One of the great things about buying a house with a fixed-rate mortgage is knowing exactly what your monthly housing payment will be for the next 15 or 30 years. No surprise rent hikes. No worrying about interest rates. Just the same predictable payment, month after month, while you steadily build equity in your home.
That's the idea, anyway.
Except your monthly mortgage payment isn't necessarily fixed at all. It's entirely possible for that payment to climb by 40% in just a few years, even if you've never refinanced, borrowed another dime, or made any major changes to your house.
How do I know? Because that's exactly what happened to us.
The Unwelcome Surprise at Our Five-Year Homeownership Anniversary
Last year, my husband, Michael, and I marked five years in our house in the most thrilling way imaginable: We pulled up our very first mortgage statement from 2020 and compared it with our latest one. We wanted to see how much of the loan we'd paid off.
That part was satisfying. The rest was not.
Somehow, the monthly payment on our fixed-rate mortgage that we'd never refinanced had gone up by roughly 40%.
Forty. Percent.
It didn't take long to find the culprit. You see, most mortgage payments have two parts. Principal and interest pay for the house itself, and on a fixed-rate loan, that amount stays the same for the life of the loan. Escrow is money your lender collects each month to pay your property taxes and homeowners insurance for you, and that amount can change every year.
The amount we were paying into escrow had nearly doubled in those five years, going from around $1,000 a month to more than $1,900 a month. Some of the increase came from property taxes, but most of it came from something we'd barely thought about since closing: homeowners insurance.
We hadn't renovated. We hadn't filed a claim. It was the same house we'd bought in 2020. It had simply become a much more expensive house to insure, and as we soon learned, we had plenty of company.
The Part of Your Mortgage That Was Never Fixed
Here's what many homeowners don't realize until it happens to them. Under federal rules, your mortgage servicer must review your escrow account once a year, comparing what it collected from you with what it actually paid out for taxes and insurance. Then it resets your monthly payment for the year ahead.
If your bills went up, that annual review can hit you twice. First, your monthly escrow payment rises to cover the new, higher costs going forward. Second, if last year's bills came in higher than the servicer expected, your account may have run short, and the servicer can ask you to make up the difference, often by spreading the shortfall across your next 12 payments. Servicers are also allowed to keep a cushion of up to two months' worth of escrow payments, and that cushion grows right along with your bills.
That's how a "fixed" mortgage payment can jump by hundreds of dollars in a single year.
When people talk about housing affordability, the conversation usually revolves around home prices and mortgage rates. Homeowners who locked in a low rate years ago often assume they've insulated themselves from at least one major household expense. But every extra dollar flowing into escrow is a dollar that can't go toward retirement savings, college funds, or a little breathing room in the family budget. And unlike a pricey streaming subscription, homeowners insurance isn't something you can just cancel. Mortgage lenders typically require it, and going without adequate coverage could expose you to a financially devastating loss.
And this can all happen without you doing anything "wrong." You don't have to refinance, renovate, or file a claim. You just have to own a home while the cost of taxing and insuring it goes up... which is exactly what's happening throughout most of the United States.
Why Insurance Is Doing Most of the Damage
While rising property taxes have historically been the bane of many a homeowner, in much of the country, insurance has suddenly become the bigger bully.
According to a new Bloomberg Intelligence analysis, the average homeowners insurance premium now exceeds the average property tax bill in roughly two-thirds of U.S. counties.
And it isn't just a handful of hurricane-prone coastal communities dealing with the problem. Bloomberg found that average premiums have risen 45% over the past decade after adjusting for inflation, with some of the steepest increases in the Midwest and Mountain West, where hail and severe winter weather have driven up losses. In Nebraska, premiums have climbed an inflation-adjusted 79%.
A Consumer Federation of America report found that the typical homeowner's annual premium rose 24% between December 2021 and August 2024, from $2,655 to $3,303. That's an extra $648 a year, nearly double the rate of inflation over the same period. If you pay through escrow, that works out to about $54 more every month, before any shortfall catch-up. Premiums increased in 95% of U.S. ZIP codes, and in about a third of them, they climbed more than 30%.
No wonder 71% of homeowners told the Pew Research Center this spring that their insurance costs had gone up over the past few years, including 42% who said they'd gone up a lot.
Why is this happening? Your insurer doesn't care what you paid for your house. It cares what it would cost to rebuild it. According to a U.S. Treasury Department report, replacement costs for property and casualty insurance losses rose an average of 45% between 2020 and 2023. Meanwhile, hurricanes, wildfires, hailstorms, and floods are producing bigger and more frequent losses, and those costs don't stay neatly confined to the places where disasters strike. Insurers also buy their own insurance, called reinsurance, to protect against catastrophes, and when that coverage gets more expensive, the cost works its way into everyone's premiums.
