Is Your Mortgage Payment Rising Without Warning?
If your monthly mortgage suddenly jumped by $100 or more, you’re not alone. Rising property taxes and insurance rates are sneaking into mortgage bills across the country—often hidden in annual escrow “audits” that most homeowners never see coming. This article will show you how to spot surprise charges, unmask the ‘escrow audit’ trick, and take real steps to stop overpaying—before next month’s statement arrives.
1. The Escrow Audit Surprise: Why Your Bill Might Suddenly Spike
Every year, mortgage companies review (“audit”) your escrow account to make sure there’s enough money to cover property taxes and homeowners insurance. If your taxes or premiums have gone up—sometimes by hundreds of dollars—your bill goes up too, often with barely any warning.
Homeowners in Charlotte, NC, saw average property values jump 40% after a reassessment, putting many at risk for major property tax increases.
Watch out: Even if you pay your mortgage on time, you can still be blindsided by these hidden hikes.
- Check your latest escrow statement (it comes every year—don’t toss it!)
- Look for new charges or big increases in tax or insurance columns
Review this with your last year’s statement. If amounts don’t match, ask your lender for a detailed breakdown. It’s your right to understand every increase.
2. Unfair Property Tax Assessments: How to Challenge Them
Property taxes aren’t set in stone. If your home’s value was overestimated or taxed unfairly, you have options.
In Florida, you can appeal your assessed property value at the county office or go to the county value adjustment board (Florida Department of Revenue).
Take action fast: There are deadlines to file appeals, so don’t delay once you spot an issue.
- Look up your home’s official assessed value on your local property appraiser’s website
- Compare with recent sale prices of similar homes
- If you believe the assessment is too high, file an appeal by the local deadline

States like California, Illinois, Maryland, Missouri, and Massachusetts have structured appeal processes—check your state’s process. In California, file an assessment appeal with your county board. Know your state’s rules and gather your evidence early.
3. Gather Your Evidence and Know Who Carries the Burden
If you’re challenging an assessment, the key is simple proof: What makes your home worth less than what the county says? Use recent sale prices, repair estimates, or photos of needed fixes.
Massachusetts tax appeals succeed when homeowners show “fair cash value” is lower than the assessed value—bring photos or recent sales to prove it (Mass.gov).
In California, if your home is your main residence, the assessor must prove their value is right—not you—but you still need backup if you’re contesting elsewhere.
- Print or screenshot recent sales of similar homes nearby
- Document any big repairs your home needs
Always file appeals in writing and track responses. For Illinois, a written appeal to the county board is required before going to higher levels (Illinois DOR).
4. Act Now—Don’t Let Extra Charges Pile Up
The faster you challenge errors or unfair increases, the better chance you have to stop extra hundreds from piling onto your mortgage—sometimes for years.
In Missouri and many other states, if the local office won’t fix a mistake, you can appeal up to a state commission.
Don’t let frustration lead to inaction: Mark your calendar for next year’s assessments and appeals. Ask your lender how often they audit your escrow. Request early notifications of increases.
Take the next step today: review your latest statement, check your assessment, and make an appeal if anything looks off.
Bottom Line: Take Control of Your Mortgage Now
Hidden charges can sneak into your mortgage payment through escrow audits, especially with rising taxes and insurance. By checking your escrow statements, investigating property tax assessments, and acting quickly, you can avoid hundreds in surprise bills. Don’t wait for your next statement shock—compare your assessed value, gather your proof, and file an appeal today if needed.
