An Installment Sale and Security Agreement in Equipment and Fixtures is a contract between two parties, often a seller and a buyer, that facilitates the sale of equipment or fixtures. The agreement outlines the terms of the sale and the buyer's agreement to repay the seller through installment payments. It also outlines the security interests the seller holds on the equipment or fixtures until the buyer has repaid the full purchase price. Installment Sale and Security Agreement in Equipment and Fixtures can come in two varieties: a true lease or an installment sale. A true lease provides for the seller to retain ownership of the equipment or fixtures, and the buyer to make payments over a period of time in order to use them. An installment sale is similar, but the buyer agrees to make payments over time to eventually purchase the equipment or fixtures.
