Over-the-Counter Tax Liens: The Hidden Market Individual Investors Can Actually Win
TL;DR
- →Over-the-counter (OTC) tax liens are certificates that didn't sell at the main county auction - usually because no bidder wanted them.
- →They're available in Florida, Arizona, Colorado and several other states, sold directly from the county at face value with no bidding competition.
- →The advantage: you get the full statutory rate instead of bidding it down. The risk: these liens didn't sell for a reason - worthless land, contamination, or title problems.
- →Most OTC inventory is garbage, but the good ones exist, and individuals have a real shot because institutional buyers already passed.
What Are Over-the-Counter Tax Liens?
When a county holds its tax lien auction, not every certificate sells. Some properties attract zero bidders - a remote parcel of Arizona desert, a Florida lot with no road access, or a property the whole room knows is over-assessed. Those unsold certificates don't disappear; in many states the county offers them over the counter, meaning you buy them directly from the treasurer's office (or an online portal) at face value plus accrued interest, with no bidding war. Understanding why a lien went OTC is the first step: no bidders, over-assessment, remote or inaccessible land, environmental contamination, title defects, or institutional screening. The honest truth is most OTC inventory is garbage - but because institutional buyers with automated tools already passed, you compete against a much smaller pool of locals and individuals.
Which States Offer OTC Liens
OTC availability varies widely. Florida is the OTC king - counties like Broward, Miami-Dade, Polk, and Hillsborough maintain active year-round lists, some published online. Arizona (Maricopa and Pima have online portals) and Colorado also offer them, while New Jersey doesn't (unsold liens stay with the municipality).
| State | OTC? | Online Access | Statutory Rate |
|---|---|---|---|
| Florida | Yes - year-round | Partial (some counties) | 18% |
| Arizona | Yes | Yes (Maricopa, Pima) | 16% |
| Colorado | Yes | No - call or visit | 9% + Fed discount rate |
| Illinois | Varies by county | Rare | Up to 18% |
| Indiana | Yes | No - call directly | Varies |
| Nevada | Yes | No | Varies |
| New Jersey | No | N/A | N/A |
How to Find and Screen OTC Liens
Finding OTC liens takes more legwork than an auction. Identify target counties (larger counties have more inventory but more competition; smaller rural counties have fewer but sometimes better deals). Contact the treasurer or tax collector and request the current OTC inventory - ask if they call it a struck-off list or resale list, and confirm the purchase process, payment methods, and registration requirements. Then screen ruthlessly: for every certificate verify property type, location (paved road? flood zone?), assessed vs market value, ownership (deceased? multiple owners? bankruptcy?), prior liens (IRS, code violations, municipal assessments), and environmental risk. OTC liens demand more due diligence, not less, because the market already rejected the property once. Buying based on the list alone - without researching the property - is the single biggest OTC mistake.
| Factor | OTC | Live Auction |
|---|---|---|
| Interest rate | Full statutory rate | Often bid down to 0-5% |
| Competition | Low - individuals and locals | High - institutions dominate |
| Property quality | Mixed - many duds, some gems | Higher average quality |
| Due diligence time | Ample - research first | Limited - pre-auction only |
| Inventory | Year-round | Seasonal (1-2/year) |
The Treasure-Hunt Reality: A $500 Lien That Worked
OTC investing is a treasure hunt through a landfill - the average list is 80-90% garbage: swamp land, waterless desert parcels, dying-town commercial lots, and properties with $200 in back taxes and $80,000 in code liens. But buried in it are certificates paying 12-18% with no competition. James, a part-time Denver investor, called a rural Colorado treasurer three months after the auction and got a 47-certificate PDF. Most were access-less mountain parcels, but one was a 0.3-acre lot on a paved road with visible water and sewer, assessed at $18,000 (comps $12,000-$15,000), owned by an out-of-state heir. The lien was $512 at an effective ~14.25%. He bought it, and eight months later a title company handling the heir's other sale flagged the delinquent taxes; the heir paid to clear it. James netted $48.72 on $512 - a 14.25% annualized return for three hours plus one drive. The winners aren't the biggest bankrolls; they're the ones willing to make calls, read 500-line lists, and say no 49 times out of 50.
Frequently Asked Questions
What does over the counter mean in tax lien investing?↓
OTC tax liens are certificates that did not sell at the county's main auction. Afterward many counties make these unsold certificates available for direct purchase from the treasurer's office, usually at face value with no bidding competition.
Which states sell over-the-counter tax liens?↓
Florida, Arizona, Colorado, Illinois (varies by county), Indiana, Nevada, and Iowa (limited) are among them. Availability and process vary by county, so always call the county treasurer directly.
Are OTC tax liens a good investment?↓
They can be, but most OTC inventory is low-quality. The advantage is no bidding competition and full statutory rates; the risk is these liens didn't sell for a reason. Success requires rigorous due diligence.
Do OTC liens earn the same interest as auction liens?↓
Yes, and often the advantage is you get the full statutory rate because there's no bidding process driving it down.
What's the biggest mistake investors make with OTC liens?↓
Buying based on the list alone without researching the property. The list gives you the parcel and tax amount - it won't tell you the land is underwater, landlocked, or contaminated.
