Key Mortgage and Real Estate Terms for Real Estate Investors in the U.S.
Your go-to guide for understanding key real estate and mortgage terms. Each definition is written in clear, simple language to make complex topics easy to grasp, whether you’re learning the basics or refining your knowledge of the real estate market.
A
Adjustable-Rate Mortgage (ARM)
An adjustable-rate mortgage is a home loan where the interest rate is fixed for a set number of years and then adjusts periodically based on market conditions. This means your monthly payment can change over time.
Example: With a 5/1 ARM, the interest rate is fixed for the first five years. After that, it adjusts once a year, so if market rates rise, your payment will too.
Amortization
Amortization is the process of paying off a mortgage through monthly installments that cover both the loan balance (principal) and interest. At the start, most of your payment goes toward interest, but over time more goes toward principal.
Example: On a $250,000 loan, the first few years mostly cover interest. By year 20, most of the monthly payment reduces the loan balance, helping you build equity faster.
Annual Percentage Rate (APR)
The APR is the total yearly cost of borrowing money. It includes the loan’s interest rate as well as certain lender fees, making it easier to compare loan offers.
Example: A mortgage might advertise a 6% interest rate, but with $4,000 in fees, the APR works out to 6.3%. This gives a clearer view of the true cost of the loan.
Appraisal
An appraisal is a professional opinion of a home’s market value, ordered by the lender before granting a mortgage. It helps confirm that the property is worth the loan amount.
Example: If you agree to pay $350,000 but the appraisal comes back at $330,000, the lender will base the loan on $330,000, leaving you to cover the $20,000 gap.
Appreciation
Appreciation is the increase in a property’s value over time. It can result from rising demand, improvements, or neighborhood development.
Example: A home bought for $200,000 that grows in value to $260,000 has appreciated by $60,000.
Asset
An asset is anything of financial value that you own, like savings, stocks, or property. Lenders consider assets when evaluating your loan application.
Example: Your savings account, car, and investment portfolio are all assets that can strengthen your mortgage application.
B
Balloon Payment
A balloon payment is a large lump sum due at the end of a loan term. These loans typically have smaller monthly payments at first, followed by one big final payment.
Example: You might take a 7-year loan with low monthly payments, but at the end of year 7, you owe the remaining $150,000 all at once.
Basis Points (BPS)
A basis point is a unit equal to 0.01% and is used to describe interest rate changes.
Example: If your rate increases from 6.00% to 6.25%, that is a rise of 25 basis points.
Borrower
The borrower is the person who takes out a loan and is responsible for repaying it.
Example: If you and a spouse buy a home together, both of you may be listed as borrowers on the mortgage.
Bridge Loan
A bridge loan is a short-term loan that helps you buy a new home before selling your current one.
Example: You use a bridge loan for the down payment on a new house, then pay it off once your old house sells.
Broker
A broker is a licensed professional who helps with buying, selling, or financing real estate.
Example: A mortgage broker helps you find the best loan offer, while a real estate broker guides you through a home purchase.
C
Cap Rate (Capitalization Rate)
Cap rate measures the return on a rental property, calculated by dividing net operating income by property value. It helps investors compare deals.
Example: A property worth $500,000 that earns $50,000 in net income has a 10% cap rate.
Cash-Out Refinance
This is when you replace your mortgage with a larger one and take the difference in cash.
Example: If you owe $150,000 on a $300,000 house and refinance for $200,000, you receive $50,000 cash to use for renovations or other needs.
Closing
Closing is the final step in a real estate deal, where ownership officially transfers to the buyer.
Example: At closing, you sign loan documents, pay closing costs, and receive the keys to your new home.
Closing Costs
Closing costs are the fees and expenses paid when finalizing a home purchase, usually between 2% and 5% of the loan amount.
Example: On a $400,000 home, closing costs may total around $12,000.
Collateral
Collateral is property pledged to secure a loan. If the borrower defaults, the lender can seize it.
