Fixed rate does not always mean fixed total payment
Many monthly mortgage payments combine principal and interest with an escrow amount for property taxes and homeowners insurance. The principal-and-interest portion may stay the same while the escrow portion changes.
The most common causes
- Local property taxes were reassessed or increased.
- Your homeowners insurance premium renewed at a higher amount.
- Your prior escrow collections were not enough to cover actual bills.
- A temporary escrow-shortage repayment was added.
- Another payment component or servicing fee changed.
How to check the explanation
Compare the previous and new annual tax and insurance figures. Divide each annual change by 12, then add the monthly shortage repayment. That estimate should be close to the total monthly payment change if escrow explains it.
If a meaningful difference remains, check whether principal and interest, mortgage insurance, fees, or another line item changed too.
Look beyond escrow if the math still does not match
Review mortgage insurance, optional products, servicing fees, an adjustable feature, a loan modification, or a payment-plan change. Your periodic statement should help separate principal, interest, escrow, and fees.
