Tax Lien Investing: What the Ads Do Not Tell You

You saw an ad promising 18% returns backed by government-secured debt, or you found a county tax sale listing and you are wondering if you can actually make money buying liens on properties you have never seen. Here is the short answer: yes, tax lien investing is real, it is legal, and people do make money at it. But the returns advertised are the ceiling, not the average, and the mechanics of collecting your money are more work than any ad mentions.

What a tax lien actually is

When a property owner does not pay their property taxes, the county is still owed that money. Instead of waiting, most counties sell the debt to investors at a public auction. You pay the back taxes owed, the county gets its cash immediately, and you get a lien against the property plus the right to collect interest and penalties from the owner when they pay it off.

If the owner never pays, in most states you can eventually foreclose and take the property itself. That is the part the ads lead with. It happens far less often than the pitch implies.

How you actually get paid

There are two ways this ends.

The owner redeems the lien. They pay the county (or you, depending on the state) the back taxes plus interest and penalties within a redemption period, usually one to three years depending on the state. You get your capital back plus the statutory return. This is the outcome in the large majority of cases, somewhere in the neighborhood of 95 to 98 out of every 100 liens in most counties, because most people do not want to lose their house over a tax bill and eventually scrape the money together, sell, or refinance.

The owner does not redeem. You file for a tax deed or go through a foreclosure process defined by that state's statute, and if nobody outbids you and no other lienholder gets there first, you can end up owning the property for the cost of back taxes.

A worked example

Say you buy a lien at a county auction in a state with a 12% annual statutory interest rate. The back taxes owed are $4,200. You pay the county $4,200 and receive the lien certificate.

Fourteen months later, the owner sells the house and the title company pays off the lien to clear title. You get your $4,200 back plus 12% annual interest for 14 months, which is $4,200 x 0.12 x (14/12) = $588. Total return: $588 on $4,200, or about 14% for that holding period. Not bad, and it beat a savings account by a wide margin.

Now the version nobody puts in the ad. In a lot of states, the interest rate is not a clean annual rate, it is a flat penalty per redemption period regardless of how long you actually hold it. In Florida, for example, bidding at auction works by investors bidding the interest rate down, so competitive counties can see winning bids as low as 2 to 5%, not the statutory maximum of 18%. You do not get to pick your rate. You get whatever the auction produces, and in popular counties that is often thin.

What people get wrong

They think the advertised rate is what they will earn. The maximum statutory rate (18% in Florida, 16% in Arizona, 24% in Iowa) is a ceiling set by law. In any county where institutional buyers show up with bidding software, competition pushes the actual yield down. You are bidding against people who do this full time with seven-figure budgets.

They do not budget for the liens that go nowhere for years. Some redemption periods run long, and your capital is locked up and illiquid the entire time. Money sitting in a lien earning 4% because that is what the auction produced is money that is not available for anything else.

They skip due diligence on the property. A lien on a $180,000 house is a very different asset than a lien on a landlocked half-acre with no road access or a property with environmental contamination, both of which get abandoned by owners precisely because the land is worthless. You can win a lien at auction on a property that will never redeem and that you will never want to foreclose into, because taking title means taking the liability too. Always pull the parcel record and, ideally, look at it on a map or in person before you bid.

They forget about superior liens. A tax lien usually jumps ahead of a mortgage, but not always ahead of other government liens (IRS liens, municipal code violation liens, other tax liens from prior years). If you end up foreclosing, you can inherit fights you did not know existed. Read the specific priority rules for your state before you assume your lien is first in line.

What to actually do if you are considering this

Start with one county, not five. Pull the upcoming tax sale list, usually published 30 to 60 days ahead on the county tax collector or treasurer website. Cross-reference the parcel numbers against the county property appraiser site to see what you would actually be lending against, assessed value, land use, any existing structures.

Call the county tax collector's office and ask directly: what is the redemption period, is the interest rate fixed or bid down, and what happens procedurally if a lien is not redeemed. Every state runs this differently, and a decent number of county clerks will walk you through it for free because they want the auction to have bidders.

Start small. Buy one or two liens in your first sale, not twenty. Track the actual redemption timeline against what you expected. That single data point tells you more about whether this fits your capital and your patience than any pitch deck will.

The honest limitation

Tax lien investing is not passive and it is not liquid. Your money can sit for a year or more earning a rate you do not control, and if you end up in foreclosure territory you are now a property owner dealing with a physical asset, possibly one with code violations, unpaid utilities, or occupants who need to be dealt with through the legal eviction process in that state. If any of that sounds like more operational work than you want, this is not a "set it and forget it" investment, no matter how the ad frames it.

If you are the kind of investor who is comfortable evaluating a parcel, reading a county statute, and doing the legwork before you bid, tax liens can be a solid piece of a real estate portfolio. If what you actually want is a shorter path to finding and underwriting real deals instead of picking through auction lists blind, Deal Machine is built for exactly that kind of groundwork.
