"I am going to put you to a test." So far, Rand's relatives had failed prior tests by not keeping their agreements. Connie was theoretically looking for a loan, not a gift or a handout. Rand took her at her word and even offered easier terms than Connie requested in exchange for an ironclad promise to repay. Rand obviously knew that there were good odds that as time went by her "loan" would morph into a gift without further clarification up front. How many relationships turn sour when folks do not keep their agreements? Her letter makes sense to me.
