Acre: A U.S. measure of land or sea equaling 4,840 square yards, or 43,560 square feet. It's roughly the size of one football field, without the end zones. (Note: Acre comes from the Anglo-Saxon aecer, meaning land, or anything sown. It was based on the amount of land that could be plowed by one man behind an ox in one day.)

Adjustable Rate Mortgage (ARM): A mortgage loan with payments usually lower than a fixed rate initially, but is subject to changes in interest rates. There are a variety of ARMs that can have an initial interest rate that lasts three to 10 years, adjusting annually thereafter. They are described as 3/1, 5/1, 7/1 and 10/1. A 3/1 ARM starts out with a low rate that lasts three years, then is adjusted annually. A 5/1 ARM has an introductory rate that lasts five years, and 7/1 and 10/1 ARMs have intro rates that last seven and 10 years. The monthly payment amount is usually subject to a cap.

Amortization: Repayment of a mortgage loan through regular monthly installments of principal and interest. At the end of the scheduled payments (e.g., monthly payments for 15 or 30 years), you will own your home.

Annual Percentage Rate (APR): Calculated by using a standard formula, the APR is expressed as a yearly rate (e.g., 8.107% APR) and includes the interest, points (discount and origination), mortgage insurance, and other fees. The APR on a mortgage will usually be higher than the stated interest rate because the APR includes fees and the interest rate doesn't.

Appraisal: Prepared by a qualified professional (an appraiser), it is an estimation of a property's fair market value. A lender usually requires an appraisal before loan approval to ensure that the mortgage loan amount is not more than the value of the property.

Appraiser: A qualified professional who uses his or her experience and knowledge to prepare the appraisal. An appraiser must have a state license before his or her appraisals may be used as the basis for a federally-backed mortgage.

Assessment: Value placed on real estate by governmental assessors as a basis for collecting property taxes.

Assumable mortgage: A mortgage that can be transferred from a seller to a buyer. The buyer then takes over payment of an existing loan.

Automated Underwriting System: A computerized system used to assess information provided by a borrower, plus public information about the borrower, to quickly determine whether a loan should be pre-approved.

Automated valuation models (AVM): Computer programs that use data to provide real estate market analysis and estimates of value. Real estate professionals use AVMs to support their work in determining an estimated market value of a property.

B

Certificate of title: A document provided by a qualified source (such as a title company) that shows the property legally belongs to the current owner. Before the title is transferred at closing, it must be free and clear of all liens or other claims. Title searches also sometimes clarify issues such as easements. (Also see: Title)

Closing: Also known as settlement, this is the final phase of a real estate transaction when the property is formally transferred from the seller to the buyer. It is usually handled by a title company, though some states require an attorney at closing. Closing is when the buyer takes on any loan obligations and receives title from the seller.

Closing costs: Customary costs above and beyond the sale price of the property that must be paid to cover the transfer of ownership at closing. These fees could include: Loan Fees, Cost of Abstract, Recording Deed and Mortgage, Documentary Stamps on Deed, Escrow Fees, Real Estate Commissions, Attorney's Fees, Title Insurance, Survey Charge, Appraisal Fees, and Inspection Fees.

Covenant: Also referred to as a restrictive covenant, it is an agreement, promise or obligation made in a deed that is inseparable from the property. The restrictions must be enforced by subsequent buyers of the property. Examples include: Maintaining a property in a reasonable state of repair; preserving a sight-line for a neighboring property; and not building on parts of the property.

Easement: A right-of-way giving individuals other than the owner permission to use a property for a specific purpose.

Encumbrance: A legal right or interest that affects or limits complete ownership and control over a property. It can take numerous forms, such as zoning ordinances, easement rights, claims, mortgages, liens, charges, pending legal action, unpaid taxes or restrictive covenants. An encumbrance does not necessarily prevent transfer of the property to another, but may diminish its value. A title search will usually reveal the existence of encumbrances, and it is up to the buyer to determine whether he or she wants to purchase the property with the encumbrance.

Equity: Calculated by subtracting the amount still owed on the mortgage loan and any liens from the fair market value of the property. Equity grows as the mortgage is paid down and the property appreciates in value.

Escrow account: A neutral third-party account holding documents and money during a real-estate transfer until the sale is finalized. It can also be an account in which money for property taxes, homeowners insurance, and mortgage insurance is paid.

The Fed: The Federal Reserve System, a network of twelve Federal Reserve Banks and affiliated branches that serves as the central bank of the United States. "The Fed" also often refers to the Board of Governors of the Federal Reserve System. The Fed Board sets overnight lending rates for banks. This is what banks charge each other for borrowing money overnight, which they do when they need to replenish their reserves. The Fed uses these rates to control inflation: if it lowers these rates, more money flows in the form of loans to consumers and businesses; if it raises rates, there are fewer loans. Mortgage rates are not tied to the Fed's rates, but they are influenced by it.

