Quick Answer
Property taxes are annual taxes assessed by local governments based on your home's value, and they vary dramatically across the United States. According to the Tax Foundation's 2025 analysis, effective property tax rates range from 0.29 percent in Hawaii to 2.47 percent in New Jersey. On a 350,000 dollar home, that difference translates to 1,015 dollars per year in Hawaii versus 8,645 dollars per year in New Jersey, a 7,630 dollar annual gap.
Property taxes are one of the most significant ongoing costs of homeownership, yet many buyers do not fully account for them when budgeting for a home.
How Are Property Taxes Calculated?
Property taxes are assessed by local governments, typically counties or municipalities, based on the assessed value of your property. The revenue funds public services including schools (which receive the largest share at approximately 45 percent of property tax revenue nationally, according to the National Conference of State Legislatures), fire departments, road maintenance, and local government operations.
Property tax formula: Assessed Value x Tax Rate (Mill Rate) = Annual Property Tax
For example, a home assessed at 300,000 dollars with a tax rate of 1.2 percent would owe 3,600 dollars per year, or 300 dollars per month added to your mortgage payment.
Why Do Property Tax Rates Vary So Much Between States?
Property tax rates are set locally, which means they can differ dramatically not just between states but between neighboring counties and cities. Several factors drive these differences:
- State funding models: States that rely heavily on property taxes for school funding (like New Jersey and Connecticut) tend to have higher rates.
- Income tax offset: States with no income tax (Texas, Florida, Tennessee, Nevada) often have higher property taxes to compensate.
- Assessment methods: Some states assess homes at 100 percent of market value, while others use a fraction (Georgia assesses at 40 percent of market value).

| Connecticut | 2.15% | $7,525 | Heavy school funding reliance |

| New York | 1.72% | $6,020 | Varies widely (NYC vs. upstate) |

How Do Property Taxes Affect How Much Home I Can Afford?
When calculating how much home you can afford, always factor in property taxes. Your mortgage payment includes principal, interest, taxes, and insurance (PITI). A home with a lower purchase price in a high-tax state might cost the same monthly as a more expensive home in a low-tax state.
Monthly cost comparison example:
| Factor | New Jersey ($350K home) | Colorado ($350K home) | Difference |
|---|---|---|---|
| Monthly property tax | $720 | $149 | $571 |
| Equivalent borrowing power of that difference | - | +$100,000 in mortgage capacity | Based on 6.5% rate |
That 571 dollar monthly difference in property taxes is equivalent to roughly 100,000 dollars in additional mortgage borrowing power, meaning you could afford a significantly more expensive home in the lower-tax state for the same monthly payment.
What Property Tax Exemptions and Protections Are Available?
Most states offer some form of property tax relief. According to the Lincoln Institute of Land Policy, the most common programs include:
| Exemption Type | How It Works | Example |
|---|---|---|
| Homestead exemption | Reduces assessed value for primary residence | TX: $100K school tax exemption |
| Senior exemption | Additional reduction for homeowners 65+ | FL: additional $50K exemption |
| Veteran exemption | Reduction for military veterans | VA: 100% exemption for disabled vets |
| Assessment caps | Limits annual assessed value increases | CA Prop 13: 2% annual cap |
| Circuit breaker | Tax credit when taxes exceed income % | MN: refund if taxes > 2% of income |
Ask your Homexa® agent about the specific exemptions and protections available in your target market. These can make a meaningful difference in your annual costs.

Property taxes are a significant and often overlooked factor in the true cost of homeownership. Understanding how they work in your target area helps you budget accurately and avoid surprises after you close.