Example: With a mortgage, the home itself is the collateral.
Conforming Loan
A conforming loan meets the size limits and guidelines set by Fannie Mae and Freddie Mac.
Example: In 2025, most US counties have a conforming loan limit of $766,550.
Conventional Loan
A conventional loan is not backed by the government, unlike FHA or VA loans.
Example: Buyers with good credit and a 20% down payment often use conventional loans.
Credit Score
A credit score is a number between 300 and 850 that shows your credit history and reliability.
Example: A score of 760 may qualify you for the lowest interest rates, while a score of 620 will usually lead to higher rates.
D
Debt-to-Income Ratio (DTI)
DTI is the percentage of your gross monthly income that goes toward debts, including your mortgage. Lenders use it to assess affordability.
Example: If you earn $6,000 a month and spend $2,000 on debt payments, your DTI is 33%.
Deed
A deed is the legal document that transfers property ownership from one party to another.
Example: At closing, the seller signs the deed to officially transfer ownership to the buyer.
Default
Default occurs when a borrower fails to make mortgage payments as agreed.
Example: If you stop making payments for several months, the lender may declare the loan in default and begin foreclosure.
Down Payment
The down payment is the upfront cash you pay when buying a home, usually a percentage of the purchase price.
Example: On a $300,000 home, a 20% down payment is $60,000.
DSCR Loan (Debt Service Coverage Ratio Loan)
A DSCR loan is often used by real estate investors. Instead of personal income, the loan is based on the property’s ability to generate rental income compared to the debt owed.
Example: If a rental earns $3,000 per month and the mortgage payment is $2,000, the DSCR is 1.5, meaning the income covers the debt comfortably.
E
Earnest Money
Earnest money is a deposit made by the buyer to show good faith when making an offer on a home. It is applied toward the down payment or closing costs if the sale goes through.
Example: You may put $5,000 in escrow as earnest money when your offer is accepted.
Equity
Equity is the difference between a home’s market value and the amount still owed on the mortgage.
Example: If your house is worth $400,000 and you owe $250,000, your equity is $150,000.
Escrow
Escrow is a neutral third party that holds money or documents during a real estate transaction until all conditions are met.
Example: Your lender may set up an escrow account to collect property taxes and insurance along with your mortgage payment.
1031 Exchange
A 1031 exchange lets investors defer capital gains taxes by reinvesting proceeds from one property sale into another like-kind property.
Example: You sell a rental property for $500,000 and use a 1031 exchange to buy another, avoiding immediate capital gains taxes.
F
Fair Market Value (FMV)
Fair market value is the price a property would sell for on the open market, under normal conditions, with a willing buyer and seller.
Example: If similar homes in your neighborhood recently sold for $400,000, that is likely close to the fair market value of your home.
Fannie Mae
Fannie Mae is a government-sponsored enterprise (GSE) that buys mortgages from lenders, providing them with liquidity to issue more loans.
Example: Your lender may sell your mortgage to Fannie Mae after closing, but your loan terms remain the same.
FHA Loan
An FHA loan is a government-backed mortgage insured by the Federal Housing Administration. It is popular with first-time buyers because it allows lower down payments and more flexible credit requirements.
Example: A buyer with a credit score of 620 and a 3.5% down payment may qualify for an FHA loan.
Fixed-Rate Mortgage
A fixed-rate mortgage is a loan where the interest rate stays the same for the entire term, keeping monthly payments predictable.
Example: With a 30-year fixed-rate loan at 6%, your payment stays constant for three decades, regardless of market rate changes.
Foreclosure
Foreclosure is the legal process where a lender takes back a home after the borrower fails to make mortgage payments.
Example: If you miss payments for several months, the lender may foreclose and sell your home to recover the debt.
G
Good Faith Estimate (GFE)
A Good Faith Estimate was a disclosure form that outlined estimated loan costs. It has since been replaced by the Loan Estimate form under new regulations.