Federal Housing Administration (FHA): The FHA was established in 1934 to advance homeownership opportunities for all Americans. It provides mortgage insurance on loans made by FHA-approved lenders throughout the United States and its territories.

FICO: An acronym for the Fair Isaac Corporation, the company that developed the most commonly used credit scoring system. Credit reporting agencies issue FICO scores to lenders who in turn use them to calculate the risk on a loan.

Fixed-rate mortgage: A mortgage with payments that remain the same throughout the life of the loan because the interest rate and other terms do not change.

Flood insurance: Covers a homeowner for property damage from natural flooding. If a home is located in an area prone to flooding, the lender will require flood insurance before approving a loan.

Foreclosure: The legal process by which a bank or lender sells or repossesses a mortgaged property because the borrower could not pay the loan.

Freddie Mac: Created in 1970 by the federal government as the Federal Home Loan Mortgage Corporation, it is a stockholder-owned corporation chartered by Congress to increase the supply of funds that mortgage lenders, such as commercial banks, mortgage bankers, savings institutions and credit unions, can make available to homebuyers and multifamily investors.

G

Ginnie Mae: A government-owned corporation overseen by the U.S. Department of Housing and Urban Development, Ginnie Mae pools FHA-insured and VA-guaranteed loans to back securities for private investment. Like Fannie Mae and Freddie Mac, the investment income provides funding that may then be lent to eligible borrowers by lenders. Ginnie Mae stands for Government National Mortgage Association (GNMA).

Good faith estimate (GFE): A written estimate of all expected closing fees including pre-paid and escrow items as well as lender charges. It must be given to the borrower, by a potential lender, within three days after submission of a mortgage loan application.

Margin: Expressed in percentage points, the amount a lender adds to an index to determine the interest rate on an adjustable rate mortgage.

Median price: The median price is one way to specify the midpoint of transaction prices in a period of time. Half of all transactions are above the median price and half are below. (Note: This differs from a mean average where the sum of the values is divided by the number of values (e.g. 2 + 3 + 7 = 12, then 12 ÷ 3 = 4. Four is the mean average of that set of numbers. Three is the median).

Mortgage: A lien against real estate given by a buyer or property owner to the lender as security for money borrowed.

Single family home: A residential structure designed as one dwelling; includes town homes that have shared walls, but independent access to the outside. (Note: Search results may include "miscellaneous" homes that may be single family, but are not classified as such.)

Square footage: Generally, only finished, heated space counts, such as the main finished floors, a finished basement, and/or a finished attic. A finished garage that is attached to and part of the residence may be included in this calculation as well. Square footage is computed by multiplying the length and width dimensions of a finished area.

Stick-built home: This is a home built piece-by-piece at the site.

Stories of a home: This is determined by adding up the horizontal levels of a building, which includes floors 1-4 and excludes finished and unfinished basements and finished and unfinished attics.

Tax assessed value: This figure varies throughout the U.S. since it is determined by the taxing authority of the city, county, or state where you live. Sometimes it is the same as the market assessed value and other times counties will multiply the market value by an assessment ratio to get the tax assessed value, which is often lower than the market assessed value. For example, suppose where you live, homes are assessed at 100% of market value. If you have a home that has a market value of \$150,000, your home will be assessed at \$150,000. However, if your taxing authority assesses homes at 70% of value, your \$150,000 market value home will have a tax assessed value of \$105,000.

Tear-down: A property where the value of the lot as a potential site for a new home exceeds the value of the existing home on the lot.

Where an existing home that is considered more valuable demolished and a new one — possibly larger — is built in its place.

Three-quarters bath: A room with a toilet, sink and shower. It does not include a bathtub.

Total rooms: As defined by the local assessor's office, it is the number of rooms in the residence such as bedroom, bathroom, dining room, family room, kitchen, living room, attic, basement, and garage.

For homes with open floor plans, areas that have distinct and separate uses can be counted as a room. For example, a kitchen that flows into another larger room that has a dining room table may be considered two rooms; a "breakfast bar" or breakfast nook would not. Ancillary rooms such as basements, garages and sun rooms that are finished and enclosed can be counted as a room.

Truth-in-Lending: A federal law obligating a lender to give full written disclosure of all fees, terms, and conditions associated with the loan's initial period and any adjustments to the remaining term of the loan.

U

Underwriting: The process of analyzing a loan application to determine the amount of risk involved in making the loan. It includes a review of the potential borrower's credit history and a judgment of the property value.

V

Value range: The value range on Zillow indicates the certainty of the Zestimate valuation. The wider the range, the less data used in developing a Zestimate; the narrower the range, the more accurate the Zestimate.
