Mortgage terminology is the vocabulary lenders, underwriters, and title companies use to describe your loan, and roughly 25 terms do almost all the work on a Loan Estimate and Closing Disclosure.

Most sort into four buckets: the loan’s structure, your risk as a borrower, money held or paid on your behalf, and the closing table itself. Knowing which bucket a word belongs to tells you what it can change about your payment. Nobody is born knowing what “impounds” means.

Learn more about mortgage terminology, including how your loan is built, what money is held on your behalf, and the terms you’ll meet at the closing table.

Key takeaways:

• Four buckets: Nearly every mortgage term describes one of four things, the loan’s structure, your risk profile, money held on your behalf, or a closing document.
• Three terms move your payment most: Loan-to-value ratio, escrow, and mortgage insurance explain most of the gap between the payment you expected and the one you were quoted, and a 5% swing in loan-to-value can add or remove mortgage insurance.
• Where to check your own numbers: Every lender’s Loan Estimate uses these terms in the same order on the same federal form, which is what makes side-by-side comparison possible, and why Align shops one scenario across several lenders.

What mortgage terminology do you actually need to know?

Mortgage terminology is the standardized vocabulary used across loan disclosures, and because the federal forms are identical from lender to lender, learning about 25 terms lets you compare any two offers line by line. The CFPB’s Loan Estimate explainer walks the form box by box. Four buckets cover nearly everything:

• Structure terms: Principal, term, amortization, points, rate lock, what you pay, and for how long.
• Borrower terms: Credit score, debt-to-income, loan-to-value, reserves, approval and price.
• Money-held terms: Escrow, prepaids, impounds, mortgage insurance, why your payment beats principal and interest.
• Closing terms: Title commitment, clear to close, funding, recording, process, not pricing.

Sort before you define. Everything below sits inside our Mortgage Basics pillar.

Terms that describe how your loan is built

The first four decide your payment before tax or insurance is added.

• Principal: The amount you borrowed, not counting interest. Every payment shaves a little off; what’s left is your balance.
• Interest: The lender’s charge for the money, calculated monthly on the balance you still owe.
• Term: How many years you have to repay, usually 30 for a lower payment, 15 for a lower total cost.
• Amortization: The schedule splitting each payment between interest and principal. Interest is charged on the balance, so the interest slice is largest early. Which is why extra principal is worth most then. See mortgage amortization.
• Fixed-rate vs. adjustable-rate: A fixed rate never changes. An adjustable rate holds for an intro period, commonly 5, 7, or 10 years, then moves within caps in your note. Compare fixed- vs. adjustable-rate mortgages.
• Discount points: Prepaid interest that buys your rate down. One point equals 1% of the loan amount, so a point on a $300,000 loan costs $3,000 at closing.¹ The question is whether you’ll hold the loan long enough to break even.
• Origination fee: What the lender charges to make the loan, shown in Section A of your Loan Estimate. Compare Section A across quotes.
• Annual percentage rate (APR): The rate plus most lender fees as one yearly figure. A low rate with high fees can carry a higher APR than a higher rate with none.
• Rate lock: A commitment to hold your quoted pricing for a set window, commonly 30 – 60 days. Extensions cost money, as our mortgage rate lock guide explains.
• Conforming vs. non-conforming: A conforming loan fits the size and underwriting rules Fannie Mae and Freddie Mac will buy. Anything outside them, jumbo included, is non-conforming.

Our How Mortgages Work hub takes these apart one at a time.

Terms that describe you as a borrower

Three ratios decide most approvals: credit score, debt-to-income, and loan-to-value.

Loan-to-value ratio (LTV)

Your loan-to-value ratio is the loan amount divided by the home’s value, using the appraised value or purchase price, whichever is lower. Borrow $285,000 on a $300,000 Waterford home and your loan-to-value ratio is 95%.¹ LTV sets the mortgage insurance rules: on a conventional loan you may ask your servicer to cancel private mortgage insurance when your balance is scheduled to reach 80% of original value, and the servicer must terminate it automatically at 78%. Fannie Mae’s standard 97% LTV option runs the other way, allowing 3% down when at least one borrower is a first-time home buyer.

