Unpaid tax bills are sold as certificates at 12 percent, and a farm nobody farms keeps its farm tax only until it is sold.
$5,600 an acre is the average for farm real estate here, against $4,500 nationally (NASS, 2026). Pasture averages $4,050.
Land sold for back taxes
An unpaid tax bill becomes a certificate of delinquency, which earns 12 percent simple interest a year. County clerks sell certificates to private buyers at an annual sale on a statewide schedule, and buyers must register with the clerk at least a week ahead. After a year the holder can sue to foreclose, and has eleven years to do it. If the foreclosure sale brings less than two-thirds of the appraised value, the owner has six months to redeem, paying the price plus 10 percent a year and the buyer's costs, though the buyer takes possession at once. If nobody bids, the master commissioner deeds the land to the certificate holders.
What to do: A certificate is a debt, not land. To buy the land, watch the master commissioner's foreclosure sales, and know that a price under two-thirds of the appraisal leaves the owner six months to take it back.

Septic before you build
Before any construction, the site has to be evaluated by a certified inspector at the local health department, or by a professional engineer, who flags and records the approved area and gives the applicant a drawing of the lateral field and its written limits. Then a construction permit is needed. Only a certified inspector can issue it, only to a certified installer or the homeowner, and it lasts a year.
What to do: Ask the county health department whether the parcel has a site evaluation. If it has none, get one before you close: the approved area it flags shapes where a house can go.

Being taxed as a farm
Ten or more contiguous acres used for livestock, poultry, tobacco or other crops, timber included, are assessed at their farm value, and horticultural land qualifies from five acres; the house, lawn and drive do not count. The property valuation administrator decides whether land qualifies. Land taxed as a farm for five years or more keeps that classification if the owner simply stops farming, but only until it is sold to anyone but a surviving spouse. Land converted to another use is taxed at full value from the next year.
What to do: If the parcel is on a farm assessment but nobody farms it any more, the assessment ends when you buy it. Budget for tax at full value unless you will farm it.

Old well records
The Kentucky Geological Survey's Groundwater Data Repository holds the state's water well and spring records, updated quarterly from the Division of Water: location, use, construction, the rock drilled through and the casing. It can be searched by county, quadrangle or distance from a point.
What to do: Search a radius around the parcel and read the nearest wells for their depth and what the driller found.

Laws change. Check the source before you rely on a date or a deadline, and ask the county office named, because local rules sit on top of these.
