Demand Loan
A loan where the balance must be repaid upon request.

Deposit
A sum of money deposited in trust by the purchaser on making an offer to purchase. When the offer is accepted by the vendor (seller), the deposit is held in trust by the listing real estate broker, lawyer, or notary until the closing of the sale, at which point it is given to the vendor. If a house does not close because of the purchaser's failure to comply with the terms set out in the offer, the purchaser forgoes the deposit, and it is given to the vendor as compensation for the breaking of the contract (the offer).
