Mortgage and Lending Terms

Read up on these 50 mortgage lending terminology before acquiring a loan to move through the process smoothly and confidently.

5/1 Adjustable Rate Mortgage (ARM)

ARM is a type of mortgage with an initial fixed-rate period of five years, followed by annual adjustments based on an index plus a margin. It is often used to purchase or refinance a home.

Other common fixed periods are 3, 7, and 10 years, while 1 signifies the rate adjustment period.

Ability-to-Pay Rule (APR)

APR requires mortgage lenders to ensure borrowers can repay their loans before granting them. It protects borrowers from taking on unsustainable debt. It considers income, credit history, employment, and other factors when evaluating the ability to pay.

Adjustable Rate Mortgage (ARM)

An ARM is a loan with an interest rate that may change periodically. It is structured with fixed period rates followed by a variable period where rates can adjust up or down depending on market conditions.


It is the process of repaying debt in equal amounts over time. A portion of each payment is applied to the loan principal and the interest. As the debt amortizes, the amount paid toward the principal begins small and gradually increases month by month.

Annual Percentage Rate (APR)

An APR is a number that expresses the total annual cost of borrowing money as a percentage of the loan amount. The APR on a loan or credit card is intended to provide a clear picture of how much it costs to borrow money.


It is an estimate of the value of a property done by a licensed appraiser. It informs potential lenders of the amount they may be willing to loan on a piece of real estate. It also identifies issues that may decrease a property's value, like safety concerns or structural damage.

Balloon Loan

It involves making relatively small payments for a certain period of time and then one large payment to cover the remaining balance when the loan matures. The balloon payment comes due at the end of a loan’s term or after a set number of payments have been made.

Closing Costs

These are fees for finalizing a loan, like an appraisal, credit report fee, title search, title insurance, and attorney’s fees. Closing costs can vary widely depending on the location, lender, and type of mortgage. It can range from 2% to 6% of the total loan value.

Closing Disclosure

This five-page document outlines all the costs associated with a loan. It details the payment terms, interest rates, closing costs, and other fees a borrower must pay at the closing table. Lenders must give borrowers at least three days to review the closing disclosure.


A co-borrower has equal responsibility for a loan taken out; they may or may not live in the same residence as the borrower. But they are equally liable to repay the debt. Generally, both borrower and co-borrower must meet all credit criteria to qualify for a mortgage.

Credit History

This pertains to all information about an individual’s borrowing and repayment activities. It is compiled from different sources, including credit bureaus, banks, landlords, employers, and other entities that have previously extended credit or loaned money to a person.

Credit Report

This is a detailed record of your credit history. It includes information about the types of accounts held, payment history, credit limits, outstanding balances, and other details related to loans or lines of credit. Lenders use it to assess your creditworthiness.

Credit Score

Credit score is a three-digit number, typically ranging from 300-850, used to measure a person's creditworthiness. It considers a borrower’s credit history and is provided by one of the three major credit bureaus: Experian, Equifax, and TransUnion.

A higher credit score increases your chances of loan approval and getting favorable interest rates.

Debt-to-Income (DTI) Ratio

This is the percentage of an individual’s income that goes towards paying debts. It considers all debt, including mortgage payments, student loans, credit cards, and other obligations.

Generally, the highest DTI ratio a borrower can have and still qualify for a mortgage is 43%. Lenders prefer a DTI of less than 36%, with no more than 28% of that debt dedicated to mortgage or rent payments.

This happens when a borrower fails to make payments on their loan. After several missed payments, lenders can declare the loan in default and start the process of foreclosure or other remedies to collect on the loan. A default can have a long-term effect on your credit score.

Down Payment

The amount of money that you pay upfront when taking out a mortgage. Down payments reduce the total amount borrowed and usually range between 10-20% of a home’s purchase price. A higher down payment may help decrease loan interest rates.

Earnest Money Deposit (EMD)

An EMD is a fixed amount a buyer provides when making an offer on the house. It shows good faith and buyer seriousness and helps to protect both parties in a real estate transaction. If the sale goes through, an EMD is put toward the down payment and closing costs.


The equity is the amount of the home a borrower owns outright. It is calculated by subtracting the remaining balance on the mortgage loan from the home’s current market value.


Escrow is a legal arrangement in which a third party temporarily holds money or property until a specific condition, such as a purchase agreement, is completed.

Fannie Mae purchases mortgages from larger commercial banks and offers loan guarantees, helping to keep interest rates low.

Home Appraisal

It is an evaluation to determine the value of a property in the current market. The appraiser will look at comparable sales, location, and the home’s condition to determine an amount that accurately reflects its worth.

Home appraisals are required for most mortgage loans and are paid for by the borrower.

Homeowners Insurance

This insurance covers home damages, including contents in a disaster. It also covers liability for any injury or property damage caused by tenants on the property. Lenders typically require homeowners insurance when providing financing on a home purchase.

Loan Estimate

This three-page federal form outlines the key terms of a home loan. It includes the estimated interest rate, monthly payment, key dates, closing costs, processing time, and funds available after closing.

Loan-to-Value (LTV) Ratio

This is a measure of how much money you are borrowing compared to the purchase price or appraised value of a home, expressed as a percentage. A higher down payment lowers the LTV ratio. It may affect whether a lender will require private mortgage insurance (PMI) to be paid.


A mortgage is a loan used to purchase, refinance, or borrow against real estate. The loan is secured by the property and is typically paid back over some time with interest. Mortgages allow borrowers to purchase homes without paying the total cost upfront.

Mortgage Insurance

This insurance policy helps protect lenders against losses due to a borrower’s default. Usually, mortgage insurance is required when borrowers cannot put down a 20% deposit on their loan.

Mortgage Term

This refers to the length of time over which a borrower commits to repay a loan. It can range anywhere from 1 to 30 years. The longer the term, the lower the monthly payments will be, but the higher the total amount of interest to pay over the life of the loan.

Origination Fee

This is a fee charged by a mortgage lender for processing your loan. It is usually around 0.5%-1.0% of your overall loan sum. Almost all lenders impose origination fees to cover the costs of processing, underwriting, and executing your loan.

PMI is a policy that protects the lender if the borrower defaults on their loan. It is usually required on loans with down payments of less than 20%. It can range from 0.5% to 2.0%.

Generally, the smaller the down payment, the higher the PMI rate.

Property Taxes

These are local or state taxes assessed on a property’s value. They vary by locality and must be paid annually, typically in two installments. Property tax payments may need to be escrowed into the monthly mortgage payment to ensure they are paid on time.

Qualified Written Request (QWR)

A QWR is a document sent by a homeowner to their mortgage servicer that initiates an official investigation into any errors, fees, or other problems with a mortgage loan. It is a formal way of requesting information or for a servicer to address any issues with an account.
