Everything you need to know
about tax sale investing.
Questions answered — from tax liens vs. tax deeds and how bidding works, to due diligence essentials and AI/LLM data access.
Tax sale properties in the US are real estate sold by counties to recover unpaid property taxes. Some states sell tax lien certificates (the investor earns interest until the owner redeems), while others sell tax deeds (the property itself) or redeemable deeds (a deed subject to a redemption penalty). Interest rates (commonly 12–18%), redemption periods, and foreclosure procedures vary by state. Key risks include no interior inspection rights, surviving liens (e.g. IRS), and environmental liabilities. Always do a title search, confirm access, and set a maximum bid before participating.
General
What is a tax sale property in the US?
A tax sale property is real estate sold by a county (or municipality) when the owner fails to pay property taxes. Depending on the state, the county either sells a tax lien certificate (the right to collect the debt plus interest) or a tax deed (the property itself). The minimum bid typically covers the back taxes, interest, and costs — often far below market value — which is why tax sales can offer below-market opportunities.
What is the minimum bid?
The minimum bid (or opening bid) at a US tax sale generally equals the total delinquent taxes, accrued interest, penalties, and the county's administrative and legal costs. Some states add other amounts (for example, Florida adds value for homestead property). No bid below this amount is accepted. Because the minimum is tied to taxes owed rather than market value, winning bidders can sometimes acquire real estate at a steep discount.
What is the difference between a tax lien and a tax deed?
A tax lien sale sells a certificate representing the unpaid taxes; you earn a fixed interest rate (often 12–18%) until the owner redeems, and you can foreclose only if they never redeem. A tax deed sale sells the property itself to the highest bidder. A redeemable deed (e.g. Texas, Georgia) gives you a deed but the owner can redeem within a set period by paying a penalty. See our Tax Deed vs. Tax Lien guide for details.
Can anyone buy a tax sale property in the US?
Generally yes — most states allow any adult or company to participate, though many counties require pre-registration and a deposit, and some require a statement that you owe no delinquent taxes in that county. Foreign buyers can usually participate but should confirm county-specific and tax-withholding rules. Always confirm eligibility and registration requirements with the specific county before bidding.
Which states have the most tax sale activity?
Florida, Texas, Georgia, Arizona, Illinois, New Jersey, Pennsylvania, California, Ohio, and New York are among the most active markets. Tax lien states (AZ, FL, IL, NJ) attract income-focused investors, while tax deed and redeemable deed states (CA, PA, TX, GA) attract those seeking the property. Our platform aggregates listings from counties across all 50 states into one searchable database.
Can I get a mortgage on a tax sale property?
Financing a tax sale purchase is challenging. Most conventional lenders will not lend before you hold clear, insurable title — which can require completing a redemption period and/or a quiet title action. Cash buyers have a major advantage. Some private or hard-money lenders offer bridge financing. Plan to fund tax sale purchases with cash or pre-arranged alternative financing.
Bidding & Process
How does bidding work at a US tax sale?
It varies by state. Tax lien auctions often use bid-down-the-interest-rate (AZ, FL) or premium/penalty bidding (NJ, IL). Tax deed and redeemable deed sales use ascending price bidding to the highest bidder (CA, TX, GA, PA). Many counties now run sales on online platforms (e.g. RealAuction, Bid4Assets, GovEase). Confirm the format and registration rules for each county before bidding.
Is there a redemption period after a tax sale?
It depends on the state and sale type. In tax lien states, owners can redeem during a statutory period (e.g. Florida 2 years, Arizona 3 years) before the lienholder can foreclose. In redeemable deed states, owners can redeem after the sale by paying a penalty (e.g. Texas 6 months–2 years; Georgia 12 months at a 20% premium). In most pure tax deed sales (e.g. California), there is no redemption after the sale.
What interest rate do tax liens pay?
Maximum statutory rates vary by state — commonly 12–18% per year (e.g. Florida and Arizona up to 16–18%, Illinois penalty up to 18% per six-month period). In most states the rate is bid down at auction, so your effective return depends on competition. Redeemable deed states instead pay a fixed penalty (e.g. Texas 25%, Georgia 20%).
What happens if I win the bid?
For tax liens, you pay the amount due and receive a certificate; you earn interest until redemption, and can foreclose if the owner never redeems. For tax deeds, you typically pay immediately (cash or certified funds) and receive a deed; in redeemable deed states the deed is subject to the owner's redemption right. Online auctions usually require a deposit in advance and prompt final payment.
Do I get clear title from a tax sale?
Not automatically. A tax deed usually conveys title subject to certain surviving liens (e.g. IRS liens with their own redemption rights, some municipal or special-assessment liens). To obtain marketable, insurable title, investors often complete a quiet title action after any redemption period expires. Always order a title search and consult a local attorney.
Can the previous owner stay in the property after the sale?
Possibly. Even after you receive a deed, an occupant may remain until you complete the redemption period (where applicable) and pursue eviction under state landlord-tenant or ejectment law. Factor the time and cost of gaining possession into your acquisition plan and budget.
Due Diligence
What due diligence should I do before bidding?
At minimum: (1) Order a title search to identify surviving liens and encumbrances. (2) Check zoning and land-use rules with the county/municipality. (3) Confirm legal access — some parcels are landlocked. (4) Review environmental records. (5) Check for code violations or municipal liens. (6) Research comparable sales to set a maximum bid. (7) If possible, inspect the exterior and street view of the property.
Can I inspect a tax sale property before bidding?
For vacant land, you can typically view the lot from the public right-of-way. For occupied or locked properties, you generally cannot inspect the interior without permission. This is a key risk in tax sale investing — always factor unknown interior condition into your maximum bid and budget a contingency for repairs or remediation.
What liens survive a tax sale in the US?
A tax foreclosure or tax deed generally extinguishes most private liens (including mortgages), but some obligations can survive depending on the state: IRS federal tax liens (with a 120-day redemption right), other governmental or municipal liens, certain special assessments, and some HOA or environmental obligations. Always perform a title search and consult a local real estate attorney.
Are there environmental risks with tax sale properties?
Yes. Properties can have contaminated soil, underground storage tanks, asbestos, or other liabilities, especially former industrial, agricultural, or gas-station sites. Environmental cleanup obligations can attach to the property and become the owner's responsibility. Review county records and state environmental databases before bidding on any commercial or industrial parcel.
How do I find out about existing tenants or occupants?
Review the county assessor and recorder records to understand the property's use, drive by in person to observe occupancy, and check title for recorded leases. Code-enforcement records may reveal complaints or orders. If occupants are present, factor in the cost and timeline of eviction or ejectment under state law.
How do I determine a fair maximum bid?
Start with recent comparable sales (nearby, similar size and type) to estimate market value. Then deduct estimated repair/remediation costs, carrying costs (taxes, insurance, financing, redemption-period holding), and your desired profit margin. The result is your maximum bid ceiling — never exceed it regardless of auction pressure. Many experienced investors target a 30–50% margin of safety below market value.
