Adjustable-rate mortgage

ARM

A loan whose rate can change after an initial fixed period, so your payment can rise or fall over time.

Amortization

The schedule by which your loan is paid off; early on most of each payment is interest, later most goes to principal.

Amortization schedule

Annual percentage rate

APR

The yearly cost of the loan including the rate plus most fees, so it usually runs a bit higher than the rate; handy for comparing lenders.

Appraisal

A licensed appraiser's independent opinion of the home's value — not its price — which the lender uses to make sure the loan isn't larger than the property supports.

Appreciation

The increase in a home's value over time; the rate you assume drives any rent-vs-buy comparison.

Rent vs. buy

Biweekly payments

Paying half your monthly payment every two weeks — 26 halves a year, which equals one extra full payment annually.

Extra-payment payoff

Break-even

The point where an upfront cost (points, refinance fees) has been recovered by the monthly savings it bought.

Refi break-even

Certificate of eligibility

COE

The VA document proving your entitlement — how much you have, what's charged to a kept loan, and whether you're funding-fee exempt; lenders usually pull it electronically in minutes.

Closing costs

One-time fees to finalize the loan and purchase — lender fees, title, taxes, prepaids — usually a few percent of the price.

Cash-to-close calculator

Closing Disclosure

CD

The final statement of your exact loan terms and costs; you must receive it at least three business days before closing.

Conforming loan

A conventional loan that fits Fannie Mae / Freddie Mac size limits, so it qualifies for standard pricing.

Conventional loan

A loan not backed by a government program (FHA/VA/USDA); usually needs decent credit and 3%+ down.

Debt-to-income ratio

DTI

Your monthly debt payments divided by gross monthly income; lenders use it to judge what you can afford.

DTI calculator

Discount points

Optional upfront fees to buy down your rate; one point is 1% of the loan.

Points break-even

Down payment

The cash you put toward the purchase up front; the rest is the loan.

Earnest money

A good-faith deposit when your offer is accepted; applied to your costs at closing.

Equity

The part of the home you own — its value minus what you still owe.

Escrow

An account the lender uses to collect and pay your taxes and insurance with your payment; also the neutral party holding funds during closing.

FHA loan

A government-backed loan with lower down-payment and credit requirements, in exchange for mortgage insurance.

Fixed-rate mortgage

A loan whose rate — and principal-and-interest payment — stays the same for the whole term.

Gift funds

Money from family or an allowed source toward your down payment; needs a gift letter and proof of transfer.

Homeowners insurance

Coverage protecting the home; lenders require it and usually collect it through escrow.

Jumbo loan

A loan larger than the conforming limit; stricter requirements because it can't be sold to Fannie/Freddie.

Lender credit

Money from the lender toward your closing costs in exchange for a higher rate — discount points in reverse.

Points break-even

Loan Estimate

LE

A standardized form showing your loan's rate, payment, and costs; you get it within three business days of applying, built for comparing lenders.

Loan Estimate comparator

Loan term

How long the loan is scheduled to last — shorter terms mean higher payments but far less total interest.

Loan-to-value ratio

LTV

The loan amount divided by the home's value; lower LTV (more equity) usually means better terms and no PMI.

Mortgage insurance premium

MIP

FHA's mortgage insurance; depending on your down payment it can last the life of the loan.

PMI/MIP removal tracker

NMLS

NMLS

The national registry of mortgage companies and loan officers; every legitimate one has an NMLS ID you can verify for free.

NMLS lookup helper

Opportunity cost

What money could have earned elsewhere — the return a renter's would-be down payment makes if invested instead.

Rent vs. buy

Origination fee

What the lender charges to process and underwrite your loan; negotiable.

PITI

The four parts of a typical payment: principal, interest, taxes, insurance.

Full PITI calculator

Pre-approval

A lender's written, conditional statement that you qualify for a loan amount based on verified income, assets, and credit — not a commitment to lend; final approval depends on the property and underwriting.

Readiness quiz

Pre-qualification

A rough estimate of what you might borrow based on info you provide, without verification.

Prepaids

Upfront amounts for taxes, insurance, and interest you pre-fund at closing; costs, not fees.

Prepayment

Paying extra toward principal ahead of schedule, which shortens the loan and cuts total interest.

Extra-payment payoff

Prepayment penalty

A fee some loans charge for paying off early — rare on recent consumer mortgages, but worth confirming before you prepay.

Principal

The amount you borrowed and still owe, separate from interest.

Principal & interest

P&I

The core loan payment — repaying what you borrowed plus the cost of borrowing it; taxes and insurance ride on top.

Payment calculator

Private mortgage insurance

PMI

Insurance on a conventional loan when you put less than 20% down; cancellable as you build equity.

PMI removal tracker

Rate lock

A lender's guarantee to hold your rate for a set window while you close.

Recast

Paying a lump sum toward principal and having the lender re-amortize, lowering your payment at the same rate.

Recast calculator

Refinance

Replacing your current mortgage with a new one, usually to lower the rate or change the term.

Refi break-even

Reserves

Savings the lender wants to see you'll have left after closing, often measured in months of payments.

Residual income

The income left over each month after housing costs and debts; VA sets regional minimums by family size, and it's the test that can approve a file a plain DTI number would flag.

VA entitlement calculator

Seller concessions

Closing costs the seller agrees to cover for you, within limits set by the loan type.

Servicer

The company that collects your payments and manages escrow after closing — often not the lender you applied with.

Title insurance

A policy protecting you and the lender against title problems; you can shop for it.

Your rights hub

Transfer tax

A one-time state or local tax when a property's title changes hands, usually a percentage of the sale price.

Transfer tax estimator

Trigger lead

Your mortgage credit inquiry sold to other lenders so they can solicit you — now banned by federal law in most cases.

Trigger-lead toolkit

Underwriting

The lender's process of verifying your finances and the property to decide approval.

USDA loan

A government-backed loan for eligible rural/suburban buyers, often no down payment.

VA entitlement

The amount VA guarantees for your loans; what's not tied up in a kept VA loan determines your next $0-down ceiling.

VA entitlement calculator

VA funding fee

A one-time VA charge — typically 1.25% to 3.3% of the loan on a purchase — that keeps the program running; usually financed into the loan, higher on repeat use, and waived for veterans receiving VA disability compensation, surviving spouses receiving Dependency and Indemnity Compensation, and active-duty Purple Heart recipients.

The VA funding fee, explained

VA loan

A government-backed loan for eligible veterans and service members, often no down payment and no monthly mortgage insurance.

VA entitlement calculator
