There are three legal ways to own an abandoned house: buy it at a tax sale, buy it directly from the legal owner, or claim it through adverse possession after years of open, continuous use. Every other approach, including simply moving into a vacant property, is criminal trespass. The path that fits you depends on how quickly you want the title, how much cash you have, and how much risk you’re willing to accept sight unseen.
Moving In Is Not a Shortcut
A house that looks forgotten is still owned by someone in the eyes of the law. Occupying it without authority is criminal trespass in every state, typically a misdemeanor but escalating if you damage the property, refuse to leave, or are armed. In some jurisdictions, repeat offenses or entry into certain structures can rise to a felony.
Adverse possession, discussed below, is a civil doctrine, not a defense to criminal charges. You can be arrested and prosecuted for trespass while you’re building the very case that might one day support an ownership claim. Until a court actually rules in your favor, the law treats you as a trespasser.
Find Out Who Owns It and What’s on the Title
Every path starts with the same research. The county tax assessor’s office lists the current owner’s name, their last known mailing address, and the tax payment history. A long stretch of unpaid taxes is one of the strongest signs that an owner has walked away.
The county recorder of deeds is the next stop. Records there show mortgages, judgments, liens, and easements. A vacant-looking house carrying a large mortgage is a very different proposition from one that’s free and clear.
County records catch the obvious problems but miss the buried ones. A professional title search traces the full chain of ownership and can surface unrecorded interests, unknown heirs, and federal tax liens. Expect to pay $250 to $600 for one, and get it before you commit money to any acquisition method. The title company’s preliminary report tells you what you’re actually walking into.
Buying at a Tax Sale
When property taxes go unpaid long enough, the local government sells the property to recover what it’s owed. This is the most common way genuinely abandoned houses change hands, and it moves much faster than adverse possession. Depending on the state, tax sales take one of two forms.
Tax Lien Sales
In a tax lien sale, you don’t buy the house. You buy the government’s claim to the unpaid taxes. If the owner repays you within the redemption period, you collect the debt plus interest, which can run anywhere from about 8% to as high as 36% depending on the state. If they don’t repay, you can foreclose and take the property.
Tax Deed Sales
A tax deed sale auctions the property itself. Winning bidders receive a deed transferring ownership. Auctions are publicly advertised, bidders register in advance and post a deposit, and the minimum bid is typically the total of back taxes, interest, and administrative costs. In 2023, the U.S. Supreme Court held that a government cannot keep sale proceeds above the tax debt owed; the former owner has a constitutional right to any surplus equity.1Supreme Court of the United States. Tyler v. Hennepin County, No. 22-166
Redemption Periods
Most states give the former owner a window to reclaim the property after a tax sale by paying what they owe plus interest and fees. These redemption periods run from six months to five years. During that window, the former owner can unwind the sale. Don’t spend money on renovations until the redemption period has expired.
The Federal Redemption Wildcard
If the former owner owed federal taxes and the IRS had recorded a lien, the federal government has its own right to redeem the property within 120 days of the sale or the period allowed under local law, whichever is longer.2Office of the Law Revision Counsel. 26 USC 7425 – Discharge of Liens The IRS uses this power when it believes the property sold for less than fair market value and federal taxes remain unpaid. A title search before the auction is the only way to spot this in advance.
You Are Buying Blind
Tax sales are almost always as-is. No warranties, no disclosures, and usually no interior inspection before you bid. You might be getting a structurally sound house that needs cosmetic work. You might be getting a collapsing roof, mold behind every wall, and an underground oil tank that costs tens of thousands to remediate. At minimum, drive by the property and pull any recorded code violations before the auction.
Buying Directly from the Owner
If you can locate the legal owner and they’re willing to sell, this is the simplest route. Start with the name and last known address from the tax assessor’s office. Send a certified letter expressing your interest. Owners of long-neglected houses are often eager to sell, especially when they’re still liable for property taxes on a place they’ve given up on.