Example: Years ago, lenders provided a GFE to show expected fees and terms; today, borrowers receive a Loan Estimate instead.
Gross Rent Multiplier (GRM)
GRM is a quick way investors evaluate a rental property by dividing the property’s price by its annual gross rent.
Example: A $300,000 property generating $30,000 in rent has a GRM of 10. Lower GRMs often indicate better investment potential.
H
Home Equity
Home equity is the difference between your home’s current market value and what you still owe on your mortgage.
Example: If your house is worth $400,000 and you owe $250,000, you have $150,000 in equity
Home Equity Line of Credit (HELOC)
A HELOC is a revolving line of credit secured by your home’s equity, similar to a credit card. You can borrow, repay, and borrow again up to a set limit.
Example: If you have $100,000 in equity, your bank may approve a $50,000 HELOC that you can draw from for renovations or other expenses.
Home Inspection
A home inspection is an evaluation of a property’s condition by a professional inspector before purchase.
Example: A home inspection may reveal issues like roof damage or plumbing leaks, which you can negotiate with the seller to fix.
I
Interest Rate
The interest rate is the percentage charged by a lender on the principal balance of a loan. It directly affects the size of your monthly payment.
Example: A $200,000 loan at 6% interest costs more each month than the same loan at 5%.
Investor Loan
An investor loan is a mortgage designed for people buying properties to rent out or flip, rather than to live in.
Example: If you buy a duplex to rent both units, you would likely need an investor loan instead of a standard owner-occupied mortgage.
Inflation Hedge (Real Estate)
Real estate is often considered an inflation hedge because property values and rents tend to rise with inflation.
Example: As inflation pushes prices up, your fixed-rate mortgage stays the same while rents and property values increase, protecting your investment.
J
Joint Tenancy
Joint tenancy is a way for two or more people to own property together, with equal shares and survivorship rights. If one owner dies, their share automatically passes to the surviving owner(s).
Example: If two siblings own a home as joint tenants and one passes away, the surviving sibling becomes the sole owner.
Jumbo Loan
A jumbo loan is a mortgage that exceeds the conforming loan limits set by Fannie Mae and Freddie Mac. Because it is larger, it usually requires higher credit scores and larger down payments.
K
Key Rate
The key rate is the interest rate set by the Federal Reserve, which influences overall borrowing costs across the economy. Mortgage rates often move in response to changes in the key rate.
Kick-Out Clause
A kick-out clause is a provision in a real estate contract that allows a seller to continue showing the property and accept another offer if the buyer cannot remove certain contingencies.
L
Lien
A lien is a legal claim on a property used as collateral for a debt. The lien must be paid off before the property can be sold.
Liquidity
Liquidity refers to how quickly an asset can be converted into cash without losing value. Real estate is typically less liquid than other assets.
Loan-to-Value Ratio (LTV)
LTV compares the loan amount to the property’s appraised value. Lenders use it to measure risk.
Example: Buying a $300,000 home with a $60,000 down payment means borrowing $240,000. The LTV is 80%.
Lock-In Rate
A lock-in rate is an agreement with your lender to keep a specific mortgage interest rate for a set period while your loan is processed.
Example: If rates are rising, locking in a 6% rate for 60 days ensures your loan won’t be affected before closing.
M
Market Value
Market value is the estimated amount a property would sell for under normal conditions.
Example: If similar homes in your area are selling for $400,000, that is likely close to your property’s market value.
Mortgage
A mortgage is a loan from a lender used to buy real estate, where the property itself acts as collateral.
Example: If you borrow $250,000 to buy a home, the bank holds a lien until the mortgage is fully paid.
Mortgage-Backed Securities (MBS)
MBS are investments made up of bundled mortgage loans that are sold to investors. They provide lenders with liquidity to issue new loans.
Multiple Listing Service (MLS)
The MLS is a database of properties for sale, accessible to licensed real estate agents and brokers.
