What it means
The process begins with unpaid property taxes. The local government places a lien, and in many places it sells the lien to an investor, who pays the overdue tax and earns interest if the owner repays.
Owners are normally sent several notices before the lien is sold. If the owner still does not pay, the holder of the lien can start foreclosure proceedings after a waiting period.
The rules differ widely, with some places using a court process and others using an administrative one. Each step must follow the notice rules exactly, or the foreclosure may be set aside.
Before the property is lost, the owner usually has a right of redemption. This lets them repay the tax, interest and costs within a set window and keep the property, and many owners do so after the formal notice arrives.
The amount needed grows over time because interest and costs are added. If the window passes without payment, the property can be sold or the deed passed to the lien holder.
The former owner then loses their rights, and any value above the debt may be returned to them in some systems. Because rules differ, anyone buying at this stage should confirm the title carefully.
For investors, the appeal is the interest return on the lien certificate and, rarely, the property itself. For owners, the lesson is that small unpaid tax bills can snowball into the loss of a valuable asset.
The investor's income therefore depends mostly on interest rather than on winning property. The nuance is that foreclosure is a last resort, and most liens are paid off well before it begins.
An investor buying liens in the hope of obtaining property is relying on an uncommon outcome. A careful investor will check the condition and value of the property before buying a lien.
In practice
Real-world examples.
Example
A county sells a lien on a vacant lot for $3,500 in unpaid taxes. The owner has moved overseas and ignores the notices. After the redemption period ends, the lien holder starts foreclosure and takes the lot. The investor then pays legal fees and ends up with a plot that is hard to sell.
Example
A restaurant owner owes property tax on the building his business occupies. When the lien is sold, a letter arrives from an investor announcing foreclosure if the debt is not paid. He pays the amount plus interest and keeps the building. The investor accepts the payment, and the lien is released.
Example
A retired homeowner misses taxes after a health crisis, and the local government begins foreclosure. A family member discovers the notice, pays the arrears, and the process stops. The case shows how deadlines and notices decide the outcome. In the end, the lien holder receives the interest and the home stays in the family.
Formula
Calculation
Redemption amount = Lien amount x (1 + Interest rate x Years) + Costs
Suppose an investor buys a tax lien for $5,000 and the legal interest rate is 12% simple per year. The owner redeems after 1.5 years, and the investor is also entitled to $300 of costs. Interest = 5,000 x 0.12 x 1.5 = $900. Redemption amount = 5,000 + 900 + 300 = $6,200, so the investor earns $1,200 on a $5,000 outlay.Case study
Seen in the real world.
Tideway Land Partners is an illustrative, fictional investor that buys tax liens on small parcels, expecting most owners to repay with interest. Over several years, it bought 80 liens averaging $4,000 each and collected interest on nearly all of them.
On three parcels, the owners never repaid, and the firm began foreclosure. The legal costs ran to $6,000 per parcel, and one parcel proved to have environmental contamination that made it nearly worthless.
In this illustrative story, the investor's overall return was good, but the foreclosed parcels were the weakest part of the portfolio. The firm changed its approach to check every parcel before buying a lien.
Watch out
Common mistakes.
- Assuming foreclosure is the usual outcome, when most owners redeem and the lien holder just earns interest.
- Ignoring legal and holding costs, which can exceed the debt on small parcels.
- Overlooking the redemption period, which gives the owner the chance to reclaim the property.
Questions
People also ask.
Does the owner lose all equity in foreclosure?
It depends on local law, since some places return surplus above the debt and others do not.
How long does the process take?
It can take months or years, depending on the notice periods and whether the process goes through a court.
Is a lien holder guaranteed to get the property?
No, the owner can redeem until the deadline, and other claims may take priority.
