Should You Pay Off Your Mortgage Early or Appeal Your Property Taxes First?
Paying down your mortgage and appealing your property taxes both lower what you spend on your home. This post compares the two, shows why an appeal is often the cheaper first move, and explains how to think about doing both.
The short answer
You don't have to pick one. But if you're deciding which to do first, checking whether you can appeal your property taxes is usually the easier step. It costs little or nothing up front, takes far less money than extra mortgage payments, and the savings can repeat every year.
Here's why.
What extra mortgage payments actually save
Every extra dollar you send to principal stops earning interest for the lender. The savings depend on your interest rate and how much time is left on the loan.
Take a hypothetical $300,000 loan at around 6.5%. If you add $200 a month:
- You put an extra $2,400 toward principal in the first year.
- First-year interest savings are modest, often in the range of $100–$200.
- Over the full life of the loan, the savings can reach tens of thousands of dollars, and you may finish several years early.
That is a real benefit. But it comes slowly, and it takes a steady stream of cash. You also can't easily get the money back out. Extra principal is tied up in your home unless you sell or borrow against it.
Your numbers will differ. A lower rate means smaller savings from prepaying. A higher rate means larger ones.
What a lower assessment can save
Your property tax bill is based on your home's assessed value times your local tax rate. If the assessed value is higher than it should be, you pay more than your fair share.
Here is a hypothetical. Say your home is assessed at $350,000 but a fair value is closer to $315,000, about 10% lower. If your effective tax rate is somewhere around 1%–2%, that gap could mean roughly $350–$700 a year in tax.
Actual savings vary widely by state, county, and home. Some homeowners save a few hundred dollars a year. Others save well over $1,000. Some find their assessment is fair and save nothing.
The important part is that you don't have to spend $2,400 to get the savings. You file an appeal, and if it works, the lower value applies going forward.
Side-by-side comparison
| Extra mortgage payments | Property tax appeal | |
|---|---|---|
| Upfront cash needed | Ongoing, often hundreds per month | Little to none; some places charge a small filing fee |
| Typical first-year savings | Often $100–$200 in interest (on $2,400 extra paid) | Often a few hundred dollars or more, if over-assessed |
| Money tied up | Yes, locked into home equity | No |
| Guaranteed? | Yes, interest savings are certain | No, an appeal may not succeed |
| Ends when loan is paid off? | Yes | No, taxes continue as long as you own the home |
These are general ranges, not predictions for your home.
Why property taxes don't go away when the loan does
This is the point many homeowners miss. When you pay off your mortgage, the principal and interest payment ends. The property tax bill doesn't.
You will keep paying property taxes for as long as you own the home. If your loan payment includes an escrow account, your lender is just collecting taxes along with your payment. Once the loan is gone, that bill comes to you directly.
That has two effects:
- A fair assessment pays off for as long as you own the home, not only until the loan ends.
- If you're over-assessed, extra payments to the lender won't fix it. You may end up paying down a mortgage while also overpaying the county.
An accurate assessment helps lower the monthly cost of owning a home in both stages: with a mortgage and after it.
Risks and limits to know about
An appeal is a low-cost step, but it isn't risk-free or guaranteed.
- It may not work. If your value is already in line with comparable homes, the board may leave it unchanged.
- Values can go up. In some places, a board has the power to raise an assessment after review. This is uncommon but possible, so check your local rules.
- Savings may not be permanent. Your county will reassess again at some point, and your value may change. You may need to appeal again.
- Rules and deadlines differ. Appeal windows, forms, and standards vary by state and county. Confirm specifics with your county assessor's office.
Extra mortgage payments carry a different kind of risk. The savings are certain, but you give up flexibility. If you need cash for repairs, a job loss, or medical bills, it's hard to get it back out of your home.
A sensible order of operations
This is general information, not legal or tax advice. But for many homeowners, this order makes sense:
- Check your assessment. Compare it to recent sales of similar homes nearby, and look for errors in square footage, bedroom count, or condition.
- Appeal if it looks high. Look up your county's deadline first. Many are only open for a short window each year.
- Cover the basics. Keep an emergency fund and pay off higher-interest debt like credit cards before prepaying a low-rate mortgage.
- Then add extra principal if it fits your budget and you value being debt-free sooner.
If your mortgage rate is high, prepaying becomes more attractive. If it's low, your money may do more elsewhere. Either way, an appeal costs little to try and doesn't compete with your other goals.
How much does an appeal cost?
It depends on how you do it.
- Doing it yourself often costs only your time, plus a small filing fee in some areas. You'll need to gather comparable sales and learn your county's process.
- Hiring a service costs money, but the model matters. With TaxedFairly, we research your home, file the appeal, and charge 20% of first-year savings. If we don't win, you owe nothing.
For example, if an appeal saved $500 in the first year, a 20% fee would be $100, leaving you with $400, and the lower value could keep helping in later years.
The bottom line
Paying off your mortgage early is a solid goal, but it's slow and it takes real cash. Appealing your assessment is often faster and cheaper to try, and it targets a bill that continues long after your last mortgage payment.
