How a small over the counter tax lien buy actually plays out, worked through a real example
Take a county that keeps a list of certificates nobody bid on at the sale. In many states those can be bought over the counter at the statutory rate with no bidding down, which makes the mechanics easier to see with a small position than at a live auction. Say the list has 61 leftovers. A disciplined pass throws out anything with no structure, anything where the tax bill is under 400 dollars because the fees eat it, and anything without a clean parcel outline on the county GIS. That typically narrows a list of 61 down to single digits fast. Every remaining candidate should get a street view look and a check of the assessor's card. It is common to find that several vacant lots the assessor valued as buildable are actually drainage strips 18 feet wide behind houses, and occasionally one parcel is a burned structure still under a tarp. A reasonable buy from a list like that lands on three older houses in a working neighborhood, taxes between 600 and 950 dollars, owners of record for 12 years or more, total spend around 2,400 dollars including issuance fees. In a typical outcome all three redeem within five to seven months, with interest at the statutory rate coming out to roughly 88 dollars net after fees over that period. That is closer to a savings account return than a business, and it is worth being honest about that with anyone new to the strategy. The step that matters most for risk: a code enforcement case can be open on a property and not show up until after the purchase, which is why checking the city's code enforcement portal before buying, not after, belongs earlier in the process than most beginners put it. The GIS elimination step is the other one worth keeping, since it typically kills a large share of a list in well under fifteen minutes per parcel.