So you might have the same roof, the same floor plan, and the same perfectly ordinary house you bought five years ago. The cost of insuring it can still look completely different.
How to Get Your "Fixed" Payment Back Under Control
You can't make escrow go away. But you have more control over what goes into it than you might think.
1. Actually read your escrow analysis
That annual escrow statement is easy to toss, but it tells you exactly why your payment is changing. Look at whether the increase came from taxes, insurance, or a shortage. If there's a shortage, ask your servicer whether you can pay it in a lump sum instead of spreading it across the next year's payments. Federal rules give servicers some flexibility here, and paying it off can keep your monthly bill lower.
And if you switch insurers or win a lower tax bill, make sure your servicer has the new information and recalculates your escrow. Otherwise, you could do all the work of lowering your costs and still be wondering why your mortgage bill hasn't budged.
2. Don't automatically renew your insurance policy
After discovering how much our payment had increased, Michael and I did what any sensible homeowners would do: We complained about it to a friend. Fortunately, this friend happens to be a Realtor, and instead of joining us in our outrage, she offered some useful advice. Shop around.
So we did. And, wouldn't you know it, we found comparable coverage at a substantially lower price. It didn't magically restore our 2020 mortgage payment, but it made a meaningful difference. I just wish we'd done it sooner.
Insurance companies don't all price risk the same way. One might consider your home a relatively expensive risk, while another might offer comparable protection for considerably less. Get quotes from several companies, and consider working with an independent insurance agent who can compare multiple insurers for you. Just make sure you're comparing more than the price. A cheaper policy isn't much of a bargain if it offers substantially less protection.
3. Take a closer look at what your policy actually covers
When was the last time you read your homeowners insurance policy? Not the bill, the actual coverage. Look at your dwelling coverage, how your policy handles replacement costs, and any exclusions or limitations for things like wind, hail, or water damage. Make sure the amount of insurance you carry reflects what it would cost to rebuild your home, not simply its market value. And check whether your policy has a separate wind or hail deductible calculated as a percentage of your home's insured value rather than a flat dollar amount. That can make for a very unpleasant surprise when you file a claim.
4. Ask about discounts
Insurers may offer discounts for bundling your home and auto policies, installing protective devices, or making improvements that reduce the likelihood of damage, such as impact-resistant roofing in hail- or storm-prone areas. Just don't spend thousands of dollars on upgrades without first finding out whether they'll actually save you money.
5. Be careful about raising your deductible
A higher deductible is one common way to lower a premium, and if you have a healthy emergency fund, it might be a reasonable trade-off. But remember what you're doing: You're taking on more financial risk in exchange for a lower annual bill. Saving a few hundred dollars a year may not be worth exposing yourself to thousands of dollars in additional costs after a storm.
6. Challenge your property tax assessment
Insurance isn't the only thing flowing through escrow. If your property tax bill has climbed, check your assessment notice. Local governments generally let homeowners appeal an assessment they believe is too high, though deadlines and procedures vary by location, and the windows can be short. Look for errors in your property record, such as the wrong square footage or number of bathrooms, and compare your assessment with similar homes nearby. Also make sure you're receiving every exemption you qualify for, such as a homestead exemption.
Few people bother. Pete Sepp, president of the National Taxpayers Union, has estimated that only 3% to 5% of homeowners file an appeal, but that 30% to 50% of those who do win some kind of reduction. Keep in mind that an appeal can lower your home's assessed value, not your local tax rate.
What "Fixed" Really Means
I'm still glad Michael and I bought our house when we did. I'm glad we locked in a fixed interest rate. And I'm especially glad we spent that fifth homeownership anniversary marveling at how much progress we'd made on our mortgage, even if our little celebration did come with a rather rude financial awakening.
But the experience changed how I think about our housing costs. A fixed-rate mortgage isn't a promise that your house will cost the same amount every month for the next 30 years. It's a promise that one part of your housing payment will stay the same.
The rest? Well, apparently that's still up for negotiation.
You can't control the weather, the cost of construction materials, or your county's tax rate. But you can compare policies. You can ask questions. You can check your assessment and make sure you're paying for the right coverage at a competitive price.
And if you haven't looked at your escrow statement or your homeowners insurance policy in a few years, take it from someone who learned this lesson the expensive way: It might be worth a few hours of your time.
