You open your mortgage statement and suddenly notice something you weren’t expecting:

Your monthly payment went up.

But you have a fixed-rate mortgage. Isn’t the payment supposed to stay the same?

Not necessarily.

Even when the principal and interest portion of your mortgage stays the same, your total monthly mortgage payment can change because of property taxes, homeowners insurance, and your escrow account.

For Savannah homeowners, understanding why this happens can make that unexpected mortgage statement a lot less confusing.

First, What Is Included in Your Mortgage Payment?

Depending on your loan, your monthly mortgage payment may include several different expenses:

  • Principal
  • Interest
  • Property taxes
  • Homeowners insurance
  • Mortgage insurance, when applicable

If you have an escrow account, your lender collects money throughout the year to cover certain expenses, typically including property taxes and homeowners insurance.

Instead of paying those bills separately when they're due, you're essentially contributing toward them each month through your mortgage payment.

The catch?

Property taxes and homeowners insurance premiums can change.

And when they do, your mortgage payment may change too.

Reason #1: Your Property Taxes Changed

One of the first things to review when your mortgage payment increases is your property tax bill or assessment.

Property taxes aren't permanently fixed at the amount you paid when you purchased your home.

Changes in assessed value and other factors affecting your tax bill can mean your lender needs to collect more through escrow.

If you receive a new property tax assessment, don't automatically file it away.

Take a look at the value assigned to your property and make sure the information about your home appears accurate.

If you believe your home's assessed value is incorrect, there may be an opportunity to appeal within the applicable deadline.

For Savannah and Chatham County homeowners, keeping an eye on your property's assessed value is important not only when you're thinking about selling but also while you own the home.

Reason #2: Your Homeowners Insurance Premium Increased

Your homeowners insurance is another major piece of the escrow puzzle.

Insurance premiums don't necessarily stay the same from year to year.

If your annual premium increases, your lender may need to collect more money each month to make sure there will be enough in your escrow account when the insurance bill comes due.

If you notice a significant increase, review your policy and talk with your insurance professional about your coverage and available options.

It may also be worth comparing quotes periodically.

The goal isn't necessarily to find the cheapest possible policy. It's to understand what you're paying for and make sure your coverage and cost still make sense for your situation.

Reason #3: You Have an Escrow Shortage

This is the part that catches a lot of homeowners by surprise.

Your lender periodically reviews your escrow account through an escrow analysis.

They're essentially asking:

Did we collect enough money to cover the property taxes and insurance bills we're responsible for paying?

If those expenses increased and your lender didn't collect enough during the previous year, you could have an escrow shortage.

Your lender may then adjust the amount collected each month for the coming year. Depending on your lender and situation, you may also be given options for addressing the shortage.

That's why your payment can increase even when your mortgage interest rate hasn't changed.

What Should You Do If Your Mortgage Payment Goes Up?

Don't panic, but don't ignore the notice either.

Start by reviewing exactly what changed.

1. Read Your Escrow Analysis

Your annual escrow statement can show:

  • How much money went into your escrow account
  • What your lender paid from the account
  • Your projected taxes and insurance
  • Whether you have an escrow shortage or surplus
  • Your new monthly escrow requirement

If the paperwork feels like it was written for someone with a minor in mortgage hieroglyphics, you're definitely not the only one.

Focus first on identifying which expense increased.

2. Review Your Property Tax Information

Check the assessed value and property information used to calculate your taxes.

If something doesn't look right, investigate it rather than assuming the number is automatically correct.

Property tax assessments may have specific appeal windows, so timing can matter.

3. Review Your Homeowners Insurance

Look at your current premium and compare it with the previous year.

If the cost increased significantly, contact your insurance professional and ask why.

You can also ask whether there are coverage changes, discounts, deductible options, or other factors worth reviewing.

4. Understand Your Escrow Shortage Options

If your lender identifies a shortage, carefully read the options provided.

The source material notes that homeowners may be given the choice to address a shortage upfront or have it incorporated into payments over the following year, depending on the lender and circumstances.

Before choosing an option, make sure you understand how it would affect your monthly budget.

Why Savannah Homeowners Should Pay Attention to Home Value

Your home's value isn't something you only need to think about when you're ready to sell.

Knowing what's happening with your property can also provide useful context when reviewing:

Property taxes. Insurance. Equity.

For example, understanding your home's current market value can help you compare what's happening in the Savannah real estate market with the value appearing on your property assessment.

Keep in mind that market value and assessed value are not necessarily the same thing, so a real estate market analysis is not a substitute for your official tax assessment.

But having current local real estate information can give you a better starting point for understanding the bigger picture.

Your Mortgage Payment Changed. Now What?

An increased mortgage payment doesn't automatically mean something is wrong.

It may simply mean that the expenses being paid through your escrow account have changed.

The important thing is knowing why.

Review your escrow analysis. Check your property tax information. Look at your homeowners insurance premium. And don't be afraid to ask questions when something doesn't make sense.

Frequently Asked Questions

Why did my mortgage payment increase if I have a fixed interest rate?

A fixed-rate mortgage generally keeps your principal and interest payment consistent, but the total amount you pay each month can still change if expenses collected through escrow, such as property taxes or homeowners insurance, increase.

What is an escrow analysis?

An escrow analysis is your lender's review of the money being collected and paid through your escrow account. The lender estimates upcoming expenses and determines whether your monthly escrow contribution needs to change.

Can homeowners insurance make my mortgage payment go up?

Yes. If homeowners insurance is paid through your escrow account and your insurance premium increases, your lender may increase the amount collected each month.

Can property taxes affect my monthly mortgage payment?

Yes. If your property taxes are paid through escrow and the amount due increases, your lender may need to collect more each month to cover the higher bill.

Should I know my home's value even if I'm not selling?

Absolutely. Understanding your home's approximate market value can help you stay informed about your equity and the local real estate market, even when you don't have immediate plans to move.
