Adjustable-rate mortgage (ARM)
A mortgage in which the interest changes periodically, according to corresponding fluctuations in an index. All ARMs are tied to indexes.

Adjustment date
The date the interest rate changes on an adjustable-rate mortgage (ARM).

Amortization
The loan payment consists of a portion which will be applied to pay the accruing interest on a loan, with the remainder being applied to the principal. Over time, the interest portion decreases as the loan balance decreases, and the amount applied to principal increases so that the loan is paid off (amortized) in the specified time.

Amortization schedule
A table which shows how much of each payment will be applied toward principal and how much toward interest over the life of the loan. It also shows the gradual decrease of the loan balance until it reaches zero.

Annual percentage rate (APR)
This is not the note rate on your loan. It is a value created according to a government formula intended to reflect the true annual cost of borrowing, expressed as a percentage. It works sort of like this, but not exactly, so only use this as a guideline: deduct the closing costs from your loan amount, then using your actual loan payment, calculate what the interest rate would be on this amount instead of your actual loan amount. You will come up with a number close to the APR. Because you are using the same payment on a smaller amount, the APR is always higher than the actual not rate on your loan.

Application
The form used to apply for a mortgage loan, containing information about a borrower’s income, savings, assets, debts, and more.

Appraisal
A written justification of the price paid for a property, primarily based on an analysis of comparable sales of similar homes nearby.

Appraised value
An opinion of a property's fair market value, based on an appraiser's knowledge, experience, and analysis of the property. Since an appraisal is based primarily on comparable sales, and the most recent sale is the one on the property in question, the appraisal usually comes out at the purchase price.

Appraiser
An individual qualified by education, training, and experience to estimate the value of real property and personal property. Although some appraisers work directly for mortgage lenders, most are independent.

Appreciation
The increase in the value of a property due to changes in market conditions, inflation, or other causes.

Assessed value
The valuation placed on property by a public tax assessor for purposes of taxation.

Assessment

Assessor
A public official who establishes the value of a property for taxation purposes.

Asset
Items of value owned by an individual. Assets that can be quickly converted into cash are considered "liquid assets." These include bank accounts, stocks, bonds, mutual funds, and so on. Other assets include real estate, personal property, and debts owed to an individual by others.

Assignment
When ownership of your mortgage is transferred from one company or individual to another, it is called an assignment.

Assumable mortgage
A mortgage that can be assumed by the buyer when a home is sold. Usually, the borrower must "qualify" in order to assume the loan.

Assumption
The term applied when a buyer assumes the seller’s mortgage.
