Before you actually apply for a loan and pay a fee, ask for all the information the lender has on the loan you are considering. It is important that you understand index rates, margins, caps, and other ARM features like negative amortization. You can get helpful information from advertisements and disclosures, which are subject to certain federal standards.

Advertising
Your first information about mortgages probably will come from newspaper advertisements placed by builders, real estate brokers, and lenders. While this information can be helpful, keep in mind that the ads are designed to make the mortgage look as attractive as possible. These ads may play up low initial interest rates and monthly payments, without emphasizing that those rates and payments later could increase substantially. Get all the facts.

A federal law, the Truth in Lending Act, requires mortgage advertisers, once they begin advertising specific terms, to give further information on the loan. For example, if they want to show the interest rate or payment amount on the loan, they must also tell you the annual percentage rate (APR) and whether that rate may go up. The annual percentage rate, the cost of your credit as a yearly rate, reflects more than just a low initial rate. It takes into account interest, points paid on the loan, any loan origination fee, and any mortgage insurance premiums you may have to pay.

Disclosures From Lenders
Federal law requires the lender to give you information about adjustable rate mortgages, in most cases before you apply for a loan. The lender also is required to give you information when you get a mortgage. You should get a written summary of important terms and costs of the loan. Some of these are the finance charge, the annual percentage rate, and the payment terms.

Selecting a mortgage may be the most important financial decision you will make, and you are entitled to all the information you need to make the right decision. Don't hesitate to ask questions about ARM feature when you talk to lenders, real estate brokers, sellers, and your attorney, and keep asking until you get clear and complete answers.
