How to Use the Tax Lien Yield Estimator
Follow these steps to analyze any tax lien certificate in under 2 minutes.
Enter the lien face value
This is the amount of delinquent taxes. You'll find it in the county auction listing — it's what you'd pay if you won the lien at face value with no premium.
Add any premium paid
In states like Maryland or NJ that use bid-up-the-premium auctions, investors pay more than face value to win. Enter 0 if you're in a bid-down-the-rate state (Florida, Illinois). The premium typically is not returned when the owner redeems.
Set the statutory rate and redemption period
Enter the interest rate set by state law and how long you expect to hold the lien before the owner pays. Most residential liens redeem in 1–18 months. Some never do.
Model the deed scenario
Enter the property's estimated market value and your expected legal/foreclosure costs. The tool shows you whether going to deed would be profitable if the owner never redeems — this is your downside protection analysis.
Example: Florida County Auction
Here's a real example from a Hillsborough County, FL auction (bid-down to 7.25%):
Lien Face Value
$3,500
Premium Paid
$0 (bid-down state)
Rate Won at Auction
7.25%
Expected Redemption
8 months
Interest Earned
$169
Annualized Yield
10.9%
Property LTV
4.1%
At 7.25% (bid down from 18%), this lien still yields ~10.9% annualized because the 8-month hold compounds the return. Property value of $85,000 provides a strong collateral cushion.
