Tax delinquent properties for sale in NH are handled town by town, not through any statewide system. Each municipality’s tax collector maintains its own list of unpaid taxes, active liens, and properties that have been deeded to the city or town and authorized for sale. To find and buy one, you’ll work directly with individual tax collectors, watch for auction notices, and accept that the title, occupancy, and environmental risks on these properties are real.
Where to Find the Listings
Start with the tax collector’s office in whatever town or city interests you. Most municipalities post delinquency information on their official websites under the tax collector or finance department page. Rochester keeps a dedicated page for impending tax deeds and auctions.1City of Rochester, New Hampshire.

Unpaid Taxes, Tax Liens, and Deeding
State law requires that notice of a pending lien or sale be published in a local newspaper at least three weeks before the event. Smaller towns may still post physical notices at the town hall or local post office. Many municipalities also contract with auction firms that run dedicated websites listing upcoming tax-deed auctions across multiple towns and counties.
There’s no single state portal that aggregates every New Hampshire municipality’s delinquent list. With more than 230 municipalities, searching broadly means visiting individual town and city websites or calling tax collectors one by one.
What a Listing Tells You
A standard delinquent property listing identifies each parcel by the current owner’s name, the map and lot number used for assessment, and the street address. The map and lot number is the official identifier. Street addresses may be informal or absent, especially for undeveloped land.
Financial details show the total amount owed: the original tax levy, accumulated interest, and any costs the municipality incurred during the lien process. Listings also indicate whether a property is still in the lien stage or has already been deeded to the municipality. That distinction matters because only deeded, sale-authorized properties are actually available to purchase.
When a Property Is Actually Available to Buy
Appearing on a delinquent list doesn’t mean a property is for sale. Under New Hampshire’s tax-deeding process, an owner who falls behind has two years to redeem the lien, after which the tax collector sends a final certified notice to the owner and any known mortgage holders at least 30 days before executing a tax deed.3New Hampshire General Court. New Hampshire Code 80:77-a – Notice to Mortgagees Only after that deed is executed does the town or city own the property.4New Hampshire General Court. New Hampshire Code 80:76 – Tax Deed
Ownership alone doesn’t put the parcel on the auction block. Under RSA 80:80, the municipality must authorize sale through a majority vote at the annual town meeting or, in cities, through a city council vote.5New Hampshire General Court. New Hampshire Code 80:80 – Transfer of Tax Lien Some towns pass standing authorizations each year; others vote parcel by parcel. Until that vote happens, a tax-deeded property sits in municipal ownership and cannot be purchased.
How the Sales Work
Once a sale is authorized, municipalities typically run either a public auction with live bidding or a sealed-bid process where written offers are opened at a public meeting. Many hire professional auction firms to manage the event.
Registration requirements and deposit amounts vary by municipality and auctioneer. Expect to show government-issued identification, provide a deposit (commonly a certified or cashier’s check), and complete registration forms before receiving a bidder number. If you’re bidding under a business entity, bring your federal tax identification number and organizational documents.
Winning bidders usually must pay the balance within a very short window, often 24 to 48 hours depending on the municipality’s terms.
The Former Owner’s Three-Year Right to Repurchase
This is where many buyers get caught off guard. Even after a municipality takes a property by tax deed, the former owner has up to three years from the date the deed is recorded to repurchase it. The former owner sends notice of intent by certified mail and then tenders all back taxes, interest, costs, and penalties within 30 days of that notice.6New Hampshire General Court. New Hampshire Code 80:89 – Notice to Former Owner and Opportunity for Repurchase
If the municipality hasn’t yet sold the property when the former owner exercises this right, the repurchase goes through at cost rather than market value. Any property you buy at a recent tax-deed auction carries some risk that the former owner could initiate repurchase if the statutory period hasn’t expired. Ask the municipality for the exact date the tax deed was recorded, and factor that timeline into your plans before bidding.
What the Deed Gives You, and What It Doesn’t
A tax deed in New Hampshire is not a warranty deed. These sales typically convey a “deed without covenants,” meaning the municipality makes no promises about title quality. The town transfers whatever interest it acquired through the tax-deeding process, with no guarantee the title is clean or free from competing claims.
Title insurance is a particular headache. Whether an insurer will write a policy depends on the company and the specific property. Some are more willing than others, and many will not insure a tax-deed title until well after any statutory challenge period has expired. If you need title insurance, and you almost certainly do for any property you plan to finance or resell, talk to a title company or real estate attorney before the auction, not after.
Mortgages and the Risk of Notice Errors
A properly executed tax deed transfers ownership in fee simple and extinguishes outstanding mortgages. Tax liens hold priority over mortgage liens, so a bank’s mortgage gets wiped out when the municipality takes the property.7New Hampshire Municipal Association. Don’t Let Sneaky Errors Sabotage Tax Deeds That’s why mortgage holders receive certified notice at the lien and pre-deeding stages: they get a chance to protect their interest by paying the delinquent taxes.
The catch: this only works if the municipality followed the notice requirements correctly. If the tax collector failed to notify a mortgage holder as required under RSA 80:77-a, the deed may be ineffective against that mortgagee, leaving the lien intact on the property. Procedural errors in tax-deeding are not rare, and they can leave a buyer holding a property with an unextinguished mortgage. Have a real estate attorney review the tax-deed history before you commit money.
Costs Beyond the Hammer Price
- Real estate transfer tax. New Hampshire imposes a transfer tax on both buyer and seller at $0.75 per $100 of the sale price (equivalent to $7.50 per $1,000). On a $50,000 purchase, that’s $375 from your side alone.8NH Department of Revenue Administration. Real Estate Transfer Tax
- Recording fees at the county Registry of Deeds. These vary by county but run around $12 for the first page and $4 per additional page in some counties.
- Title search and legal fees. Given the title risks, a thorough search and attorney review is money well spent.
- Property taxes going forward. The moment you own the property, you owe current and future taxes.
If Someone Is Still Living There
Buying a tax-deeded property does not let you walk in and change the locks. If the former owner or a tenant remains, New Hampshire law requires you to go through the formal judicial eviction process under RSA Chapter 540. Self-help evictions, including changing locks, shutting off utilities, removing belongings, or arranging a physical removal without a court order, are illegal.9New Hampshire Judicial Branch. Landlord/Tenant – District Division
The process starts with a written eviction notice. For nonpayment, a 7-day notice is required; for other grounds, 30 days. After the notice expires, you file a landlord-tenant writ with the court, have it served by a sheriff, and wait for a hearing. If the occupant contests the eviction, the hearing must be scheduled within 10 days. Only after a court order issues, and any appeal period runs, can you lawfully take possession. The process can run weeks or months. Build the time and legal costs into your plan when a property looks occupied.
Environmental Exposure
Municipalities themselves can refuse a tax deed under RSA 80:76 if accepting it would expose the town to environmental liability such as contamination cleanup, hazardous waste, or underground storage tanks.4New Hampshire General Court. New Hampshire Code 80:76 – Tax Deed When a town refuses, the property never enters municipal ownership and never reaches auction through this process.
For properties that do reach auction, that environmental risk transfers to you. A municipality selling with a no-covenants deed makes no representations about contamination. Buy a former gas station or industrial parcel and discover contamination afterward, and you may be on the hook for cleanup under state and federal environmental law. For any commercial or industrial property on a tax-deed list, order an environmental site assessment before bidding.
