Why the bid rate is not your yield

In most lien states the interest rate is bid down at auction: the statutory maximum is the starting ceiling, and bidders compete by accepting a lower rate. So the advertised rate is rarely what you earn. A state minimum floor can protect the yield, especially when a certificate redeems quickly. See realistic tax lien returns for the full picture, and check your state's exact rate and floor before you bid.

Frequently asked questions

What return do tax lien certificates actually pay?
Less than the advertised statutory maximum, in most cases. The maximum is a ceiling that competitive bidding drives down, so effective yields often land in the mid single digits to low teens depending on the state and how many bidders show up. A state minimum floor can lift the yield on a fast redemption.
How does a minimum penalty floor work?
Some states guarantee a minimum return on a redeemed certificate regardless of how quickly it is paid off. Florida, for example, guarantees a 5 percent minimum, except on a 0 percent bid. If your accrued interest at the bid rate is less than the floor, you receive the floor, which can make the annualized yield on an early redemption quite high.
Does an early redemption help or hurt my yield?
It depends on the floor. Without a minimum, earlier redemption means less accrued interest and a lower dollar return. With a minimum floor, an early redemption can produce a high annualized yield because you earn the floor over a short period.
