The mortgage world loves its acronyms. Here's what they actually mean.
APR (Annual Percentage Rate)
The total yearly cost of your loan expressed as a percentage. It includes the interest rate plus fees, so it's usually slightly higher than your rate. Use APR to compare loan offers apples-to-apples.
Amortization
How your loan payments are split between principal (the amount you borrowed) and interest over time. Early payments are mostly interest; later payments are mostly principal.
Closing Costs
Fees paid at the end of the transaction — typically 2–5% of the purchase price. Includes appraisal, title insurance, origination fees, prepaid taxes, and insurance.
Conventional Loan
A mortgage not backed by a government agency. Usually requires a credit score of 620+ and a down payment of at least 3%. PMI is required if you put less than 20% down.
DTI (Debt-to-Income Ratio)
Your total monthly debt payments divided by your gross monthly income. Most lenders want this below 43%, though some loan programs allow higher.
Escrow
An account held by your lender to pay your property taxes and homeowners insurance. A portion of each mortgage payment goes into escrow so these bills are covered automatically.
FHA Loan
A government-backed loan through the Federal Housing Administration. Popular with first-time buyers because it allows credit scores as low as 580 and down payments as low as 3.5%.
Fixed-Rate Mortgage
A loan where the interest rate stays the same for the entire term (usually 15 or 30 years). Your principal and interest payment never changes.
Adjustable-Rate Mortgage (ARM)
A loan where the rate is fixed for an initial period (e.g., 5 or 7 years) then adjusts periodically based on market conditions. Can start lower than fixed rates.
LTV (Loan-to-Value Ratio)
The loan amount divided by the home's appraised value. An LTV of 80% means you're borrowing 80% and putting 20% down.
PMI (Private Mortgage Insurance)
Insurance you pay when your down payment is less than 20% on a conventional loan. It protects the lender, not you. It drops off once you reach 20% equity.
Points (Discount Points)
Prepaid interest you can buy to lower your rate. One point = 1% of the loan amount. Useful if you plan to stay in the home long-term.
Pre-Approval
A lender's written commitment that you qualify for a specific loan amount based on verified income, assets, and credit. Much stronger than pre-qualification.
Pre-Qualification
An informal estimate of what you might qualify for based on self-reported information. No verification — it's a starting point, not a commitment.
Title Insurance
Protects you and the lender against claims on the property's ownership history. A one-time fee paid at closing.
Underwriting
The process where your lender reviews all your documentation to make a final decision on your loan. This is the last step before clear-to-close.
USDA Loan
A zero-down-payment loan for homes in eligible rural and suburban areas. Income limits apply, but many areas around Washington's cities qualify.
VA Loan
A zero-down, no-PMI loan for eligible veterans, active-duty service members, and surviving spouses. One of the best mortgage products available.
