A

Adjustable-Rate Mortgage (ARM)

A mortgage with an interest rate that changes periodically based on a financial index, after an initial fixed period. ARMs are named by their fixed period and adjustment frequency: a 5/1 ARM is fixed for 5 years then adjusts annually.

Amortization

The process of gradually paying off a loan through regular payments that cover both principal and interest. Early payments are mostly interest; later payments shift toward principal.

Annual Percentage Rate (APR)

The total yearly cost of a mortgage expressed as a percentage, including the interest rate, points, mortgage insurance, and some fees. APR is always equal to or higher than the interest rate.

Appraisal

An independent estimate of a property's market value, conducted by a licensed appraiser. Required by lenders to ensure the property is worth at least the loan amount.

Assumable Mortgage

A mortgage that can be transferred from the seller to the buyer. VA and FHA loans are assumable; most conventional loans are not. When rates are rising, assuming a low-rate mortgage can be extremely valuable.

B

Balloon Mortgage

A loan with fixed payments for a set period (5–10 years), after which the entire remaining balance is due in a single 'balloon' payment. Risky unless you plan to sell or refinance before the balloon date.

Basis Point

One-hundredth of one percent (0.01%). Mortgage rates and bond yields are commonly quoted in basis points. A 25-basis-point rate increase equals 0.25%.

Bridge Loan

A short-term loan used to finance the purchase of a new home while waiting for the sale of an existing home. Higher rates and fees; typically 6–12 month terms.

C

Cash-Out Refinance

Refinancing for more than the current mortgage balance and taking the difference as cash. The maximum cash-out is typically limited to 80% LTV (keeping 20% equity).

Certificate of Eligibility (COE)

A document from the VA that proves a veteran's or service member's eligibility for VA loan benefits. Can be obtained online through the VA portal in minutes.

Clear to Close (CTC)

Lender notification that all underwriting conditions have been met and the loan is approved to proceed to closing. Typically issued 1–3 days before closing.

Closing Disclosure

A five-page document provided to borrowers at least 3 business days before closing that shows final loan terms, monthly payment, and all closing costs.

Conforming Loan

A mortgage that meets Fannie Mae/Freddie Mac guidelines, including loan limits ($766,550 in most areas for 2024). Conforming loans are eligible for secondary market sale.

Construction Loan

A short-term loan that finances the building of a home. Interest is paid on draws during construction; the loan converts to a permanent mortgage upon completion.

Conventional Loan

Any mortgage not backed by a government agency. Can be conforming (meets GSE guidelines) or non-conforming/jumbo (exceeds conforming limits).

Credit Score

A numerical representation of credit risk, typically ranging from 300–850. FICO Score 2, 4, and 5 are the specific models used in mortgage underwriting.

D

Debt-to-Income Ratio (DTI)

Monthly debt payments divided by gross monthly income. Lenders evaluate front-end DTI (housing costs only) and back-end DTI (all debts). Most loans cap back-end DTI at 43–50%.

Deed of Trust

In many states, a three-party mortgage document between borrower, lender, and trustee. The trustee holds legal title until the loan is paid off.

Good-faith deposit made by the buyer when an offer is accepted, typically 1–3% of purchase price. Applied to down payment at closing; may be forfeited if buyer backs out without contingency protection.

Equity

Escrow Account

An account managed by the lender (or a third party) that holds monthly property tax and insurance contributions. Lender pays tax and insurance bills from this account.

A mortgage insured by the Federal Housing Administration. Allows lower credit scores (580+) and down payments (3.5%). Requires mortgage insurance premiums (MIP) for the life of most loans.

Fixed-Rate Mortgage

A mortgage with an interest rate that never changes for the life of the loan. Monthly principal and interest payments remain constant.

Flood Insurance

Required by lenders for homes in FEMA-designated Special Flood Hazard Areas (SFHA). Not covered by standard homeowner's insurance.

Pre-2015 disclosure of estimated mortgage costs. Replaced by the Loan Estimate under TRID (TILA-RESPA Integrated Disclosure) rules.

The fixed percentage added to the ARM index to determine the fully-indexed rate. Typical margins: 2.25%–3.5%. Set at origination and doesn't change.

Mortgage Note

The legal document a borrower signs promising to repay the loan. Contains the interest rate, payment schedule, and terms.

N
