PRINCIPAL
The principal is the original amount of money borrowed in a mortgage — the base amount you owe before interest. As you make monthly payments, a portion reduces the principal and a portion pays interest. Early in a mortgage, most of your payment goes to interest; over time, more goes to principal.
If you buy a $400,000 home with a 20% down payment, your principal loan amount is $320,000. Your monthly payments gradually reduce this balance over 15 or 30 years.
INTEREST
Interest is the cost of borrowing money, expressed as a percentage of the loan balance. On a mortgage, interest accrues daily based on your outstanding principal. The rate you receive depends on your credit score, down payment, loan type, and prevailing market rates.
On a $300,000 mortgage at 7% interest, you pay approximately $20,906 in interest in the first year alone. Over 30 years, total interest paid would be roughly $418,000 — more than the original loan.
AMORTIZATION
Amortization is the process of paying off a debt through scheduled regular payments over time. With a fully amortizing mortgage, each payment reduces the loan balance so that the debt is completely paid off at the end of the term. An amortization schedule shows exactly how much goes to principal vs. interest each month.
On a 30-year, $300,000 mortgage at 7%, your first payment of $1,996 splits: $246 to principal and $1,750 to interest. By month 360, nearly the entire payment goes to principal.
ESCROW
Escrow is a financial arrangement where a neutral third party holds funds on behalf of two parties. In real estate, escrow accounts hold property tax and homeowner's insurance payments so they can be paid automatically. Most lenders require escrow accounts to protect their collateral investment.
If your annual property taxes are $6,000 and insurance $1,200, your lender collects an extra $600/month in escrow. When taxes and insurance are due, the lender pays them directly from your escrow account.
EQUITY
Home equity is the portion of your property you truly own — the difference between your home's current market value and the amount you still owe on your mortgage. Equity grows as you pay down your loan and as your home appreciates in value. It can be accessed through a home equity loan or HELOC.
If your home is worth $500,000 and you owe $300,000, your equity is $200,000 (40%). If the home rises to $600,000, your equity grows to $300,000 even without making extra payments.
REFINANCE
Refinancing is replacing your existing mortgage with a new loan — typically to secure a lower interest rate, reduce monthly payments, change loan terms, or access home equity. While refinancing can save significant money, it involves closing costs (typically 2–5% of the loan) and resets your amortization schedule.
Millions of Americans refinanced during 2020–2021 when 30-year rates fell near 2.65%. A homeowner with a 5% rate who refinanced to 2.75% on a $300,000 loan saved roughly $400/month.
APPRAISAL
A home appraisal is an independent professional assessment of a property's fair market value. Lenders require appraisals before approving a mortgage to ensure the home is worth at least as much as the loan amount. Appraisers analyze comparable recent sales in the area.
If you agree to pay $450,000 for a home but the appraisal comes back at $420,000, the lender will only loan based on $420,000. You would need to renegotiate the price or pay the $30,000 difference in cash.
FORECLOSURE
Foreclosure is the legal process by which a lender takes possession of a property when the borrower fails to make mortgage payments. After typically 3–6 months of missed payments, the lender can initiate proceedings. Foreclosure severely damages credit scores and results in the loss of the home and any equity built up.
During the 2008 financial crisis, approximately 3.8 million Americans received foreclosure notices. Many had adjustable-rate mortgages that reset to unaffordable payments when introductory periods expired.
COLLATERAL
Collateral is an asset pledged as security for a loan. In a mortgage, the home itself serves as collateral — if the borrower stops making payments, the lender can seize the property through foreclosure to recover the loan balance. This is why mortgages offer lower rates than unsecured loans.
Because a home serves as collateral, mortgage rates are much lower than personal loan or credit card rates. In 2024, average 30-year mortgage rates were around 7%, while credit card APRs averaged 21–24%.
UNDERWRITING
Mortgage underwriting is the lender's process of evaluating a borrower's risk before approving a loan. Underwriters analyze income, employment history, credit score, debt-to-income ratio, and the property's value to determine whether to approve the loan and at what interest rate.
A borrower with a 780 credit score, stable employment, and a 28% debt-to-income ratio would typically qualify for the best rates. One with a 620 score and 45% DTI might face rejection or significantly higher rates.
A mortgage is likely the largest debt you will ever take on. Principal, amortization, escrow, points, PMI, LTV — these terms directly affect how much your home costs, how long you pay for it, and how much equity you build.
Fixed vs. Adjustable Rate Mortgages
A fixed-rate mortgage locks your interest rate for the entire loan term — typically 15 or 30 years. Your principal and interest payment never changes, providing predictability. A adjustable-rate mortgage (ARM) offers a lower initial fixed rate for 5, 7, or 10 years, then adjusts periodically based on a market index plus a margin. ARMs make sense if you plan to sell or refinance before the adjustment period. The 30-year fixed represents approximately 70-80% of all US originations.
Down Payment, LTV, and Private Mortgage Insurance
The loan-to-value ratio (LTV) is the loan amount divided by the home's appraised value. Down payments below 20% trigger Private Mortgage Insurance (PMI) — an added monthly premium of 0.5-1.5% of the loan amount annually, protecting the lender against default. PMI is automatically cancelled when LTV reaches 78% through payments; you can request cancellation at 80% LTV. On a $400,000 loan, PMI might add $150-$500/month to your payment.
Points, Closing Costs, and the Break-Even Calculation
Mortgage points (discount points) are upfront fees to permanently lower your rate — 1 point equals 1% of the loan amount and typically reduces the rate by 0.25%. The break-even analysis: divide the point cost by the monthly payment savings to find how many months until the cost pays for itself. Closing costs typically total 2-5% of the loan amount, covering origination fees, appraisal, title insurance, and prepaid items.

Frequently Asked Questions About Mortgage Terms
How much house can I actually afford?
The traditional rule is that housing costs (PITI: principal, interest, taxes, insurance) should not exceed 28% of gross monthly income, with total debt payments below 36-43%. Many advisors recommend more conservative targets of 20-25% of take-home pay. Factor in maintenance (typically 1-2% of home value annually), HOA fees, and the opportunity cost of a large down payment.
What is an escrow account in a mortgage?
An escrow account is a holding account managed by your mortgage servicer that collects a portion of your monthly payment to cover property taxes and homeowners insurance when they come due. Instead of a $6,000 tax bill twice a year, you pay $500/month into escrow. Escrow accounts are required by most lenders when LTV exceeds 80%.
What is refinancing and when does it make sense?
Refinancing replaces your existing mortgage with a new loan, typically to get a lower rate, change the term, or access equity. Refinancing generally makes sense when you can reduce your rate by at least 0.75-1% and plan to stay long enough to recoup closing costs. Divide closing costs by monthly payment savings to find your break-even point.
What does being pre-approved for a mortgage mean?
Pre-approval is a formal evaluation by a lender resulting in a conditional commitment to lend up to a specified amount. It requires a hard credit inquiry and documentation of W-2s, tax returns, bank statements, and pay stubs. Pre-approval differs from pre-qualification, which is a softer estimate. In competitive markets, sellers often require pre-approval letters before accepting offers. They are typically valid for 60-90 days.
What is PMI and how do I avoid it?
Private Mortgage Insurance is required when your down payment is less than 20% on a conventional loan. It protects the lender — not you. PMI costs 0.5-1.5% of the loan annually. To avoid PMI: make a 20% down payment, use a piggyback loan (80-10-10 structure), or choose lender-paid PMI. VA loans and USDA loans do not require PMI regardless of down payment size.
