Adjustable Rate Mortgage (ARM) - A mortgage in which the interest rate is adjusted periodically based on an index. Also called a variable rate mortgage.

Adjustment - For an adjustable rate mortgage, the time between changes in the interest rate charged. The most common adjustment intervals are one, three or five years.

Amortization - Literally to "kill off" (root: mort) the outstanding balance of a loan by making equal payments on a regular schedule (usually monthly). The payments are structured so that the borrower pays both interest and principal with each equal payment.

Annual Percentage Rate (APR)- The interest rate which reflects the cost of a mortgage as a yearly rate. This rate is usually higher than the stated loan rate for the mortgage, because it takes into account points and other charges.

Application Fee - The fee charged by the lender to the borrower for applying for a loan. Payment of this fee does not guarantee that a loan will be approved. Some lenders may apply the cost of the application fee to certain closing costs.

Appraisal - The determination of property value based on recent sales information of similar properties.

Assumable Loan - These loans may be passed on from a seller of a home to the buyer. The buyer "assumes" all outstanding payments.

Balloon Mortgage - Behaves like a fixed-rate mortgage for a set number of years (usually five or seven) and then must be paid off in full in a single "balloon" payment. Balloon loans are popular with those expecting to sell or refinance their property within a definite period of time.

Broker - An individual in the business of assisting in arranging funding or negotiating contracts for a client but who does not loan the money himself. Brokers usually charge a fee or receive a commission for their services.

Caps - A set percentage amount by which an adjustable rate mortgage may adjust each adjustment period. For adjustable loans, caps are usually quoted as two numbers as in 2/6. The first number indicates how much a loan may adjust at each adjustment period while the second number indicates how much a loan may adjust over its lifetime.

Loans like the 3/1 and 5/1 adjustable which have an initial fixed period are quoted with 3 numbers as in 3/2/6 which would mean that the first adjustment may be as much as 3%, subsequent adjustments are capped at 2% each, and the lifetime cap is 6%.

Two-Step loans are quoted with a single cap, which is the amount by which the loan may adjust at its single adjustment date.

Closing Costs - Fees paid by the borrower when property is purchased or refinanced. These typically include a loan origination fee, discount points, appraisal fee, title search, title insurance, survey, taxes, deed recording fee, and credit report charges.  PMI costs are also excluded from this figure. Title Insurance is usually in the range of 25-30 cents per $1,000 borrowed.

Commitment - A written letter of agreement detailing the terms and conditions by which the lender will lend and the borrower will borrow funds to finance a home.

Conforming Loan - A mortgage loan for up to $300,700 in the continental United States (Alaska and Hawaii limits are higher).

Construction Loan - A short term loan for funding the cost of construction. The lender advances funds to the builder as the work progresses.

Conversion - The right of a borrower to convert an adjustable or balloon loan into a fixed loan. The possible options are as follows...

Credit Rating - Borrowers are rated by lenders according to the borrower's credit-worthiness or risk profile. Credit ratings are expressed as letter grades such as A-, B, or C+. These ratings are based on various factors such as a borrower's payment history, foreclosures, bankruptcies and charge-offs.

Credit Report - A report to a prospective lender on the credit standing of a prospective borrower. Used to help determine creditworthiness. Information regarding late payments, Default, or bankruptcies will appear here.

Appraisal, credit report and title search fees are not included in the finance charge calculation.

Fixed-Rate Mortgage - A mortgage where the interest rate does not change for the life of the loan.

Float - Between the time of application and closing, a borrower may choose to bet on interest rates decreasing by electing to float. Floating is essentially choosing not to lock the interest rate. Since it is the borrower's responsibility to lock his or her rate before (or at) closing, choosing to float is considered risky and may result in a higher interest rate. Request information from your lender regarding lock procedures.

Foreclosure - A legal procedure in which real estate is sold by the lender to pay a defaulting borrower's debt .

Good Faith Estimate - An estimate of charges which a borrower is likely to incur in connection with a loan closing.

Housing Ratio - The ratio of the monthly housing payment to total gross monthly income. Also called Payment-to-Income Ratio or Front-End Ratio.

Interest Rate - The percentage of an amount of money which is paid for its use for a specified time.

Jumbo Loan - A loan for $300,700 or more in the continental United States (Alaska and Hawaii limits are higher). These limits are set by the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation. Because jumbo loans cannot be funded by these two agencies, they usually carry a higher interest rate.

Lender - The bank, mortgage company, or mortgage broker offering the loan. Many institutions only "originate" loans and then resell the obligation to third parties.

Life of Loan Cap - The maximum interest rate that can be charged during the life of the loan. Also called Lifetime Cap. This value is often expressed as an increment above the initial loan rate. For example, an adjustable rate loan with an initial rate of 7.25% and a 6% lifetime cap will never adjust above a rate of 13.25% (7.25+6.0).

Loan-To-Value Ratio - The relationship between the amount of the mortgage loan and the appraised value of the property expressed as a percentage. A LTV ratio of 90 means that a borrower is borrowing 90% of the value of the property and paying 10% as a down payment. For purchases, the value of the property is assumed to be the purchase price, for refinances the value is determined by an appraisal.

Lock - The period, expressed in days, during which a lender will guarantee a rate. Some lenders will lock rates at the time of application while others will allow the borrower to lock the rate after the application is taken. Request information from your lender regarding lock procedures.

Lock - The act of committing to a mortgage rate. This action, taken by a borrower some time between the application and the closing dates, is sometimes accompanied by a payment by the borrower to the lender. Opposite of float

Points - Prepaid interest paid by the borrower to the lender at closing. A point is equal to 1 percent of the loan amount (e.g. 1.5 points on a $100,000 mortgage would cost the borrower $1,500). Generally, by paying more points at closing, the borrower reduces the interest rate of his loan and thus future monthly payments.

Prepaids - Expenses such as taxes, insurance and assessments which are paid in advance of their due date and which must be paid by the buyer on a prorated basis at closing.

Prepayment - The ability to pay off the remaining balance of a loan.

Prepayment Penalty - Lenders who impose prepayment penalties will charge borrowers a fee if they wish to repay part or all of their loan in advance of the regular schedule.

Private Mortgage Insurance (PMI) - Paid by a borrower to protect the lender in case of default. PMI is typically charged to the borrower when the Loan-to-Value Ratio is greater than 80%.

Qualifying Ratio - The ratio of the borrower's fixed monthly expenses to his gross monthly income.

The Front-End Ratio is the percentage of a borrower's gross monthly income (before income taxes) that would cover the cost of PITI (Mortgage Principal Payment + Mortgage Interest Payment + Property Taxes + Homeowners Insurance).

The Back-End Ratio is the percentage of a borrower's gross monthly income that would cover the cost of PITI plus any other monthly debt payments like car or personal loans and credit card debt.

Please note that qualifying ratios are only a rough guideline in determining a potential borrower's credit-worthiness. Many factors such as excellent or poor credit history, amount of down payment, and size of loan will influence the decision to approve or disapprove a particular loan.
