Real stories from a real investor. No fluff, just what worked and what didn't.
There is no single average. The statutory rate is a ceiling set by state law (Iowa 24% fixed, Florida and New Jersey 18%, Arizona 16%, Kentucky 12%; Illinois sells penalty bids capped at 9% per six-month period, 35 ILCS 200/21-215), and the realized return depends on the bid method, how soon the owner redeems, and your costs.
