Franklin County Homestead and Your Columbus Mortgage Payment in 2026

Columbus mortgage payment surprises happen every fall when buyers realize their monthly property tax escrow comes in higher than expected. The listing shows a property-tax number, the payment looks comfortable, and the real monthly escrow comes in higher. The gap is often the Franklin County homestead exemption on the seller’s bill. That credit belongs to the person who qualified. It does not come with the house.

Joe is the broker-owner of Sauk Mortgage Group, an independent mortgage broker at 1880 Mackenzie Drive, Suite 107, in Upper Arlington. He has originated mortgage loans since 1993. Sauk Mortgage Group Ltd. is licensed in Ohio and Florida. This guide is about Franklin County property tax and the mortgage payment on a Columbus-area purchase or refinance. The Franklin County Auditor decides who qualifies for homestead. Joe uses that answer so the tax line in your estimate is not a guess.

If you want the short version before the detail: copy the parcel’s taxing district, do not assume the seller’s homestead, and have Joe compare your best mortgage options with that tax included. The county rules below are what the Auditor publishes for the 2026 application period.

Why Property Tax Impacts Your Columbus Mortgage Payment

A mortgage payment is principal, interest, and, on most loans, an escrow for property tax and homeowners insurance. The lender collects about one-twelfth of the annual tax bill each month, then pays the county when the bill is due. If the annual tax in the estimate is wrong, the monthly number is wrong by the same fraction, every month you own the home.

Franklin County does not use one tax rate for every address. Upper Arlington, the Columbus school district, Dublin, Worthington, Hilliard, Westerville, Gahanna, Grove City, and New Albany sit in different taxing districts. Two houses at the same price can produce different tax bills because the schools and the other local levies are different. A payment built from a county average, or from a friend’s house two suburbs over, is not a payment for the house you are offering on.

The other common miss is the seller’s bill itself. Ohio looks at who owned and occupied the property on January 1 when it sets that tax year’s credits. If the seller qualified for homestead, their bill is lower than the bill a buyer who does not qualify will pay later. Prorating that lower bill at the closing table is a one-time split between buyer and seller. It is not your monthly payment for the years after you own the home.

Joe’s job, before you write the offer, is to put the tax you are likely to escrow next to the principal and interest. Conventional, FHA, VA, and jumbo loans each treat down payment and mortgage insurance differently. The tax escrow sits on top of all of them. A prettier rate with a homestead bill copied from the seller can lose to a plainer rate with the real tax.

What the Franklin County Auditor says homestead does in 2026

Homestead is a statewide property-tax credit. It is not a loan program, not an Ohio Housing Finance Agency grant, and not a cut to your interest rate. The Franklin County Auditor describes it as a reduction that shields part of the auditor’s appraised value from taxation. The credit shows up on the tax bill. It does not hand you cash at the closing table.

On the Auditor’s homestead page, the figures in use for Franklin County applicants are:

• Senior citizens and permanently and totally disabled homeowners: the first $29,000 of the home’s appraised value is exempt. The Auditor’s own example is a home appraised at $100,000 that is billed as if it were valued at $71,000.
• Disabled veterans who qualify for the enhanced exemption, and surviving spouses of public service officers killed in the line of duty: the first $58,000 of appraised value is exempt. The Auditor’s example is a home appraised at $100,000 that is billed as if it were valued at $42,000.

The dollar savings are not the same in every city. The Auditor says the exact credit depends on the local tax rate and publishes an estimated reduction schedule by tax district. A $29,000 reduction in value in Upper Arlington is not the same dollar credit as a $29,000 reduction in another district. Use the schedule for the district on the parcel. Do not convert the Auditor’s $100,000 example into your monthly payment. That example is there to show the value shield, not to quote a mortgage.

These amounts are what the Franklin County Auditor is publishing for people applying now. The reduction is adjusted over time. Before you count on a dollar figure, reopen the Auditor’s homestead page and the FAQ. Sauk Mortgage Group will not treat a screenshot from last year as this year’s credit.

You can read the Auditor’s overview at auditor.franklincountyohio.gov/Real-Estate/Homestead and the rules in the homestead FAQ.

Who can apply, and the December 31 deadline

For the senior and disabled homestead exemption, the Auditor’s FAQ requires all of the following.

You own and occupy the home as your primary residence as of January 1 of the year you are applying for. For a 2026 real-property application, that date is January 1, 2026.

You are 65, or you turn 65, by December 31 of that year. Or you are totally and permanently disabled as of January 1, with the certification the Auditor accepts. Or you are the surviving spouse of a person who was receiving homestead at death, and you were at least 59 on the date of death.

Household income stays under the cap, unless you are grandfathered. For the 2026 application period, the Auditor’s maximum is $41,000 of total income in 2025, for you and your spouse together. Total income here means modified adjusted gross income: Ohio adjusted gross income plus any business income deduction. Homeowners who received homestead for tax year 2013 are not subject to the income test. They are grandfathered. They still submit form DTE 105G to confirm that status. A grandfathered owner who moves still has to reapply at the new address. The old approval does not follow them.