N
Negative Amortization
Negative amortization occurs when loan payments are not enough to cover the interest, causing the balance to grow.
Example: If your mortgage requires a $1,200 interest payment but you only pay $1,000, the extra $200 is added to your loan balance.
Net Operating Income (NOI)
NOI is the income from a rental property after subtracting operating expenses but before paying mortgage costs.
Example: If your property earns $50,000 in rent and has $15,000 in expenses, the NOI is $35,000.
Non-QM Loan (Non-Qualified Mortgage)
A non-QM loan is a mortgage that doesn’t meet traditional lending standards but allows more flexibility for borrowers with unique situations.
Notary Public
A notary public is an official who verifies identities and witnesses the signing of important documents.
O
Offer
An offer is a formal proposal from a buyer to purchase a property under specific terms.
Example: You may offer $380,000 on a home listed at $400,000, with the seller deciding whether to accept, reject, or counter.
Origination Fee
An origination fee is a lender’s charge for processing a new mortgage. It is usually a percentage of the loan amount.
Example: On a $250,000 mortgage, a 1% origination fee would cost $2,500.
Owner’s Title Insurance
This insurance protects the buyer from future ownership disputes or title issues with the property.If someone later claims they inherited the property you purchased, owner’s title insurance covers the legal costs of defending your ownership.
P
PITI (Principal, Interest, Taxes, and Insurance)
PITI is the total monthly cost of a mortgage, including the loan repayment, interest, property taxes, and homeowners insurance. Lenders use it to determine if you can afford a loan.
Example: On a $1,500 mortgage payment, $900 may go to principal and interest, $400 to property taxes, and $200 to insurance.
Point (Mortgage Point)
A point is a fee you pay to reduce your mortgage interest rate. One point usually equals 1% of the loan amount.
Example: On a $200,000 loan, one point costs $2,000. Paying it upfront could reduce your interest rate from 6.5% to 6.25%.
Pre-Approval
Pre-approval is a lender’s commitment stating how much they are willing to lend you based on your financial information. It strengthens your buying position.
Example: With a pre-approval letter for $400,000, sellers know you are a serious buyer with financing ready.
Prepayment Penalty
A prepayment penalty is a fee charged if you pay off your mortgage early. Not all loans have this clause. If you refinance or sell within three years of taking a loan, you might owe a penalty equal to several months of interest.
Principal
Principal is the original loan amount you borrow, not including interest. Each payment reduces the principal balance.
Example: On a $250,000 loan, if you pay $1,500 this month and $400 goes toward principal, your balance drops to $249,600.
Private Mortgage Insurance (PMI)
PMI protects lenders when borrowers make down payments smaller than 20%.
Example: If you buy a $300,000 home with 10% down, you may pay $100–$200 a month for PMI until your equity reaches 20%.
Property Taxes
Property taxes are annual fees charged by local governments, usually based on a home’s assessed value.
Example: If your city charges 1.2% and your home is worth $300,000, your yearly property tax is $3,600.
Q
Qualifying Ratios
These are calculations lenders use to measure whether a borrower can afford a mortgage, usually based on income, debts, and housing expenses. A common rule is that housing costs should not exceed 28% of gross monthly income.
Quiet Title
A quiet title is a legal action used to settle disputes and establish clear property ownership. If two parties claim rights to the same land, a quiet title lawsuit may determine the rightful owner.
R
Refinance
Refinancing replaces your current mortgage with a new one, often to secure a lower rate or better terms.
REIT (Real Estate Investment Trust)
A REIT is a company that owns or finances income-generating real estate and allows individuals to invest without directly owning property.
REO (Real Estate Owned)
REO refers to property owned by a lender after foreclosure when it fails to sell at auction.
Reverse Mortgage
A reverse mortgage allows homeowners aged 62 or older to convert home equity into cash while continuing to live in the home.
Example: A retiree with a $300,000 home may receive monthly payments from the lender, which are repaid when the home is sold.
