Most recent sales data in the Sparr area indicates that a 1 acre tract of land could sell for $43,500 (low) or $48,0000 (high) depending upon location. If one were considering buying or selling tracts of larger sizes, then those amounts would change. Example: A ten acre tract in Sparr could sell for $220,000, in which case the price per acre would be about $22,000. It all depends on the market data and what a buyer and seller agree to at an arms length transaction.

Do you have an agent? If not, there is no way for you to get this information.

As a buyer, you don't pay the commission anyway......So why don't you get an agent and have them bring up all the solds, actives, pendings, expireds and withdrawn properties in that area so you can make an informed decision.
All of us on this forum could do the same thing for you, but we won't be paid for our time. We are giving advice free to the consumer on this forum, but there is still a step at which you can't go beyond.

What you are asking will take hours of research, so go find a good agent in Sparr, one you communicate well with, like and trust, and move forward.
