Buying a home in Delaware, Ohio and trying to make sense of the tax line on your budget? You are not alone. Property taxes affect your monthly payment and long-term affordability, so understanding the basics can save you stress later. In this guide, you will learn how taxes are calculated in Ohio, how to estimate a bill for a Delaware property, and how escrow with your lender works. You will also get a practical checklist to verify numbers before you close. Let’s dive in.
In Ohio, property taxes are based on assessed value, not the full market price. Assessed value is a fraction of true market value that the state applies to real property. That means the number you offer for a home is not used directly to compute your tax bill.
Ohio also uses mills to set tax rates. One mill equals 1 dollar of tax per 1,000 dollars of assessed value. Your annual tax bill is generally calculated by multiplying the assessed value by the total millage rate for your specific parcel.
At a high level, the math looks like this:
Your total millage combines rates from several taxing units that apply to your property.
Two similar homes in Delaware can have different tax bills. That is because different taxing districts apply depending on the parcel’s boundaries. The largest share is often the school district levy. In the city of Delaware, many parcels fall under Delaware City Schools. Other components can include county operations, city or township services, libraries, parks, and special assessments.
When you view a parcel record, you will usually see each taxing unit listed, along with the rates that combine to form the total mills. This is why even within Delaware County, taxes can vary between neighborhoods, school districts, and townships.
You can build a solid estimate with a few steps. This is helpful for budgeting and for comparing homes.
Find the property’s market value. Use your offer price or a recent market value.
Determine the current Ohio assessment ratio for residential property. Multiply the market value by that percentage to get the assessed value.
Look up the combined millage for the parcel. Add the mills for county, school district, city or township, library, parks, and any special assessments.
Calculate the annual tax. Assessed value × (Total mills ÷ 1,000) = Estimated annual tax before credits or rollbacks.
Convert to monthly. Divide by 12 to estimate the monthly tax portion for your mortgage budget. If you plan to pay semiannually, divide by 2 instead.
Always verify the current assessment percentage and the millage rate for the specific parcel before you rely on a number.
The following example is for illustration only. Use actual parcel data for accuracy.
Several programs and timing events can affect your tax bill.
Rollbacks and owner-occupancy credits. Ohio authorizes state reductions that can lower taxes on owner-occupied residential property. Ask whether you need to apply after closing or whether credits transfer automatically.
Exemptions and special programs. Ask about senior or disabled reductions, veteran-related exemptions, income-based relief, or agricultural valuations when applicable. Your eligibility and any required applications are set by law and administered locally.
New construction and improvements. Additions, remodels, or new builds can increase assessed value when the county updates the tax roll. If you buy a home with recent improvements, plan for possible changes.
Reappraisals and value updates. Counties periodically reappraise properties. A reappraisal can change assessed values and tax bills even when millage does not change.
Levies and ballot issues. Voter-approved levies, especially for schools, can significantly change the tax rate. Check recent levy history and any upcoming ballot measures that affect your parcel’s districts.
Most lenders collect property taxes through escrow. This is how it typically works:
What escrow is. Your lender adds a monthly tax amount to your mortgage payment and holds it in an escrow account. The servicer then pays your semiannual tax bill when due.
Initial deposit at closing. Lenders usually collect an initial escrow deposit to cover the next bill. Expect a cushion, which federal rules allow, to prevent shortages.
Annual analysis. Your servicer performs a yearly escrow analysis to match projected tax bills. If your taxes rise, your monthly escrow portion may increase, or you may be asked to make a one-time shortage payment.
Questions to ask your lender.
Use this checklist to stay ahead of surprises and keep your budget accurate.
If you are comparing homes in Delaware, use the steps above to estimate taxes and confirm credits early. Then talk with your lender about escrow, and build a cushion in your monthly budget.
