A mortgage is a loan procured by a buyer to pay off the seller of a piece of property in full. The buyer then owes the lender the total amount borrowed, plus interest and fees. As collateral or guarantee of payment, the lender holds the deed or ownership of said property, until the buyer pays the mortgage off. However, the buyer occupies the property as if it were already his or her own. There are several types of mortgage loans available, and which is best for a particular buyer depends on his or her financial situation and long term plans. Some people plan to stay in a house for 30 years; others make short-term investments to move up the real-estate ladder. Matching the right client with the right loan requires time and energy on the part of buyer and lender both. A few of the common terms associated with mortgage loans are closing fees, points, and the annual percentage rate (APR). These and many other fees can be negotiated. The best-looking mortgage advertisement isn't always the cheapest due to possible hidden fees. Experts say comparing the APR of a loan can help the buyer determine which is less expensive, as law requires that all fees be included in this calculation. Often the APR is not advertised and the buyer must ask for this information.
