What's the difference between pre-qualification and pre-approval?

Pre-qualification is a quick, unverified estimate. Pre-approval means a lender has checked your actual income, assets, and credit and issued a conditional commitment letter — it's what sellers take seriously.

Do I need to know all these terms before I start house hunting?

No. Bookmark this page and look things up as they come up — that's exactly what it's here for. You'll pick up most of it naturally as you go through the roadmap.

What's the single most important term for a first-time buyer to understand?

Closing costs. It's the number first-timers most often forget to budget for, on top of the down payment — usually 2-5% of the purchase price, due in cash at closing.

40 terms, zero jargon

The glossary

Real estate has its own language, and nobody hands you the dictionary. Here it is — 40 terms, defined the way a friend would explain them.

A

Adjustable-Rate Mortgage (ARM): A mortgage with an interest rate that's fixed for an initial period (often 5, 7, or 10 years), then adjusts periodically based on a market index. Payments can go up or down after the fixed period ends. Read more →
Amortization: The schedule by which your loan is paid off over time through regular payments. Early payments are mostly interest; later payments are mostly principal, even though the total payment stays the same.
Annual Percentage Rate (APR): The true yearly cost of your loan, including the interest rate plus most lender fees. It's usually a bit higher than the plain interest rate — use it to compare offers apples-to-apples.
Appraisal: An independent, licensed professional's estimate of a home's market value, ordered by your lender to confirm the home is worth what you're borrowing against it.
Appraisal Gap: The difference when a home appraises for less than your agreed purchase price. You typically have to cover the gap in cash, renegotiate the price, or (if your contract allows) walk away.

C

Closing: The final step of a home purchase, where ownership legally transfers. You sign the loan and title paperwork, pay remaining closing costs, and receive the keys.
Closing Costs: Fees due at closing beyond the down payment — typically 2-5% of the purchase price, covering things like lender fees, title insurance, appraisal, and prepaid taxes/insurance. Read more →
Closing Disclosure: A standardized form your lender must give you at least three business days before closing, spelling out your final loan terms and closing costs. Compare it against your earlier Loan Estimate.
Contingency: A condition in your purchase contract that must be met or you can back out without losing your earnest money — common ones cover financing, inspection, and appraisal.
Conventional Loan: A mortgage not insured or guaranteed by a government agency (unlike FHA or VA loans). Usually requires a stronger credit profile but can have lower fees for well-qualified buyers.

D

Debt-to-Income Ratio (DTI): The percentage of your gross monthly income that goes toward debt payments, including your future mortgage. Lenders use it — alongside the 28/36 rule — to gauge how much you can safely borrow. Read more →
Down Payment: The cash you pay upfront toward the home's price, with the rest financed by your mortgage. It ranges from 3% to 20%+ depending on loan type — it's separate from closing costs.

E

Earnest Money: A good-faith deposit — usually 1-3% of the purchase price — that shows a seller you're serious. It's held in escrow and credited toward your down payment at closing, unless you back out uncovered by a contingency. Read more →
Equity: The portion of your home you actually own outright — the market value minus whatever you still owe on the mortgage. It grows as you pay down principal and as the home appreciates.
Escrow: A neutral third party (usually a title company) that holds funds and documents during a transaction. Also refers to the ongoing account your lender uses to collect and pay your property taxes and insurance.

F

FHA Loan: A mortgage insured by the Federal Housing Administration, popular with first-time buyers for its lower down payment (as low as 3.5%) and more flexible credit requirements — it does require mortgage insurance.
Fixed-Rate Mortgage: A mortgage where the interest rate never changes for the life of the loan (commonly 15 or 30 years), so your principal-and-interest payment stays the same every month. Read more →

H

Home Inspection: A professional's top-to-bottom check of a home's condition — roof, foundation, electrical, plumbing, HVAC — done before you finalize the purchase, so you know what you're actually buying. Read more →
Homeowners Association (HOA): An organization that manages shared rules and amenities in some communities and condo buildings, funded by mandatory monthly or annual dues. Read the rules and financials before you buy in.
Homeowners Insurance: A policy that protects your home and belongings against damage, theft, and liability. Lenders require it, and the annual cost is usually rolled into your monthly payment via escrow.

I

Interest Rate: The percentage cost of borrowing money, charged annually on your outstanding loan balance. It's the single biggest lever on what your monthly payment ends up being.

L

Loan Estimate: A standardized form lenders must send within three days of your application, outlining estimated rate, monthly payment, and closing costs — useful for comparing lenders side by side.
Loan-to-Value Ratio (LTV): Your loan amount divided by the home's appraised value, expressed as a percentage. A smaller down payment means a higher LTV, which usually means a higher rate and, below 80%, mortgage insurance.

M

Mortgage: A loan used to buy real estate, secured by the property itself — if you stop paying, the lender can foreclose. "Mortgage" and "home loan" are used interchangeably.
Mortgage Broker: A licensed professional who shops your loan application across multiple lenders to find competitive terms, rather than lending their own money like a bank does.
Multiple Listing Service (MLS): The database real estate agents use to list and search homes for sale in a given area. Most public home-search sites pull their listings from an MLS feed.

O

Origination Fee: A fee a lender charges for processing your loan application, typically 0.5-1% of the loan amount. It's one of several line items that make up your total closing costs. Read more →

P

Pre-Approval: A lender's conditional commitment to loan you a specific amount, based on verified documentation of your income, assets, and credit. Far stronger than pre-qualification when making an offer. Read more →
Pre-Qualification: A quick, informal estimate of what you might be able to borrow, based on unverified numbers you self-report. Useful for early planning, not for making a competitive offer. Read more →
Principal: The original amount you borrowed (or the remaining balance owed), separate from interest. Your monthly payment is split between principal and interest, shifting toward principal over time.
Private Mortgage Insurance (PMI): Insurance that protects the lender (not you) when your down payment is below 20% on a conventional loan. It's an added monthly cost you can usually drop once you reach 20% equity.
Property Tax: An annual tax charged by your local government based on your home's assessed value, usually collected monthly via your mortgage escrow account and paid out on your behalf.

R

Rate Lock: A lender's guarantee to hold your quoted interest rate for a set period (often 30-60 days) while your loan is processed, protecting you from rate swings before closing.
Real Estate Agent: A licensed professional who represents buyers or sellers in a transaction. A buyer's agent works on your behalf to find homes, negotiate, and guide you through closing.

S

Sales Contract (Purchase Agreement): The legally binding document that spells out the agreed price, contingencies, closing date, and terms of the sale once a seller accepts your offer.
Seller Concessions: Costs the seller agrees to cover on your behalf, often toward closing costs or repairs, typically negotiated as part of the offer or after inspection.

T

Title: The legal right of ownership to a property. A "clean title" means no competing claims, liens, or disputes — confirmed through a title search before closing.
Title Insurance: A one-time-fee policy that protects you (and your lender) against past ownership problems that a title search might have missed — undisclosed liens, forged signatures, and the like.

U

Underwriting: The lender's detailed review of your finances and the property's value to make a final lending decision, happening after your offer is accepted and before you're cleared to close. Read more →

V

VA Loan: A mortgage guaranteed by the Department of Veterans Affairs for eligible service members, veterans, and some spouses — often available with no down payment and no PMI.