If one owner is 65 or disabled and the home is that person’s primary residence, the Auditor says the property may still qualify when the other spouse is younger, as long as the income test is met.

Real-property applications are due on or before December 31 of the year you want the exemption. For 2026, that is December 31, 2026. Manufactured and mobile homes use the prior calendar: the application is due December 31 of the year before the year you want the credit, and the age rule is shifted. If the home is a manufactured home, use the Auditor’s manufactured-home dates. Do not assume the house deadline applies.

The forms the Auditor names are:

• DTE 105A for senior citizens, disabled persons, and surviving spouses. An electronic application is available.
• DTE 105E, the disability certificate, if you are under 65 and claiming permanent and total disability. A physician or psychologist licensed in Ohio signs it, or you provide a current certificate from an agency such as Social Security that the Auditor accepts. The disability has to prevent substantial employment as of January 1, and the paperwork should show the onset date.
• DTE 105H if neither you nor your spouse had to file a federal or Ohio income-tax return.
• DTE 105I for the enhanced disabled-veteran exemption, with a copy of the DD214 and the VA award letter showing a 100 percent rating, or compensation at 100 percent plus individual unemployability.
• DTE 105K for a surviving spouse of a public service officer killed in the line of duty, with written confirmation from the department, agency, or pension fund. That reduction applies to one homestead.

The enhanced veteran credit is a property-tax reduction. It is not the same thing as a VA home loan. A Central Ohio veteran can use a VA loan to buy and still need DTE 105I, the DD214, and the award letter before the larger homestead credit exists. Sauk Mortgage Group can originate the VA loan. The Auditor approves or denies the exemption. Those are two separate yes-or-no answers.

If the home is titled in a trust, the Auditor’s FAQ still has a path. A settlor of a revocable or irrevocable trust who occupies the home as of right under the trust can be treated as an owner. A trustee who meets the other tests can qualify as well. The Auditor asks for the trust pages that identify the parties, plus the signature and notarization pages. Send those with the application. Do not assume a trust blocks the credit, and do not assume the trust gets it automatically.

The Auditor verifies income against Ohio returns when it can. If it cannot, it asks for the Ohio IT 1040 and Ohio Schedule A, or the federal return if you had no Ohio return. Current applications that need that income check are reviewed beginning in May, after most returns are processed. If you apply in January before your 2025 Ohio return is done, the Auditor says the decision waits until the Department of Taxation has processed the return and the office has confirmed the income is at or under $41,000.

Applications are processed in the order received. You receive a certificate within 30 days after processing that says approved or denied, and a denial states the reason. If you think the denial is wrong, form DTE 106B is the complaint to the county Board of Revision, and the FAQ gives you 60 days from the notice to submit it.

A fall purchase does not inherit the seller’s credit

This is the part that changes an October offer in Franklin County.

If you close in October, November, or December 2026, you did not own and occupy that house on January 1, 2026. The FAQ is direct: you must own and occupy the home as of January 1 to qualify for that tax year, and the exemption does not take effect at a new home right away. The tax status on January 1 controls the credits for the whole tax year.

So the seller’s homestead is not a feature you can underwrite into your offer. If you are buying from a homeowner in Worthington, Hilliard, or Columbus who has had the credit for years, their bill can look modest for the neighborhood. Your bill, once you are the owner the county is taxing without that credit, can be the full district amount. Joe builds the purchase estimate on the tax you will escrow, not on the seller’s reduced bill.

When you move, you reapply at the new address in the following application period, even if you were grandfathered. The Auditor says to complete DTE 105A, and DTE 105G if you need to confirm grandfather status, beginning in January of the year after you move. A buyer who closes in fall 2026 and lives in the home on January 1, 2027 is looking at that next application period for the next tax year. The income cap is reset by law. Do not assume the 2026 cap of $41,000 is the cap in a later year. Read the FAQ again when that application opens.

People who already own and occupy a Franklin County home, and who meet the 2026 tests, are in a different spot. Their deadline is December 31, 2026. A current-year approval shows up on the tax bill due the following year. A late applicant who is approved is entitled to the credit on taxes paid in the current year. Depending on whether that bill is still open, the Auditor either applies the credit to the next bill or refunds it. That is the Auditor’s rule for late applications. It is not a lender credit.

When the monthly payment actually changes

Approval is not the same week as a lower draft. The Auditor’s FAQ answers the mortgage question in one place: your mortgage company reviews escrow once or twice a year, and if you are approved for the current tax year you see the payment change sometime next year. Contact the servicer for the month they run that review.

Plan the household budget on that timing. A certificate in the fall does not rewrite this month’s payment. If you are refinancing, Joe can put the tax figure he can document on the new loan estimate. He cannot make the county post a credit early, and he cannot promise the servicer will analyze escrow on a date the Auditor did not set.

