The most common reason: your property taxes or homeowners insurance increased
If you have an escrow account — a holding account your lender manages for taxes and insurance — your payment rises when either of those costs goes up. Your lender collects a portion of taxes and insurance each month alongside your principal and interest, then pays the bills when they come due. When the tax assessor raises your home's value or your insurance company increases your premium, your monthly escrow payment increases to match.
This is the single most common reason payments jump. Property tax increases happen annually in most places, and insurance premiums often rise yearly as well. If you received a notice from your county assessor or your insurance company, that is almost certainly why your payment changed.
Your lender is required to send you an escrow analysis statement when they recalculate your payment. This document shows the old and new amounts for taxes, insurance, and your total monthly payment. Check the dates on the statement — it will tell you when the change takes effect.
Key Takeaways
- Property tax increases and homeowners insurance premium increases are passed through your escrow account to your monthly payment, and both happen most years.
- Your lender must send you an escrow analysis statement explaining the old and new payment amounts before the change takes effect.
- If you have an adjustable-rate mortgage (ARM), your interest rate may have reset to a higher rate on your anniversary date, raising the principal-and-interest portion of your payment.
- You can request a manual property tax assessment in some counties to challenge a recent increase, though the process and timeline vary by location.
- Switching from an escrow account to paying taxes and insurance yourself is possible in some cases, but requires meeting your lender's equity requirements.
How adjustable-rate mortgages reset and change your payment
If you have an ARM (adjustable-rate mortgage), your interest rate is fixed for an initial period — commonly 3, 5, 7, or 10 years — then adjusts annually or semi-annually after that. When the rate resets, your monthly payment for principal and interest changes, sometimes significantly.
The new rate is tied to a market index (such as the Secured Overnight Financing Rate, or SOFR) plus a margin your lender set at closing. When the index rises, your rate rises. Your loan documents spell out the exact adjustment date and any caps on how much the rate can increase per adjustment period or over the life of the loan.
If you are past your initial fixed period and your payment jumped, check your loan documents or contact your lender to confirm your rate reset date. ARMs are less common now than they were before 2008, but they still exist, especially in refinances or portfolio loans.
Property tax reassessment and how to respond
Most counties reassess property values annually, and some do it every few years. When your home's assessed value increases, your property tax bill increases proportionally, and that increase flows into your escrow payment. A reassessment can happen because comparable homes in your area sold for more, because you made major improvements, or simply because the assessor updated their valuation model.
You have the right to challenge a reassessment in most jurisdictions. The process usually involves filing a formal appeal with your county assessor or a board of equalization within a set window — often 30 to 60 days after you receive the notice. You will need to provide evidence: recent appraisals, photos of damage or deferred maintenance, or sales data for comparable homes that sold for less.
Contact your county assessor's office directly to learn the deadline and what documents they require. Some counties allow informal meetings before you file a formal appeal, which can resolve disputes without paperwork. If you succeed in lowering the assessed value, your property tax bill drops, and your escrow payment adjusts downward on the next analysis.
Insurance premium increases and shopping for a new policy
Homeowners insurance premiums rise for many reasons: increased claims in your area, inflation in repair and replacement costs, changes to your home's risk profile (roof age, prior claims on your record), or simply the insurance company's decision to raise rates across a region. Your lender receives the new premium from your insurance company and passes the increase to you through escrow.
You are not locked into your current insurance company. You can shop for a new policy with a different insurer at any time, and if you find a lower rate, you can switch. Provide your new insurer with your lender's name and loan number so they can issue the policy in the correct format. Your lender must accept a policy from any insurer that meets their minimum coverage requirements.
When you switch insurers, notify your old company to cancel, and make sure the new policy's effective date overlaps with the cancellation date so there is no gap. Your lender will update their escrow account once they receive the new insurance declaration page, and your payment will adjust on the next analysis.
Escrow account shortfalls and how they affect your payment
An escrow shortage occurs when the amount you have been paying into escrow each month is not enough to cover the actual taxes and insurance bills. This can happen if taxes or insurance rose more than your lender predicted when they last calculated your payment, or if a large bill came due unexpectedly.
When a shortage is discovered during the annual escrow analysis, your lender has options: they can raise your monthly payment to cover the shortage over the next 12 months, or they can allow you to pay the shortage in a lump sum. Some lenders do both — they raise the monthly payment and ask you to pay part of the shortage upfront. Your escrow analysis statement will show which option applies to you.
If you cannot pay a lump-sum shortage, contact your lender to discuss a payment plan. Some lenders will spread the shortage over 24 months instead of 12, lowering the monthly increase. This is negotiable, and it costs nothing to ask.
Loan modifications and payment recalculations
If you recently modified your loan — extended the term, refinanced, or changed from an ARM to a fixed rate — your payment recalculation may have increased the monthly amount even if your interest rate stayed the same or dropped. This usually happens when you extend the loan term: spreading the same principal over more years lowers the monthly payment, but if you also rolled closing costs into the loan balance, the total amount owed increased, which can offset the benefit of a longer term.
Review the closing disclosure from your modification to see the new loan amount, term, and interest rate. If the payment increase does not match what you expected, ask your lender to walk you through the calculation. Errors in loan modifications are rare, but they do happen, and catching them early is important.
Frequently Asked Questions
Can I remove escrow from my mortgage and pay taxes and insurance myself?
Some lenders allow this if you have enough equity in the home — typically 20 percent or more. Contact your lender to ask about their policy. If you remove escrow, you are responsible for paying property taxes and insurance on time yourself; missing either payment can result in a tax lien or a lapse in coverage, both of which can trigger a loan default.
What if my escrow payment increased but I did not receive a statement?
Federal law requires lenders to send an escrow analysis statement before the payment changes. If your payment increased without notice, contact your lender immediately and ask for the statement. If they cannot produce one, the increase may not be valid, and you may be owed a refund.
How long does it take for a property tax appeal to be decided?
Timelines vary by county. Informal appeals can be resolved in weeks; formal appeals often take several months to a year. Contact your county assessor's office for their specific timeline. If you win the appeal, the new assessed value takes effect on the next tax bill, which may not arrive for several months.
If I switch insurance companies, will my lender accept the new policy?
Yes, as long as the new policy meets your lender's minimum coverage requirements — usually dwelling coverage equal to the loan amount or the home's replacement cost, whichever is higher. Provide your lender with the new policy's declaration page, and they will update their records. Your escrow payment will adjust once they receive the new premium information.
Does my payment increase mean my interest rate went up?
Not necessarily. If you have a fixed-rate mortgage and your payment increased, it is almost always because property taxes or insurance went up, not because your interest rate changed. Only ARMs have interest rates that reset. Check your escrow analysis statement to see the breakdown of taxes, insurance, and principal-and-interest.
