Buying a home in Washington means learning a few mortgage acronyms that show up quickly once you start comparing lenders and loan options. These terms can help you make sense of rate quotes, monthly payment estimates, approval conversations, and down payment decisions.
“Will you need PMI because of your LTV, and how does your APR affect your ARM?” Say what?
Banks and mortgage lenders often use industry acronyms that leave borrowers scratching their heads. First-time home buyers, in particular, can have a hard time wading through the alphabet soup. So we thought it would be helpful to explain some of the most common mortgage acronyms in Washington you’re likely to encounter when buying a home — and why they matter when you’re choosing a loan.
The APR, or annual percentage rate, represents the full cost of a mortgage loan. It includes the interest rate plus any other fees and points you might encounter during the lending process. Because of these added “ingredients,” the APR is usually higher than the actual mortgage rate that’s applied to your loan. It’s also a good way to understand the full cost. When you compare loan offers, APR gives you a more useful apples-to-apples view than rate alone, so it can help you spot which option may cost more over time.
An adjustable-rate mortgage loan, or ARM, has an interest rate that can change or adjust over time. And it might go up or down, depending on market conditions at the time of adjustment. This makes the ARM different from the fixed-rate mortgage (FRM), which carries the same interest rate for the life of the loan. While the FRM is more popular among home buyers in Washington, the ARM can be useful in certain scenarios. Borrowers usually compare ARM terms when deciding between a lower initial payment and the possibility of future rate changes.
The debt-to-income ratio, or DTI, is a tool lenders use when reviewing applicants for a mortgage loan. As the name suggests, it compares (A) the amount of money a person spends on recurring debts, and (B) the amount of money he or she earns each month. Debt-to-income limits can vary by loan program and lender criteria, so borrowers may encounter different thresholds depending on the mortgage they choose. You’ll most often hear about DTI during pre-approval and underwriting, because it affects how much you may be able to borrow and whether you qualify at all.
Home loans that are insured by the Federal Housing Administration are referred to as FHA loans. The program is popular with first-time buyers, though it’s not limited to that group. The FHA (part of HUD) insures loans against default-related losses, giving lenders an added layer of protection.
As a result, the qualification requirements for borrowers can be a bit more relaxed. Home buyers can make a down payment as low as 3.5% with this program. In contrast, a mortgage loan that’s not insured by the government is referred to as a “conventional” loan. Borrowers often compare FHA with conventional financing when weighing credit flexibility, down payment options, and overall loan fit.
The loan-to-value ratio, or LTV, is another important concept that home buyers in Washington should know about. This number, usually expressed as a percentage, compares the amount of money you are borrowing (or your outstanding loan balance) to the home’s market value.
For example, a homeowner with a $200,000 loan balance on a property that’s worth $250,000 has an LTV of 80%. When the loan-to-value for a conventional mortgage rises above 80%, private mortgage insurance is usually required (see “PMI” below). LTV matters most when planning your down payment, because it can affect both your loan options and whether added mortgage insurance is likely.
We covered PITI in a recent article. This acronym is used to describe the four components that make up a typical mortgage payment. In order, the letters stand for principal, interest, taxes and insurance.
Insurance can refer to both homeowners insurance and, for some borrowers, mortgage insurance. This is another important acronym for home buyers in Washington to understand. You’ll often see PITI in payment estimates, affordability discussions, and budgeting conversations because it gives a fuller picture of the monthly housing cost than principal and interest alone.
Private mortgage insurance, or PMI, is usually required for home loans with an LTV higher than 80%. In other words, if your loan accounts for more than 80% of the current property value, you’ll probably have to have mortgage insurance.
But there’s an upside here as well. Without PMI, the typical home buyer in Washington would have to wait a lot longer — and save a lot more money — to make a down payment on a house. Borrowers usually think about PMI when deciding whether to buy sooner with a smaller down payment or wait and put more money down.
These are by no means the only mortgage-related terms out there. But they are some of the most common mortgage acronyms you are likely to encounter when buying a home in Washington state.
These terms are not just glossary words. You’ll commonly see them in lender conversations, rate quotes, payment estimates, pre-approval discussions, and loan comparison documents. Understanding the acronyms can make it easier to ask better questions, compare offers more confidently, and see how a loan choice could affect your payment, approval path, or down payment strategy.

The interest rate is the rate applied to the loan balance, while APR reflects the broader cost of the loan by including the rate plus certain fees and points. That’s why borrowers often use APR when comparing competing offers.
DTI looks at your recurring debts compared to your monthly income. Lenders use it during qualification, and the exact limits can vary by loan program and lender criteria.
PITI stands for principal, interest, taxes, and insurance. It’s commonly used to show a more complete monthly payment estimate.
LTV reflects how much you borrow compared to the home’s value. For conventional loans, when LTV rises above 80%, PMI is usually required, so these terms often come up together when borrowers decide how much to put down.
An ARM can be useful in certain scenarios, especially for borrowers who are comfortable with the possibility that the rate could adjust over time. It’s often compared with a fixed-rate mortgage when weighing short-term savings against longer-term payment certainty.
Common mortgage acronyms include APR, ARM, DTI, FHA, LTV, PITI, and PMI. These terms often appear in rate quotes, payment estimates, pre-approval discussions, and loan comparison documents.
FHA loans are insured by the Federal Housing Administration, which can make borrower qualification requirements more flexible. A conventional loan is not insured by the government, so borrowers often compare the two when weighing down payment options, credit flexibility, and overall loan fit.
For a conventional mortgage, PMI is usually required when the loan-to-value ratio is above 80%. Borrowers typically find out whether mortgage insurance applies when reviewing loan estimates, payment breakdowns, or lender guidance tied to the size of the down payment.
Mortgage acronyms commonly show up in lender conversations, rate quotes, monthly payment estimates, pre-approval discussions, underwriting, and loan comparison paperwork. Knowing the terms can make it easier to compare options and ask better questions.
These acronyms help explain how a loan may affect your rate, monthly payment, approval path, and down payment strategy. Understanding them can make lender offers easier to compare on more than just the advertised rate.
