Why Did My Mortgage Payment Go Up? (Texas Homeowners, Read This)

A mortgage payment increase in Texas catches a lot of homeowners off guard – especially when they thought they had a fixed-rate loan. I get this question all the time from homeowners in Central Texas: “I thought my payment was fixed…why did it go up?”

Let’s break it down, because your mortgage payment isn’t always as “fixed” as people think.

Wait…Isn’t My Mortgage Supposed to Stay the Same?

Kind of. Your principal and interest — the actual loan portion — typically stay the same with a fixed-rate mortgage. But your total monthly payment can still change because of two things: property taxes and homeowners insurance. That’s usually what’s driving a mortgage payment increase, and most homeowners don’t realize it until they get the notice.

The Real Reason Your Payment Went Up

1. Property Taxes Increased

In Texas, property taxes are a major factor in your monthly payment. If you have a homestead exemption, your home’s taxable value can increase by up to 10% per year. That doesn’t mean your taxes only go up 10%. It means the value used to calculate your taxes can increase up to 10%. If tax rates or assessed values climb, your payment follows.

2. Homeowners Insurance Increased

Insurance premiums have been rising across Texas due to severe weather events like hail and storms, increased rebuilding costs, and higher claims activity in certain areas. If your insurance goes up, your monthly mortgage payment usually goes up with it.

Escrow: The Hidden Middleman

Most homeowners have an escrow account. Your lender collects money monthly for taxes and insurance, then pays those bills on your behalf. If those costs increase, your lender adjusts your payment to cover the difference. Sometimes that shows up as an escrow shortage, a one-time adjustment, or a permanently higher monthly payment. Reviewing your annual escrow statement is the best way to catch this before it surprises you.

“But My Payment Jumped A LOT…”

If your mortgage payment increase was significant, not just a small bump, a few things could be at play. A large jump in your property’s appraised value, a notable insurance premium increase, or an escrow shortage carried over from the previous year can all stack up fast. Sometimes it’s a combination of all three hitting at once.

This is exactly why reviewing your annual escrow statement matters. It tells you where the money is going and gives you a chance to catch problems before they compound into a bigger payment adjustment next year.

How This Connects to CAD (Important 👀)

Remember the County Appraisal District (CAD)?

The CAD determines your home’s taxable value. When your CAD value increases, your property taxes can increase, which directly drives a mortgage payment increase. This is why protesting your appraisal when the value seems off can actually put money back in your pocket every month.

What You Can Do About It

Review your property tax assessment every year
Consider protesting your taxes if the value seems high
Shop your homeowners insurance periodically
Make sure you’ve filed your homestead exemption
