you’re buying someone else’s title problem at a slight discount, and you’ll be the one disclosing it the next time around.