If the letter goes unanswered, a professional skip tracer can search databases to locate the owner. Skip tracing fees usually run $20 to $350 depending on complexity. Once you make contact and agree on a price, the deal closes like any standard real estate purchase: purchase agreement, title company, deed transfer. Because the property has likely been neglected, expect the price to reflect its condition and the cost of rehabilitation.
Adverse Possession
Adverse possession lets someone gain legal ownership through long-term, open use without the owner’s permission. It works. It also takes years and carries criminal trespass risk the entire time. Statutory periods range from as few as five years to as many as 30, with most states falling between seven and 20.3Justia. Adverse Possession Laws: 50-State Survey
To succeed, your possession must satisfy every one of these elements:
- Hostile: You occupy the property without the owner’s permission. If the owner ever gave consent, the clock resets.
- Actual: You physically use the property, maintain it, and treat it as your own.
- Open and notorious: Your occupation is obvious to anyone looking, including the legal owner. A secret occupation defeats the claim.
- Exclusive: You don’t share control with the owner or the general public.
- Continuous: Possession is unbroken for the full statutory period in your state.
Meeting every element for the full period gives you the right to file a lawsuit asking a court to recognize your ownership.3Justia. Adverse Possession Laws: 50-State Survey Until the court rules, you don’t own anything.
Color of Title
Some states shorten the required period if you hold “color of title,” meaning a written document that appears to transfer ownership but is actually defective. A deed from someone who didn’t actually own the property, an invalid tax deed, or a flawed court judgment can qualify. With color of title, several states cut the period roughly in half, and your claim can extend to the entire property described in the defective document even if you only physically occupied part of it.
Paying the Taxes
Many states require adverse possession claimants to pay property taxes throughout the statutory period.3Justia.

They’re some of the strongest evidence you’ll have if the claim goes to court.
What It Actually Costs After You Get the Keys
The purchase price is often the smallest expense. What follows can dwarf it.
Environmental Hazards
Older abandoned houses commonly contain lead-based paint, asbestos in insulation, floor tiles, and roofing, and mold that has flourished in the absence of climate control. At a tax sale there’s no seller making disclosures; you inherit whatever is there. Professional remediation for any one of these hazards can easily run into five figures.
Insurance
Standard homeowners policies typically exclude coverage after a home has been vacant for 30 to 60 days. You’ll need a separate vacant-property policy, which generally costs 25% to 50% more than standard homeowners insurance. Not every insurer writes them, and those that do may exclude risks like water damage or vandalism. Lenders on any financed purchase will require the coverage.
Code Violations and Municipal Liens
Municipalities enforce property codes aggressively on abandoned buildings. Fines for overgrown lots, unsecured structures, and building code violations accumulate while a property sits, and in many jurisdictions those fines become liens on the property rather than personal debts of the former owner. Acquire the property and you may inherit the liens along with the obligation to bring the building into compliance. Check with the local code enforcement office and the municipality before you commit.
Structural Rehabilitation
A house left for years without heat, pest control, or roof maintenance deteriorates fast. Water infiltration warps framing and rots subfloors. Pipes burst in freezing climates. Copper plumbing and wiring are frequent theft targets. Get a professional inspection wherever interior access is possible, and assume worst-case scenarios where it isn’t.
Clearing the Title with a Quiet Title Action
After a tax sale or a successful adverse possession claim, you’ll almost certainly need a quiet title action to establish clean, undisputed ownership. This is a lawsuit that extinguishes competing claims from former owners, lienholders, or anyone else who might assert an interest. Without it, you’ll struggle to buy title insurance, sell the property, or borrow against it.
You file a complaint that identifies the property and names every party who might have a claim. Known parties get formal legal notice; unknown parties get notice by publication in a local newspaper. If nobody contests the action, a court enters judgment declaring you the sole owner and that judgment gets recorded. Uncontested cases typically resolve in two to six months. Attorney fees for an uncontested quiet title action generally start around $1,500, with filing fees, publication costs, and service of process adding several hundred more. Contested cases cost and take considerably more.
Once the final order and new deed are recorded, you hold clear, marketable title that can be insured, financed, and sold like any other property.