Debt-to-income ratio (DTI)

Your debt-to-income ratio is total monthly debt divided by gross monthly income. Fannie Mae’s automated underwriting allows a maximum DTI of 50% on the conventional files it approves; manual underwriting is tighter, with a 36% baseline stretching to 45% when credit score and reserves meet the higher bar.

Credit score, tri-merge, and the middle score

Lenders don’t use one score. They pull a tri-merge report and qualify you on your representative score, the middle of three, or the lower of two. With more than one borrower, Fannie Mae’s Selling Guide has the lender use the average median credit score across the borrowers for loan eligibility, which is why a co-borrower with strong income but weak credit can still pull your pricing down. See what counts as a good credit score to buy a house and our Credit & Qualifying hub.

Reserves, seasoning, and sourcing

All three answer one underwriter question: where did this money come from, and will it still be there? Reserves are the assets left after your down payment and closing costs, measured in months of housing payments, lenders in Align’s network commonly want a couple of months. Sourcing documents where a deposit came from; Fannie Mae defines a large deposit needing explanation as one exceeding 50% of monthly qualifying income. Seasoning is the waiting period before something counts, covered in our mortgage underwriting guide.

Terms that describe money held or paid for you

These terms explain why your payment is bigger than principal and interest, often by hundreds a month.

Escrow

Escrow means a neutral third party holds money until a deal’s conditions are met, and one word covers two things. Escrow during the purchase is a title company holding your earnest money. An escrow account afterward is your servicer collecting taxes and insurance monthly and paying those bills. Our guide to escrow and how it works covers both.

Prepaids and impounds

Prepaids are items you fund at closing before they’re due, the first year of homeowners insurance, interest through month-end, and the initial escrow deposit. “Impounds” is regional slang for that account. Federal rules cap the cushion a servicer may hold at one-sixth of the account’s estimated annual disbursements, two months of your escrow payments. Our Payments, Escrow & Servicing hub picks up after you close.

PMI, MIP, and the VA funding fee

All three protect the lender when you put less than 20% down, and each program names its version differently. Private mortgage insurance (PMI) is the conventional version and ends under the 80% and 78% rules above. Mortgage insurance premium (MIP) is FHA’s: 1.75% of the base loan amount upfront, plus an annual premium running 11 years when the loan started at 90% LTV or less, and the full term above that.² The VA funding fee replaces monthly mortgage insurance entirely, 2.15% for most first-time users putting less than 5% down, financeable, and waived for veterans receiving VA compensation for a service-connected disability.³ Our guide to mortgage insurance compares monthly costs.

PITI

PITI is shorthand for the whole housing payment: principal, interest, taxes, and insurance. Compare that number against your rent, not the principal-and-interest figure a quote leads with. Homeowners association dues sit outside PITI but still count in your debt-to-income ratio.

Terms you’ll meet at the closing table

Closing vocabulary is process words with deadlines attached, and two of those deadlines are federal law.

• Loan Estimate: The standardized form showing your rate, projected payment, and closing costs. Your lender must provide it within three business days of your application.
• Closing Disclosure: The final version of those numbers. Lenders must provide your Closing Disclosure three business days before closing. A window that exists so you can compare it against your Loan Estimate.
• Earnest money: The good-faith deposit you post when your offer is accepted, held in escrow and credited back at closing. Our explainer on earnest money deposits covers when it’s refundable.
• Title commitment and title insurance: The commitment lists what must be cleared first, liens, unpaid taxes, boundary problems. The policy covers ownership claims that surface later, which is why title insurance is a cost you hope to forget.
• Appraisal vs. inspection: The lender orders an appraisal to confirm the home is worth what you’re borrowing. You order an inspection to learn what’s wrong with it.
• Clear to close: The underwriter’s sign-off that every condition is satisfied and documents can be drawn.
• Funding and recording: Funding is the wire that pays the seller; recording is the county filing that makes the transfer public. Our closing costs breakdown itemizes both.
• First payment date: Usually the first of the month after a full month passes, which is why closing late in a month pushes it out.

