Iowa assessors revalue homes in every odd-numbered year, and the state then applies a residential rollback: only a set share of the assessed value is taxable, and the Department of Revenue recalculates that share each year to limit statewide growth in taxable values. The levy rates of the county, the city or township, the school district and the community college are applied to what is left.
New owners need to claim the homestead credit with the city or county assessor. It is available only on a home you occupy as your main residence, and once on file it stays until the home is sold. Recent legislation added a larger exemption for homeowners past retirement age and placed new limits on how fast local budgets may grow, so the details on a bill from a few years ago may no longer apply. Veterans can claim a military service exemption, and low-income seniors and people with disabilities can apply for a separate credit.
One part of the closing process is unusual. Iowa is the only state where private companies do not sell title insurance on Iowa property. Instead, the state housing finance authority runs Iowa Title Guaranty, which issues certificates that protect lenders and owners, and an abstract of title prepared by a local attorney is still part of most sales.
Property tax is paid in arrears, in two halves due in early autumn and early spring. A modest real estate transfer tax is collected when the deed is recorded. Buyers in river towns should check flood maps after the floods of recent decades.
Property tax in Iowa
The median Iowa homeowner pays $2,897 a year in property tax on a home valued at $208,000, an effective rate of 1.3928% in the Census Bureau's American Community Survey (ACS 5-year 2020-2024). That ranks the 10th highest of the 50 states and DC, above the middle state's 0.8003%. At that rate each $100,000 of home value carries about $1,393 a year of tax, or $116.07 a month in the payment, and that rate is what the calculator above starts from.
Inside Iowa the rate more than doubles from the cheapest county to the dearest. Among counties whose survey figures pass both quality checks, the effective rate runs from 0.8674% in Lyon County to 1.8008% in Union County. On a $208,000 home that gap is worth about $1,941 a year. Pick a county in the calculator to use its rate, or type the rate from a listing or a current tax bill.
A high effective rate in Iowa reflects what owners actually pay after exemptions and caps, so the rate in the calculator is the one that matters for a budget, not any rate printed in Iowa law. Ask for the seller's latest bill and the assessed value too, since a new owner's assessment can differ from the long-held homes behind the median.
Iowa property tax rates by county
All 99 counties, sorted from the highest effective rate to the lowest. The rate is the median tax paid divided by the median home value, from the ACS 5-year 2020-2024 survey (figures to December 31, 2024). Of these, one carries a flag: where the survey's margin of error is wide or home values hit the survey's top code, the calculator uses the Iowa median instead of that county's figure.

Worked example: the median Iowa home
The median owner-occupied home in Iowa is valued at $208,000 (ACS 5-year 2020-2024). Put $41,600 down, enough to keep the loan at 80% of the price so no PMI is charged, and borrow the rest over 30 years at 7.4%, the Freddie Mac average for the week of October 15, 2026. Insurance is the calculator's default of $1,500 a year, the same figure on every state page and 8.2% of this payment; real premiums vary widely from state to state and with a home's exposure to wind, flood and wildfire, so replace it with a premium for the Iowa home you are pricing.
| Line | A month | A year |
|---|---|---|
| Principal and interest | $1,152.12 | $13,825.44 |
| Property tax | $241.42 | $2,897.04 |
| Homeowners insurance | $125.00 | $1,500.00 |
| Private mortgage insurance | $0.00 | $0.00 |
| Total payment | $1,518.54 | $18,222.48 |
Principal and interest dominate the bill; tax and insurance, usually collected through escrow, add $366.42 a month, 24.1% of the total. Over the full term the $166,400 loan costs $248,363 in interest.
With $20,800 down instead, the loan grows to $187,200 and PMI of $78.00 a month is added, for a first payment of $1,740.55. On the regular schedule the PMI stops after 10 years, with the payment in October 2036. A 15-year loan at the 6.71% average, with the larger down payment, raises the monthly figure to $1,835.22 but cuts the interest to $97,984.
What the median Iowa wage can buy
The median annual wage in Iowa is $48,540 (BLS wage survey, May 2025). Paid every two weeks as a single filer, that leaves about $3,319 a month after federal and Iowa paycheck deductions. With $60,000 saved for a down payment and $400 a month of other debts, the home affordability calculator's default 28/36 rule gives this range at 7.4% and the Iowa property tax rate:
| Level | Home price | Monthly payment |
|---|---|---|
| Conservative | $89,091 | $430 |
| Target | $166,570 | $1,056 |
| Stretch | $201,594 | $1,339 |
Here the limit is total debt: the housing payment plus the other $400 a month reaches 36% of gross pay first. The target falls $41,430 short of the $208,000 median home value: the median home costs 4.3 times the median wage, so a typical Iowa purchase usually needs a second income, a larger down payment or a cheaper area.
Everyday costs help: Iowa's prices for goods and rent run 12.2% below the national average, by the Bureau of Economic Analysis price parities for 2024 (figures to December 31, 2024). That stretches the median wage to about $55,309 in national dollars.
Iowa mortgage questions
What is the mortgage payment on the median home in Iowa?
The median Iowa home is valued at $208,000 in the Census Bureau's ACS 5-year 2020-2024 figures. With $41,600 down and a 30-year loan at the 7.4% weekly average, the payment is $1,518.54 a month: $1,152.12 of principal and interest, $241.42 of property tax and $125.00 of insurance.
What is the property tax rate in Iowa?
Homeowners in Iowa pay a median of $2,897 a year on a median home value of $208,000, an effective rate of 1.3928%. That is the 10th highest of the 50 states and DC. It is a measure of what owners actually pay, not a rate set in law, and a new purchase can be taxed differently.
Which Iowa county has the highest property tax rate?
Among counties with reliable survey figures, Union County has the highest effective rate at 1.8008% and Lyon County the lowest at 0.8674%. On the $208,000 median home, that gap is about $1,941 a year.
How much house can I afford on the median Iowa wage?
On the median wage of $48,540, take-home pay is about $3,319 a month. With $60,000 down and $400 a month of other debts, the 28/36 rule points to a home of about $166,570, against a median home value of $208,000.
Does a smaller down payment change the Iowa payment much?
With $20,800 down on the same home the loan is larger and private mortgage insurance is added, so the payment starts at $1,740.55 a month, $78.00 of it PMI. The PMI stops once the scheduled balance reaches 78% of the original value.
