- Amortization
- The schedule by which your loan balance is paid down over time through regular principal-and-interest payments.
- Annual Percentage Rate (APR)
- A broader measure of borrowing cost that folds certain fees into the rate, so you can compare loan offers on more than the note rate alone.
- Appraisal
- A licensed appraiser's independent estimate of a home's market value, used by the lender to confirm the property supports the loan.
C
- Cash-Out Refinance
- A refinance that replaces your mortgage with a larger one and returns the difference to you in cash from your home equity. See our cash-out refinance guide.
- Closing Costs
- The fees paid to finalize a mortgage -- lender fees, title, appraisal, taxes, and prepaids -- typically due at closing.
- Conforming Loan
- A loan that meets Fannie Mae / Freddie Mac size and guideline limits. See the 2026 conforming limit.
- Conventional Loan
- A mortgage not insured by a government agency (VA/FHA), following Fannie Mae or Freddie Mac guidelines.
D
- Debt-to-Income Ratio (DTI)
- The share of your gross monthly income that goes to debt payments; a key qualification factor.

E
- Earnest Money
- A good-faith deposit a buyer puts down with an offer, applied toward the purchase at closing.
- Equity
- The portion of your home you own outright -- its value minus what you still owe.
- Escrow
- An account the lender uses to collect and pay property taxes and insurance on your behalf, spread across your monthly payment.
F
- FHA Loan
- A mortgage insured by the Federal Housing Administration, popular with first-time and credit-building buyers for its lower down payment.

L
- Loan Estimate
- A standardized form lenders provide within three business days of application, laying out rate, payments, and closing costs so you can compare.
- Loan-to-Value Ratio (LTV)
- The loan amount as a percentage of the home's value; lower LTV generally means less risk and better terms.

O
- Origination
- The process of creating a new mortgage, from application through underwriting to closing.
P
- Points
- Optional up-front fees paid to lower your interest rate (discount points), each typically costing one percent of the loan amount.
- Pre-Approval

- Private Mortgage Insurance (PMI)
- Mortgage insurance on a conventional loan, usually required under 20 percent equity and removable once you reach it.
