Mortgage Calculator by State: Why the Same Home Costs $600 More in New Jersey

The mortgage rate is the same. The home price is the same. But your monthly payment depends heavily on which state you are buying in. Property tax alone can swing your payment by $500 or more per month on the same loan.

Here is what a $350,000 home at 6.75% with 20% down looks like across high-tax and low-tax states.

State-by-State PITI Comparison

The principal and interest payment is constant: $1,817 per month on a $280,000 loan at 6.75%.

The property tax varies enormously:

| State | Avg Property Tax Rate | Annual Tax | Monthly Tax | Total PITI | |-------|----------------------|------------|-------------|------------| | New Jersey | 2.23% | $7,805 | $651 | $2,588 | | Illinois | 2.08% | $7,280 | $607 | $2,544 | | Connecticut | 1.79% | $6,265 | $522 | $2,459 | | New York | 1.54% | $5,390 | $449 | $2,386 | | Texas | 1.60% | $5,600 | $467 | $2,404 | | Ohio | 1.41% | $4,935 | $411 | $2,348 | | Florida | 0.83% | $2,905 | $242 | $2,179 | | Georgia | 0.83% | $2,905 | $242 | $2,179 | | Tennessee | 0.56% | $1,960 | $163 | $2,100 | | Arizona | 0.51% | $1,785 | $149 | $2,086 | | Alabama | 0.37% | $1,295 | $108 | $2,045 | | Hawaii | 0.28% | $980 | $82 | $2,019 |

Insurance estimated at $120/month for all states. Actual rates vary.

The Texas Illusion

Texas has no state income tax, which attracts buyers from California and New York. But Texas property taxes average 1.60%, among the highest in the country. On a $500,000 home, that is $8,000 per year, or $667 per month added to your mortgage payment.

A California buyer paying 1.05% property tax on the same $500,000 home pays $5,250 annually. The Texas property tax premium nearly offsets the income tax savings for many households.

Do the full calculation before assuming no-income-tax states are cheaper. They often are not for homeowners.

The Florida Double Factor

Florida property taxes vary widely by county. Broward County (Fort Lauderdale area) averages 1.07%. Miami-Dade averages 0.97%. But flood insurance can add $1,500 to $5,000 per year for coastal properties, a cost that does not appear in the headline property tax rate.

Always include insurance in the full payment calculation for Florida, coastal Texas, and Louisiana properties.

How Homestead Exemptions Change the Math

Most states offer homestead exemptions that reduce the taxable value of a primary residence. These are not automatic in many states. You have to file.

Texas: The standard homestead exemption removes $100,000 from assessed value for school district taxes. On a $350,000 home, taxable value drops to $250,000. At 1.6%, annual tax goes from $5,600 to $4,000. That is $133/month less.

Florida: Up to $50,000 exemption for primary residences. On a $350,000 home assessed at $350,000, taxable value drops to $300,000. Saves roughly $415 per year.

California: The Prop 13 homestead protection limits assessed value increases to 2% per year regardless of market appreciation. Long-term California homeowners often pay far less than the current market rate suggests.

Always apply for your homestead exemption. It is usually filed once and renews automatically.

The Assessment Lag Problem

Property tax is based on assessed value, not market value. In rising markets, there is often a lag. You may buy at $400,000 and be assessed at $370,000 the first year. The following year, the assessment catches up.

New owners in rapidly appreciating markets can see property tax bills jump 15-20% in year two. Budget for this. If your escrow was calculated on the purchase-year assessment, your lender will reassess and your payment will increase.

State Income Tax Offset

The states with the lowest property taxes are not universally the cheapest. Compare the total state and local tax burden:

• Texas: No income tax, 1.60% property tax
• California: 9-13% income tax, 0.73% property tax
• Florida: No income tax, 0.83% property tax
• Washington: No income tax, 0.84% property tax, higher sales tax

At $150,000 income, Texas has lower total taxes than California for most scenarios. But at $80,000 income in a low-cost area, the property tax premium in Texas may actually cost more than the California income tax.

Frequently Asked Questions

Which states have no property tax?

Every state has some form of property tax. Hawaii is the lowest at around 0.28%. There is no state with zero property tax on real estate.

Can I deduct property taxes on my federal return?

The federal SALT (State and Local Tax) deduction caps at $10,000 for married filing jointly. If your property taxes plus state income taxes exceed $10,000, you cannot deduct the excess. This cap most heavily impacts high-tax states like New Jersey, Connecticut, and New York.

What is Mello-Roos and how does it affect California buyers?

Mello-Roos is a special assessment district tax in California levied on new developments to fund infrastructure. It appears as a separate line item on your property tax bill and can add $2,000 to $6,000 per year to your annual costs. Always check for Mello-Roos before making an offer in California.
