What is a mortgage?

Most people don’t have the cash to simply buy a house. Instead, they use a mortgage, which is a loan to buy a home. After making a down payment of anywhere from 3% to 25%, they get a mortgage to cover the remaining costs of purchasing the home.

mortgage is set up so you pay off the loan over a specified period called the term. The most popular term is 30 years. Each payment includes a combination of principal and interest, as well as property taxes, and, if needed, mortgage insurance. (Homeowners insurance may be included, or the homeowner may pay the insurer directly.) Principal is the original amount of money you borrowed while interest is what you’re being charged to borrow the money.

How do mortgage rates work?

The mortgage rate a lender offers you is determined by a mix of factors that are specific to you and larger forces that are beyond your control.

Lenders will have a base rate that takes the big stuff into account and gives them some profit. They adjust that base rate up or down for individual borrowers depending on perceived risk. If you seem like a safe bet to a lender, you’re more likely to be offered a lower interest rate.

Factors you can change:

  • Your credit score. Mortgage lenders use credit scores to evaluate risk. Higher scores are seen as safer. In other words, the lender is more confident that you’ll successfully make your mortgage payments.

  • Your down payment. Paying a larger percentage of the home’s price upfront reduces the amount you’re borrowing and makes you seem less risky to lenders. You can calculate your loan-to-value ratio to check this out. A LTV of 80% or more is considered high.

  • Your loan type. The kind of loan you’re applying for can influence the mortgage rate you’re offered. For example, jumbo loans tend to have higher interest rates.

  • How you’re using the home. Mortgages for primary residences — a place you’re actually going to live — generally get lower interest rates than home loans for vacation properties, second homes or investment properties.

Forces you can’t control:

  • The U.S. economy. Sure, this means Wall Street, but non-market forces (for example, elections) can also influence mortgage rates. Changes in inflation and unemployment rates tend to put pressure on interest rates.

  • The global economy. What’s happening around the world will influence U.S. markets. Global political worries can move mortgage rates lower. Good news may push rates higher.

  • The Federal Reserve. The nation’s central bank attempts to guide the economy with the twin goals of encouraging job growth while keeping inflation under control. Decisions made by the Federal Open Market Committee to raise or cut short-term interest rates can sometimes cause lenders to raise or cut mortgage rates.

How (and why) to compare mortgage rates

Mortgage rates like the ones you see on this page are sample rates. In this case, they’re the averages of rates from multiple lenders, which are provided to NerdWallet by Zillow. They let you know about where mortgage rates stand today, but they might not reflect the rate you’ll be offered.

When you look at an individual lender’s website and see mortgage rates, those are also sample rates. To generate those rates, the lender will use a bunch of assumptions about their “sample” borrower, including credit score, location and down payment amount. Sample rates also sometimes include discount points, which are optional fees borrowers can pay to lower the interest rate. Including discount points will make a lender’s rates appear lower.

To see more personalized rates, you’ll need to provide some information about you and about the home you want to buy. For example, at the top of this page, you can enter your ZIP code to start comparing rates. On the next page, you can adjust your approximate credit score, the amount you’re looking to spend, your down payment amount and the loan term to see rate quotes that better reflect your individual situation.

Whether you’re looking at sample rates on lenders’ websites or comparing personalized rates here, you’ll notice that interest rates vary. This is one reason why it’s important to shop around when you’re looking for a mortgage lender. Fractions of a percentage might not seem like they’d make a big difference, but you aren’t just shaving a few bucks off your monthly mortgage payment, you’re also lowering the total amount of interest you’ll pay over the life of the loan.

It’s a good idea to apply for mortgage preapproval from at least three lenders. With a preapproval, the lenders verify some of the details of your finances, so both the rates offered and the amount you’re able to borrow will be real numbers. Each lender will provide you with a Loan Estimate. These standardized forms make it easy to compare interest rates as well as lender fees.

When you’re comparing rates, you’ll usually see two numbers — the interest rate and the APR. The APR, or annual percentage rate, is usually the higher of the two because it takes into account both the interest rate and the other costs associated with the loan (like those lender fees). Because of this, APR is usually considered a more accurate measure of the cost of borrowing.


The interest rate is the percentage that the lender charges for borrowing the money. The APR, or annual percentage rate, is supposed to reflect a more accurate cost of borrowing. The APR calculation includes fees and discount points, along with the interest rate.

APR is a tool used to compare loan offers, even if they have different interest rates, fees and discount points. APR takes ongoing costs like mortgage insurance into account, which is why it’s usually higher than the interest rate.

Discount points are basically prepaid interest that reduces the interest rate on your mortgage. One discount point costs 1% of the loan amount, and will usually drop the interest rate by 0.25%.

Buying points is optional. Be on the lookout for them, as a lender may add points to a loan offer to make their interest rate seem more competitive. It’s up to you to decide if paying for points as part of your closing costs is worth it.

The impact of a 0.25% change in the interest rate depends on the loan amount, the term and the interest rates. To illustrate, let’s look at a $250,000 mortgage with a 30-year term, and the differences in payment between an interest rate of 4% and a rate of 4.25%.

At 4%, the monthly principal and interest cost $1,193.54. At 4.25%, the monthly principal and interest cost $1,229.85. So, for a $250,000 mortgage with a 30-year term, cutting the interest rate from 4.25% to 4% saves $36.31 a month and $436 a year.

Mortgage rates not only vary from day to day, but hour to hour. In order to know what rate you’ll pay, you need the rate you’re offered to stop changing. A mortgage rate lock is the lender’s guarantee that you’ll pay the agreed-upon interest rate if you close by a certain date. Your locked rate won’t change, no matter what happens to interest rates in the meantime.

It’s a good idea to lock the rate when you’re approved for a mortgage with an interest rate that you’re comfortable with. Consult with your loan officer on the timing of the rate lock. Ideally, your rate lock would extend a few days after the expected closing date, so you’ll get the agreed-upon rate even if the closing is delayed a few days.
