Adjustable-rate Mortgage
A mortgage in which the interest rate is periodically readjusted to a base rate. For example a one-year ARM is reset once a year, on a prescribed date, to the level of the base rate plus a margin. For one-year ARMs, the base rate is often the one-year US Treasury bill yield, adjusted for a constant maturity.

Adjustment Period
Frequency that the interest rate of an adjustable-rate mortgage is reprised to a base rate. For one-year ARMs, the adjustment is made once a year; for three-year ARMs, every three years; etc.

Amortization
Gradual reduction of debt that occurs as periodic payments are applied to loan principal and interest at a rate that repays the loan principal by the end of the loan term.

Amortization Tables
Mathematical tables that show how a mortgage or other loan is gradually repaid by applying the appropriate amounts of the loan payment to principal and interest. In the beginning of the repayment period, only a small portion is applied to reducing the loan principal. As the loan approaches maturity, the portion of the payment applied to principal rises.

Annual Percentage Rate (APR)
The effective interest rate paid by a loan, expressed as an annual rate. APR measures the true interest cost of borrowing by including any fees or prepaid interest involved in obtaining a loan. For instance, if a borrower pays $500 in closing costs to obtain a $10,000 loan, the APR is higher than the simple interest rate because the borrower is repaying a $10,000 loan but only receiving net proceeds of $9,500. The federal Truth-in-Lending ACT requires to disclose the APR.

Appraisal Value
A mortgage lender determines the fair market value of a home by arranging an independent appraisal of the home's value. The appraisal uses local real estate market sales activity as a major basis for valuation. The appraisal value determines how much the lender is willing to loan. Generally, lenders make mortgage loans of up to 80% of the appraisal/fair market value of the home (see loan-to-value (LTV) ratio). For instance, a home appraised at $100,00 can be financed with a first-mortgage loan of $80,000. Before funding a larger percentage of the appraisal value, lenders generally require that borrowers obtain private mortgage insurance (PMI), which protects the lender from default.

Appreciation Rate
Percentage increase in the value of an asset, expressed at an annual rate. A home bought for $100,000 that appreciates five percent a year will be worth $127,600 after five years.

Base Rate
The underlying interest rate used as a benchmark, or index, for pricing variable-rate loans such as adjustable-rate mortgages, auto loans or credit cards.

Closing Costs
Charges associated with the underwriting and funding of a loan that are paid when the loan is about to be disbursed and the borrower about to take possession of the asset. Mortgage closing costs include title search, appraisal fee, legal and escrow service fees, and mortgage points.

Cost Analysis
A cost-benefit analysis that subtracts homeownership benefits from the homeownership costs. Including in the calculation of homeownership costs are: - Mortgage interest, including points - Closing costs - Property taxes and homeowners insurance - Private mortgage insurance (PMI) Included in benefits are: - Tax shield received from mortgage interest and points - Tax shield received from property taxes - Appreciation in value of the home due to market conditions (an increase in equity) - Loan principal repayment (an increase in equity)

Equity
Difference in the market value of a home and the total amount of debt or other encumbrances used to pay for a home. As market value increases and the borrower repays the mortgage loan, equity increases.

Homeowner's Insurance
Insurance coverage required by a mortgage lender to insure against such potentially catastrophic damage to a home (the lender's collateral) as flood, fire, tornado, or hurricane. Homeowner's insurance also provides liability coverage in case someone is injured on your property.

Impounds for Taxes and Insurance
Typically a month mortgage payment has four components: Principal, interest, taxes, and insurance ("PITI"). The taxes and insurance portions represent property taxes and homeowner's insurance premium, respectively. These are often required by the lender to be included in a monthly payment since regular and timely payment of both of these obligations improves the lender's collateral position.

Mortgage points
One mortgage point equals one percent of the loan amount (e.g., $1,000 on a mortgage loan of $100,000). Mortgage points are also called discount points. The IRS considers points to be a form of prepaid interest which means they can be deducted from taxable income. Lenders often require that the borrower pay one of two points at closing in exchange for a lower mortgage rate (the lender's target APR remains the same).

Negative Amortization
The opposite of amortization. In the case of an adjustable-rate mortgage with a payment cap, an upward adjustment in the interest rate may cause the loan payment to be insufficient to cover even the interest portion of the scheduled payment. In this case, the unpaid interest is added to the mortgage loan principal (if the loan agreement permits) and the loan amount increases.

Origination Fee
A loan fee, often as much as one percent of a loan amount, paid to the lender for processing and originating a loan.
• Back to Top

Payment Cap
A limit on the amount that the monthly payment can increase. A periodic cap limits the amount of the increase at each adjustment period. A lifetime cap limits the amount that the monthly payment can increase during the terms of the loan. A potential peril of payment caps is negative amortization. In the case of an adjustment-rate mortgage with a payment cap, raising the interest rates may cause the loan payment to be insufficient to cover even the interest portion of the scheduled payment. In this case, the unpaid interest may be added to the mortgage principal, if the loan agreement permits.

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 (LTV) ratio is greater than 80%. The Homeowners Act of 1998 mandates that a lender notify a borrower when the LTV falls below 80%, at which time a borrower is allowed to cancel the PMI coverage.

Property Taxes
Levies assessed on real property. A local assessor can provide information of tax rates.

Savings Rate
The interest rate expected on the most conservative of investments. A conservative estimate should be used if the money is intended to be invested for a short time only or the investor is unwilling to risk losing any of the investment. A money market rate of between 5.5. and 6.5 percent is a conservative rate (as of June 2000).

Tax Rates
The five federal income tax rates range from 15% to 39.6%. To determine the applicable income tax rate, see the IRS' tax rate schedules (if adjusted gross income is $100,000 or more) and tax tables (for AGI under $100,000). Several states, including Washington, Alaska, and Wyoming, do not levy income taxes.

Tax Savings
The amount saved on taxes by itemizing deductions on income tax returns (FinanCenter.com calculators assume deductions are itemized if they exceed standard deductions). Mortgage interest and property taxes are tax deductible, and therefore generate a tax shield benefit.
• Back to Top

Tax Shield
The amount saved in taxes by taking deductions. To measure the tax shield benefit, multiply the amount of the deduction by your tax rate. For instance, if an investor deducts $1,000 in mortgage interest expense and is in the 28% income tax bracket, she enjoys a tax shield benefit of $280.

Term
Period of loan, expressed in years. Residential mortgage loans typically are made for 15 or 30 years terms.
