Land sold for back taxes
Land whose taxes have been delinquent for three years goes to the county resale, held on the second Monday in June.
What to do: Ask the county treasurer for the resale list in the spring. Parcels on it have been unpaid for years, so read each one closely: there is usually a reason nobody paid.
Septic before you build
Before a new system goes in, the Department of Environmental Quality has to issue an Authorization to Construct. Soil profile tests may only be done by DEQ or a DEQ-certified soil profiler, and percolation tests only by someone registered through the Department of Health.
What to do: Make the offer contingent on a soil profile by a certified profiler. The profile is what decides which systems the ground will take, and the cheap conventional one is not always on the list.
Being taxed as a farm
Agricultural land is assessed on its agricultural use value, by a method the State Board of Equalization approves. Separately, the taxable value of homestead and agricultural property may rise by no more than 3% a year, and other property by no more than 5% -- but the cap does not apply in a year the title changes hands.
What to do: The seller's tax bill may be years of capped increases behind the market. Ask the county assessor for the parcel's fair cash value, not the capped one, and budget your taxes on that.

Old well records
The Oklahoma Water Resources Board publishes the completion reports filed by licensed well drillers: location, depth, construction date and use.
What to do: Look up the neighbours' wells before you look at the listing again. Depth and date tell you what a new well is likely to cost. Wells dug before reporting began, or by owners, will not be there.

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.