There is a second timing trap for people who already have a loan. The exemption reduces the tax bill. The servicer may still be collecting the old, higher tax until the analysis catches up. When it does, the payment can drop, or you can receive an escrow surplus, under the servicer’s own rules. Ask the servicer which of those they do. Do not spend a surplus that is not in your account yet.

None of this is a reason to skip the application if you qualify and you already own the home. A credit you never request is a tax bill you keep paying. It is a reason to keep the mortgage estimate and the county form on two different calendars.

What Joe checks before you write the offer

On a Franklin County purchase, Joe looks at four items that move the payment more than a headline about rates.

The parcel and the taxing district. He wants the address that will be on the deed, not a zip-code average for “Columbus.”

Whether the current tax bill includes homestead, or any other reduction tied to the current owner, that will not be yours after January 1.

Which loan fits the rest of the picture. A VA buyer, an FHA buyer, and a conventional buyer can look at the same house and still have different mortgage insurance, funding fees, and down payments. The tax line is added after that choice. Sauk Mortgage Group shops more than one lender. The point of that shop is to compare your best mortgage options with the payment you will actually make, tax included.

Cash to close versus the monthly payment. Homestead, once you qualify in a later year, can change the escrow. It does not replace a down payment, and it is not the OHFA assistance Joe writes about on other pages. If you need help with cash at closing, that is a different conversation, and it should not be mixed into the homestead credit.

You can run a rough payment on the mortgage calculator. Treat it as an estimate. Then send Joe the address so the tax line can be replaced with the district figure. The pre-qualification form is on the apply page. The office hours posted on the contact page are Monday through Friday, 8 a.m. to 6 p.m. The team, including who is licensed, is on the team page.

Joe is a mortgage broker. He is not the Auditor, and this article is not tax advice. If your age, disability, income, trust, or veteran status is close to a line in the FAQ, ask the Auditor before you count on the credit. The office that publishes these rules is the Franklin County Auditor, 373 S. High Street, Columbus.

Questions Columbus buyers ask

Does homestead lower my interest rate?

No. It reduces the taxable value of the home. The rate, term, and mortgage insurance on the loan are a separate decision. A credit on the tax bill can lower the escrow portion of the payment later. It does not reprice the loan.

I am buying from a senior in Dublin or Worthington. Do I get their exemption at closing?

No. The Auditor says the exemption does not transfer when you move, and the buyer of their home is in the same spot. You apply on your own record after you own and occupy the new home as of January 1. Until then, build the payment without their credit.

I already live in Grove City and I turn 65 in November 2026. Can I apply for 2026?

For real property, the Auditor says you must be 65 by December 31 of the year you apply, and you must have owned and occupied the home as your primary residence on January 1 of that year. If both are true for 2026, the deadline is December 31, 2026. Income for this period is 2025 income, capped at $41,000 unless you are grandfathered from tax year 2013. If you bought the Grove City house after January 1, 2026, you were not the January 1 owner, so this year’s application is not available to you. You look at the next period.

Will my mortgage payment drop the month I am approved?

Not on the timeline the Auditor publishes. A current approval is reflected on the tax bill due the following year. The mortgage company adjusts the monthly payment at its next escrow analysis, which the Auditor describes as sometime the next year. A late approval can produce a credit or refund on taxes already billed, under the Auditor’s late-application rule. Ask your servicer which review month they use.

Is the disabled-veteran homestead the same as a VA loan?

No. The enhanced exemption shields the first $58,000 of appraised value for a veteran who meets the Auditor’s disability test, and for certain surviving spouses. A VA loan is a mortgage. You can qualify for one, the other, or both. Joe can walk through the VA loan with you. The Auditor decides the tax credit after it has the DD214 and the award letter.

My spouse is under 65. Does that block us?

Not by itself. If you are 65 or disabled, the home is your primary residence, and the household income test is met, the Auditor says the property may still qualify.

We put the house in a trust. Is homestead off the table?

Not automatically. The Auditor’s FAQ treats certain settlors and trustees as owners if the other tests are met, and it asks for specific trust pages with the application. Read that section of the FAQ and send what they list. Do not skip the application only because a trust is on the deed.

What to do this month

If you already own and occupy a Franklin County home and you meet the 2026 tests, start the Auditor’s application now. Income checks that depend on the 2025 Ohio return are not finished in October. Waiting until the last week of December puts you behind everyone else in the same stack, and the office processes in the order received.

If you are buying this fall, ask Joe for a payment that leaves the seller’s homestead out. Bring the address, the listing tax figure, and whether anyone has told you the seller “has a senior exemption.” That sentence is useful. It is also the reason not to trust the listing tax as your future payment.

Then compare the loan on that payment, not on a rate pulled off a billboard. Conventional, FHA, VA, and jumbo are all tools Sauk Mortgage Group actually uses. The right loan is the one that fits your budget after calculating an honest Columbus mortgage payment.
