A 30-year fixed mortgage was supposed to be the great American hedge against housing volatility. Lock in a rate, lock in a payment, sleep at night. That logic is breaking down in real time. According to a CNBC report on new Cotality data, roughly 65% of escrow accounts in the United States are projected to be short this year. The average shortfall is $2,157. Spread over 12 months, that is an additional $179.75 a month landing on top of a payment most homeowners thought was nailed down for the life of the loan. For households that planned their budget around a steady principal-and-interest figure, the escrow recalculation letter is becoming one of the most disruptive pieces of mail of the year.
The core problem is structural. About 80% of mortgage borrowers in the United States have an escrow account, according to Lereta, which provides real estate tax and flood data to mortgage servicers. That account holds the money the lender uses to pay property taxes, homeowners insurance, and, if required, mortgage insurance. The escrow is reviewed once a year. The servicer projects the next 12 months of tax and insurance bills, compares the projection to what is already in the account, and either issues a refund or assesses a shortage. The shortage is then either paid in a single lump sum or amortized over the next 12 monthly payments. When tax and insurance bills are rising faster than the projections assumed, the shortages compound year after year. That is exactly the regime we are now living in.
Escrow Costs Are Up 45% Since 2019
The numbers are not subtle. Cotality, the property data and analytics firm formerly known as CoreLogic, reports that the average amount American homeowners pay into escrow each year has risen approximately 45% since 2019. That is well above the cumulative consumer price index inflation over roughly the same window, which was about 30% from May 2019 to April 2025 based on Bureau of Labor Statistics data. In other words, the escrow component of a mortgage payment has outpaced general inflation by roughly 15 percentage points over six years.
The state-level numbers are more dramatic than the national average. In Florida, escrow costs have jumped 70%. In Colorado, they have jumped 77%. Those two states are the canary in the coal mine for a national trend driven by two intersecting forces: insurance market dislocation from severe weather and natural disasters, and property tax inflation tied to elevated home values. Florida is the obvious case study for the first force. Colorado, with its wildfire risk and hot housing market, captures both forces simultaneously. The states where escrow shortages are smaller tend to be those with capped property tax growth and lower insurance volatility, but no state is immune.
The mechanics of the shortage are worth unpacking because most homeowners do not see it coming. When you closed on your house, the servicer estimated what your taxes and insurance would be over the next 12 months. They added a small cushion, typically up to two months of payments, as a buffer required by federal regulation. They divided the total by 12 and added it to your monthly principal and interest. A year later, when your insurance renewal came in 15% higher and your property assessment delivered a 9% tax increase, the actual outflow from your escrow account exceeded what the servicer projected. The cushion got eaten. You now owe the difference, plus a new, higher monthly contribution to fund the next 12 months at the new tax and insurance rates. Your monthly payment can jump 10% to 15% in a single recalculation without anyone touching your interest rate.
The Insurance Story Is the Bigger Driver
For most of the last 50 years, property taxes were the dominant variable in escrow growth. That is starting to flip. The average annual cost of homeowners insurance is projected to reach $3,057 by the end of 2026, up 4% from $2,948 in 2025, according to Insurify. That is a single-year increase, and it sits on top of a much larger multi-year trend. The average homeowners insurance premium has risen 46% since 2021. Selma Hepp, chief economist at Cotality, told CNBC that in some markets “insurance has grown much faster and is outpacing the overall amount that you have to put in escrow for property taxes.”
That insurance number is doing several things at once. It is repricing physical risk in coastal and wildfire-exposed markets where carriers are reducing capacity. It is repricing reinsurance costs, which have risen sharply as global catastrophe losses pile up. It is repricing labor and materials costs for rebuilding, which inflation pushed up sharply during the post-COVID period and which have not come back down. And it is reflecting carrier balance sheet stress from a sequence of bad years in homeowners lines, which has led to non-renewals, surcharges, and in some cases full market exits from states like Florida and California. The net effect on the consumer is that the insurance line in the escrow recalculation letter is now the variable most likely to surprise on the upside.
Property taxes, while still a major escrow input, are showing a softer trajectory in much of the country. The U.S. average yearly property tax paid by homeowners reached $3,018 in 2024, up 27.4% from 2019, according to Cotality. Over that same period, home prices jumped 51.6%. The gap between price appreciation and tax growth reflects the various caps and assessment lags built into state and local property tax systems. Those caps will catch up over time as assessments reset, but for now, insurance is the more aggressive contributor to escrow shortfalls. Homeowners in areas with frequent reassessments or no assessment cap, including parts of Texas, Colorado, and the Mountain West, are seeing both lines move against them simultaneously.
What Servicers Will Offer and What You Should Actually Do
When the escrow analysis letter arrives, the servicer will typically present two options. Option one is to pay the shortage in a lump sum. Option two is to spread it across the next 12 monthly payments. Stephen Kates, a certified financial planner and analyst at Bankrate, told CNBC that the lump sum is usually the better move if the household has the cash. “If you have enough in your emergency fund to cover the shortfall all at once, that will be the simplest way to put it behind you,” he said. He added a sharper point about the math of monthly amortization. “Paying over time can leave you layering shortage payments on top of the higher ongoing monthly payments created by the yearly updated escrow calculation.”
