30-year fixed mortgage rates: Pros and cons
There are two main advantages to a 30-year fixed mortgage: Your payments are lower, and your monthly payments are predictable.
A 30-year fixed-rate mortgage has relatively low monthly payments because you’re spreading your repayment out over a longer period of time than with, say, a 15-year mortgage. Your payments are predictable because, unlike with an adjustable-rate mortgage (ARM), your rate isn’t going to change from year to year. Most years, the only things that might affect your monthly payment are any changes to your homeowners insurance or property taxes.
The main disadvantage of 30-year fixed mortgage rates is the mortgage interest, both in the short and long term.
A 30-year fixed term comes with a higher rate than a shorter fixed term, and it’s higher than the intro rate to a 30-year ARM. The higher your rate, the higher your monthly payment. You’ll also pay much more in interest over the life of your loan due to both the higher rate and the longer term.
15-year fixed mortgage rates: Pros and cons
The pros and cons of 15-year fixed mortgage rates are basically swapped with those of the 30-year rates. Yes, your monthly payments will still be predictable, but another advantage is that shorter terms come with lower interest rates. Not to mention, you’ll pay off your mortgage 15 years sooner. So you’ll save potentially hundreds of thousands of dollars in interest over the course of your loan.
However, because you’re paying off the same amount in half the time, your monthly payments will be higher than if you choose a 30-year term.
Adjustable mortgage rates: Pros and cons
Adjustable-rate mortgages lock in your rate for a predetermined amount of time, then change it periodically. For example, with a 5/1 ARM, your rate stays the same for the first five years and then goes up or down once per year for the remaining 25 years.
The main advantage is that the introductory rate is usually lower than what you’ll get with a 30-year fixed rate, so your monthly payments will be lower. (Current average rates might not necessarily reflect this, though — in some cases, fixed rates are actually lower. Talk to your lender before deciding between a fixed or adjustable rate.)
With an ARM, you have no idea what mortgage rates will be like once the intro-rate period ends, so you risk your rate increasing later. This could ultimately end up costing more, and your monthly payments are unpredictable from year to year.
But if you plan to move before the intro-rate period is over, you could reap the benefits of a low rate without risking a rate increase down the road.
Is now a good time to buy a house?
First of all, now is a good time to buy a house compared to a couple of years ago. Home prices aren't spiking like they were during the height of the COVID-19 pandemic. So, if you want or need to buy a house soon, you should feel pretty good about the current housing market.
Mortgage rates have also dropped since this time last year.
The best time to buy is typically whenever it makes sense for your stage of life. Trying to time the real estate market can be as futile as timing the stock market — buy when it's the right time for you.
Today's mortgage rates: FAQs
Why do 30-year mortgage rates vary by the source reporting them?
According to Zillow, the national average 30-year mortgage rate is 6.31% right now. Why are Zillow's rates usually different than those reported by Freddie Mac (which reported 6.22% this week) and elsewhere? Each source compiles rates by different methods. Zillow obtains rates from its lender marketplace, and Freddie Mac pulls information from loan applications submitted to its underwriting system. However, mortgage rates vary by state and even ZIP code, by lender, loan type, and many other factors. That's why it's so important to shop with multiple mortgage lenders.
Are interest rates expected to go down?
According to February forecasts, the MBA expects the 30-year mortgage rate to be near 6.10% through 2026. Fannie Mae also predicts a 30-year rate near 6% through the end of the year.
Are mortgage rates dropping?
Mortgage rates dropped gradually from the end of May last year to the beginning of the Middle East war this year. The 30-year fixed rate topped out over 7% in January 2025, then bounced higher and lower for months. On May 29 2025, the 30-year rate was 6.89%, and began slowly moving down. After hitting three-year lows in February, rates began to bounce higher in March.
How do I get the lowest refinance rate?
In many ways, securing a low mortgage refinance rate is similar to when you bought your home. Try to improve your credit score and lower your debt-to-income ratio (DTI). Refinancing into a shorter term will also land you a lower rate, though your monthly mortgage payments will be higher.
