You need to research this in your county. If you cannot get a clear title search you may not be able to sell the property if the buyer cannot get title insurance. You can get a clear title but it can cost you thousands of dollars more than you would want to pay. Usually the county has to run an ad in the state paper in your area on all property up for tax sale. Contact your local paper and see when they will run the ad. You can also contact your county office and someone there should be able to give you a date. The home owner does have 12 months to pay the taxes in our area in S.C. but you would be paid the interest on that the amount they owe if they pay the taxes.