That is the trap. The shortage from this year is being paid down at the same time the next year’s higher run rate is being collected. If the trend continues, the next escrow analysis will find another shortage, and another 12 months of payments stacked on top. A household that resolves this year’s $2,157 shortfall with a single check and then adjusts to the new higher monthly contribution will break the spiral. A household that takes the 12-month plan will face compounding pressure when the next analysis arrives. For households with adequate emergency savings, paying the shortage upfront is almost always the right call.
There are also two upstream interventions worth considering, neither of which most homeowners exercise. The first is shopping the insurance policy. Many homeowners have been with the same carrier for years and have absorbed renewal increases without comparison shopping. Carriers that exited certain states have been replaced by new entrants, often at materially different price points. Bundling auto and homeowners coverage, raising deductibles, and reviewing coverage limits against actual replacement cost can yield meaningful savings, especially in markets where premiums have run up the fastest. The second intervention is appealing the property tax assessment. This is more useful than most homeowners realize, but it requires evidence. Kates was specific on this point: “Do not appeal just because the bill feels expensive, and do not do it automatically every assessment cycle.” Appeals work when the homeowner can show comparable sales or condition issues that justify a lower assessed value. They do not work as a general protest.
Senior exemptions, veteran exemptions, and homestead caps are also widely available in many states and meaningfully under-utilized. Local government finance offices will usually publish a list of available exemptions, but the homeowner has to apply. Anyone over age 65, anyone with a service-connected disability, and anyone who has owned and occupied their home for a long time should check what their county and state offer.
The Affordability Implication
Stepping back from the household-level mechanics, the escrow trend is part of a broader affordability story that is reshaping the U.S. housing market. The headline mortgage rate gets all the attention, but the all-in monthly cost of homeownership is now meaningfully higher than the principal-and-interest line implies, and the gap is widening. For a household with a $300,000 mortgage at a 6.5% rate, the principal and interest is roughly $1,896 a month. Layered on top is roughly $250 in homeowners insurance and roughly $250 in property taxes, with mortgage insurance for many lower-down-payment borrowers. The escrow side of the payment is approaching 25% to 30% of the total, and it is the side that is moving fastest.
That dynamic has consequences for the broader housing market that show up in the data underlying the housing market outlook. It compresses affordability without requiring rates to rise. It pushes more households into a renting decision at the margin. It increases delinquency risk for borrowers who stretched at origination. And it amplifies the regional dispersion of the housing market, with states like Florida and Colorado seeing meaningfully different cost trajectories than states with capped tax growth and stable insurance markets.
The personal finance takeaway is to treat the escrow recalculation as a recurring household decision, not a one-time event. Build the expected escrow growth into the household budget. Keep enough liquidity to pay shortages in lump sums rather than amortize them. Shop the insurance every two years. Appeal property tax assessments when there is real evidence. And accept that the fixed-rate mortgage hedges interest rate risk, not the full cost of homeownership. For an economy where so much household wealth and so much consumer confidence is tied to the home, that distinction is becoming more important every year. The credit and balance sheet pressures showing up across the broader consumer data all start with payments like these.
Frequently Asked Questions
What is a mortgage escrow account?
An escrow account is a holding account managed by your mortgage servicer that collects monthly contributions from you and pays your property taxes, homeowners insurance, and, if required, mortgage insurance on your behalf. About 80% of U.S. mortgage borrowers have an escrow account. The servicer reviews the account annually, projects the next year’s tax and insurance bills, and adjusts the monthly contribution accordingly. Borrowers who do not have an escrow account pay taxes and insurance directly.
Why is my fixed-rate mortgage payment going up?
The interest portion of your payment is fixed for the life of the loan. The escrow portion is not. When your property tax bill or homeowners insurance premium increases, the servicer raises your monthly escrow contribution to cover the higher costs and to repay any shortage that built up during the previous year. The result is a higher total monthly payment even though your rate has not changed.
How big is the average escrow shortage in 2026?
The average projected shortage in 2026 is $2,157, according to Cotality. Roughly 65% of escrow accounts are expected to be short. Spread across 12 monthly payments, the average shortage adds about $179.75 to the monthly payment. In states with the largest insurance and tax increases, including Florida and Colorado, shortages have been meaningfully larger.
Should I pay an escrow shortage upfront or over 12 months?
If your emergency fund can absorb the lump sum, paying it upfront is generally better. Spreading the shortage over 12 months stacks the repayment on top of the new, higher ongoing monthly contribution. If the underlying trend continues, the next year’s escrow analysis will likely find another shortage on top of the one still being paid down, creating a compounding payment increase. The lump sum stops that spiral.
Can I lower my homeowners insurance premium?
Yes, often meaningfully. Strategies include shopping multiple carriers, especially if you have been with the same one for several years, bundling auto and home coverage, raising your deductible, reviewing coverage limits to make sure they match actual replacement cost rather than market value, and asking for discounts tied to home safety features like alarm systems, impact windows, or roof age.
Can I appeal my property tax assessment?
In most jurisdictions, yes. Appeals are most successful when you can present comparable sales, an independent appraisal, or evidence of condition issues that justify a lower assessed value. A successful appeal can reduce your escrow contribution materially. Filing a generic protest without evidence rarely works and can be a waste of time. Check with your local assessor’s office for the appeal process and deadlines.
Why have homeowners insurance costs risen so much?
The average homeowners insurance premium has risen 46% since 2021, according to Insurify. The drivers include severe weather and natural disaster losses, rising reinsurance costs, higher rebuild costs from materials and labor inflation, and carrier balance sheet stress that has led to non-renewals and market exits in some states. The 2026 national average is projected to reach $3,057.
