If this is a breach of contract, what type of breach and what remedies are available?

Aaron owns property on which he wished to build a commercial building. Aaron entered into a loan agreement with Courtney to provide finances that would support the construction. The loan agreement did not specify the amount of the monthly payments or interest rates. At the urging of Courtney, Aaron tore down valuable existing revenue-generating properties on the land to clear the way for the new construction. Courtney, however, did not come up with the finances, so Aaron sued for breach of contract.
