Close Brothers Land Company contributed to a settlement boom in Pipestone County. Land buyers would sign a contract with the Close Brothers or their two other land companies — The Western Land Company and the Southwestern Minnesota Land Company — to purchase property over time. The buyer would get land with a house and barn already built on the property. These sale records are the original contracts signed by buyers. They include the payments due, if transferred to another party, and if the contract was completed. Their office was in Pipestone from 1883 to the late 1890s when their landholdings were sold.