Right of First Refusal
This gives someone the first chance to buy a property before the seller accepts other offers. A tenant may have the right of first refusal if their landlord decides to sell the building.
S
Second Mortgage
A second mortgage is an additional loan taken against a property that already has a mortgage.
Example: A homeowner with $100,000 equity may borrow $50,000 as a second mortgage for renovations.
Seller’s Market
A seller’s market occurs when housing demand is higher than supply, giving sellers more negotiating power.
Short Sale
A short sale is when a home sells for less than the balance owed on the mortgage, with lender approval.
Example: A homeowner who owes $250,000 might sell for $220,000 if the lender accepts the loss.
Survey
A survey maps a property’s boundaries and features. Lenders often require one before closing.
T
Tax Lien
A tax lien is a legal claim by the government against a property when the owner fails to pay taxes.
Example: If you owe $10,000 in unpaid property taxes, a lien may be placed on your home until it’s paid.
Tenancy in Common (TIC)
TIC is a form of property ownership where two or more people share ownership, but their shares can be unequal. Each owner can pass their share to heirs.
Title
The title is the legal right to own, use, and sell property.
Title Insurance
Title insurance protects against ownership disputes, liens, or errors in property records.
Transfer Tax
Transfer tax is a fee charged by state or local governments when property changes hands.
Example: On a $400,000 home, a 1% transfer tax means you pay $4,000 at closing.
Trust Deed
A trust deed is a document that secures a loan by transferring property title to a trustee until the debt is repaid.
U
Underwriting
Underwriting is the process where a lender reviews your finances, credit, and property details to decide whether to approve your loan. During underwriting, the lender checks your income, assets, debts, and credit history to confirm you can handle the mortgage.
Underwater Mortgage
An underwater mortgage means you owe more on your loan than your home is currently worth.
Example: If your mortgage balance is $280,000 but your home’s value drops to $250,000, your loan is underwater.
Uniform Residential Loan Application (URLA)
This is the standard application form lenders use to collect borrower information for mortgage approval.
Example: When applying for a mortgage, you complete the URLA with details about your income, employment, assets, and debts.
V
VA Loan
A VA loan is a government-backed mortgage available to eligible veterans, active-duty service members, and some surviving spouses. It requires no down payment or PMI.
Example: A veteran buying a $300,000 home may qualify for a VA loan with no down payment and lower closing costs.
Vacancy Rate
Vacancy rate is the percentage of rental units that are unoccupied in a given area or property.
Example: If an apartment building has 20 units and 2 are empty, the vacancy rate is 10%.
Variable Interest Rate
A variable interest rate changes over time, usually tied to a benchmark index.
Example: If your mortgage starts at 5% but is tied to market rates, it may rise to 6% when rates increase.
W
Warranty Deed
A warranty deed guarantees that the seller owns the property free and clear and has the right to sell it.
Wraparound Mortgage
A wraparound mortgage is a type of loan where a new lender takes over the existing mortgage while issuing a new one, combining both balances.
Example: If you owe $100,000 on a home and sell it for $200,000, the buyer might take a wraparound mortgage where they pay you, and you continue paying the original lender.
Walk-Through
A walk-through is the final inspection a buyer makes before closing on a home to ensure it is in the agreed-upon condition.
Y
Yield
Yield is the income return on an investment, usually expressed as a percentage of the investment’s cost or value.
Example: If you buy a rental property for $200,000 and earn $20,000 in annual income, your yield is 10%.
Yield Maintenance
Yield maintenance is a prepayment penalty that ensures a lender receives the same return as if the borrower had not paid off the loan early.
Z
Zoning
Zoning refers to local government regulations that control how land can be used. A property zoned for residential use cannot be used for commercial purposes without approval.
Zero-Down Mortgage
A zero-down mortgage allows a borrower to buy a home without making a down payment. These are rare and usually offered under special programs.
