How Redemption Timing Affects Your Real ROI on Tax Liens

When investing in tax liens, the statutory interest rate is only one piece of the puzzle. The actual time it takes for the property owner to pay off their delinquent taxes—known as the redemption period—has a massive impact on your true annualized return. Understanding how time works for (or against) you is critical to accurately projecting your profits.

The Core Concept: Time vs. Capital Deployment

Tax liens accrue interest over time, usually calculated monthly or annually depending on the state. If you buy a lien with an 18% annual interest rate, you only earn that full 18% if the lien is held for exactly one year. If it redeems in one month, you earn 1.5% (18% ÷ 12 months).

While earning 1.5% in a single month is still an 18% annualized pace, the problem arises when you factor in premium bids and idle capital. When a lien redeems quickly, your capital is returned to you, and it stops earning interest until you can deploy it into a new investment.

A Simple Example

Why Early Redemption Can Hurt

Many investors cheer when a property redeems quickly because they get a fast check in the mail. However, institutional investors actually prefer liens that season for 12 to 24 months.

Every time a lien redeems, you face reinvestment risk. You have to wait for the next county auction, research new properties, and compete against other bidders all over again. During that waiting period, your cash is sitting in a bank account earning standard savings rates, dragging down your blended portfolio yield.

What Counts as a "Good" Tax Lien ROI

There is no single right number — your target depends on your effort, liquidity needs, and the alternatives you are comparing against. A practical frame many investors use:

• 12%–18%+ annualized (Strong): well above most fixed-income alternatives; usually requires less competitive counties or favorable redemption timing.
• 8%–12% annualized (Solid): a reasonable target for disciplined bidding after accounting for premiums and reinvestment drag.
• 5%–8% annualized (Marginal): barely above low-effort alternatives like CDs; the administrative work and illiquidity may not be justified.

These tiers are guidelines, not guarantees. A flat-penalty state can produce a very high annualized return on an early redemption but a low return on a late one, while a premium-bidding state can produce a net loss on an early redemption. Compare any tax lien yield to what your capital could earn elsewhere, and remember the return is only realized if the owner redeems.

Use the Calculator

To accurately project your returns, you need to model different redemption scenarios. What happens if the property redeems in 3 months? What if it goes the full 36 months to foreclosure?

Our Tax Lien Bid Calculator allows you to adjust the expected redemption timeline so you can see exactly how time impacts your bottom line before you place a bid.