Mortgage terminology at a glance

Eight terms carry most of the meaning in a loan file. The middle column defines each; the right column is what it changes.

Term	What it means in one line	What it changes for you
Amortization	How each payment splits between interest and principal	Why early payments barely move the balance
Discount point	A fee equal to 1% of the loan, paid to lower your rate	Cash now, smaller payment later
APR	The rate plus most lender fees, as one yearly figure	The number to compare across quotes
Loan-to-value (LTV)	Loan amount divided by the home’s value	Drives mortgage insurance and pricing
Debt-to-income (DTI)	Monthly debt divided by gross income	Sets your borrowing ceiling
Escrow account	A servicer-held account for taxes and insurance	Why a “fixed” payment still changes
PMI	Insurance protecting the lender on low-down-payment loans	Cancellable at 80% LTV, ends at 78%
PITI	Principal, interest, taxes, and insurance	The number to compare against rent

What Michigan buyers should know

Three Michigan terms change the math on an ordinary file, and all three land in escrow.

• Principal Residence Exemption (PRE): Michigan’s Principal Residence Exemption exempts your home from the local school operating millage, up to 18 mills, hundreds of dollars a year on the escrowed tax portion of your payment. File the affidavit with your assessor by June 1 for the next summer levy, or November 1 for the winter levy.
• Summer and winter tax bills: Michigan bills property taxes twice a year, with collection dates set locally by charter. That split is why a Michigan escrow account often looks mistimed in its first 12 months, see mortgage escrow accounts for the annual analysis that corrects it.
• Land contract: A seller-financed conveyance still common in parts of Michigan, where the buyer pays the seller directly and the seller keeps title until the balance is paid.

FAQ: Mortgage terminology

Here are answers to common questions about mortgage terminology.

What’s the difference between prequalification and preapproval?

A prequalification is an estimate based on what you tell the lender; a preapproval is a decision based on documents the lender has verified. Prequalification takes minutes and carries almost no weight in a competitive offer. A fully underwritten preapproval, where an underwriter has reviewed your income, assets, and credit, is the version listing agents take seriously. See prequalified vs. preapproved, then ask which one you hold.

Is escrow the same thing as an escrow account?

No. “Escrow” during a purchase means a neutral third party is holding your earnest money and documents until closing. An “escrow account” is different: a servicer-held account that collects a slice of your property taxes and homeowners insurance with every payment, then pays those bills. Our explainer on the role of escrow in home buying covers the purchase side.

What does seasoning mean on a mortgage?

Seasoning is the waiting period a lender requires before something counts. It shows up in three places: funds seasoning on recent deposits; ownership seasoning, where a conventional cash-out refinance requires a borrower on title for six months while FHA requires 12 months of owner-occupancy; and credit-event seasoning after a bankruptcy or foreclosure. Think of it as a cooling-off period for your file.

What is a land contract in Michigan?

A land contract is a seller-financed purchase in which the buyer pays the seller directly and the seller keeps legal title until the balance is paid off. They remain common in parts of Michigan, especially on lower-priced homes. The tradeoff: payments usually aren’t reported to the credit bureaus, and you don’t hold title until the end. Refinancing out of one is a scenario Align places regularly, see alternative financing options.

The bottom line on mortgage terminology

Mortgage terminology sorts into four buckets, how the loan is built, how a lender reads your risk, what money is held for you, and what happens at closing, and roughly 25 terms carry every disclosure you’ll sign. The three that move your payment most are loan-to-value, escrow, and mortgage insurance: on a conventional loan you can request PMI cancellation at 80% of original value, and your servicer must terminate it at 78%. Learn the buckets, and any Loan Estimate becomes readable. Because Align is an independent broker rather than a lender, the Loan Estimates we put in front of you come from competing wholesale lenders on the same scenario. The vocabulary above is what lets you read the differences.
