Iowa Mortgage Calculator
High property tax rates paired with low Midwestern purchase prices.
Iowa’s effective property tax rate averages ~1.50% of market value. Iowa uses a state "rollback" percentage to calculate taxable value from market value.
The Iowa Homestead Tax Credit provides direct tax relief for primary homeowners, offsetting higher local school district levies.
Assumptions & Review
Last reviewed: August 2026 · The Mortgage Curve editorial team
These are rough planning assumptions, not precise quotes. The tax figure is a dated state-level effective-rate reference; the insurance figure is an editorial percentage estimate. Your actual property tax depends on your county, city, school district, and assessed value, and your insurance premium depends on your carrier, coverage, deductible, and local risk.
Methodology: the tax percentage is a 2024 owner-occupied effective-rate planning reference; insurance and home-price figures are editorial estimates informed by public data and reviewed in August 2026. Verify them with your county assessor, insurer, or lender before relying on the estimate. See the U.S. Census housing data reference.

What's Different About Iowa?
Property Tax
Average effective rate ≈ 1.50% of market value. State rollback ratio determines what percentage of market value is subject to tax.
Homeowners Insurance
Rough state-level estimate ≈ 0.60% of home value per year. Hail and severe windstorms impact rural and suburban premiums.
Local Variation
- Property Tax Rollback: State sets annual rollback percentage (typically ~54-56%) limiting residential taxable value growth.
- Homestead Tax Credit: Reduces taxable value of qualifying primary homes by up to $4,850.

Iowa Mortgage FAQs
State-level defaults explained, and why your real numbers will differ.
1How is this state mortgage estimate calculated?
It uses the standard fixed-rate amortization formula for principal and interest, then adds a rough state-level property tax estimate and a rough state-level homeowners insurance estimate. Tax and insurance are based on percentages of home value, not a precise quote.
2Why is this not a precise quote?
These are state-level defaults meant for quick comparison. Your actual property tax depends on your county, city, school district, exemptions, and assessed value, and your insurance premium depends on your carrier, coverage, deductible, and local risk. Replace the defaults with your own figures in the calculator for a more accurate estimate.
3How do I get a more accurate estimate?
Open the prefilled calculator for the state, then update the property tax and insurance estimates with the figures from your tax bill, insurance quote, or lender's Loan Estimate. The calculator updates in real time and runs entirely in your browser.
4How does Iowa’s property tax rollback work?
Iowa applies a statewide rollback factor that scales down market value to taxable value, preventing runaway tax increases during market booms.
