What Your Mortgage Payment Doesn't Tell You: The State-by-State Cost of Owning a Home

When a lender approves your mortgage application, the number on that approval letter can feel like the finish line. In reality, it represents only one layer of your annual financial obligation as a homeowner. Property taxes, homeowner's insurance premiums, and homeowners association (HOA) fees collectively constitute what industry professionals often call the "carrying costs" of ownership — and in many markets, they rival or exceed the cost of the mortgage itself.

For buyers navigating today's market, understanding these recurring expenses before closing is not merely prudent; it is essential. At House & Howell, we believe that finding your place means understanding every dollar attached to it. What follows is a state-by-state examination of these three cost categories and how they should inform your affordability calculations.

Property Taxes: The Most Variable Expense in Real Estate

No single cost fluctuates more dramatically across state lines than the property tax. Levied by local governments to fund schools, infrastructure, and public services, property taxes are calculated as a percentage of a home's assessed value — a figure that may differ from its market value depending on how your county or municipality conducts its assessments.

According to data from the Tax Foundation, New Jersey consistently records the highest effective property tax rate in the nation, hovering near 2.2% of assessed home value. On a $400,000 home, that translates to approximately $8,800 per year — or more than $730 per month added to your housing costs before insurance or HOA fees enter the picture.

Contrast that with Hawaii, which carries an effective rate closer to 0.28%. The same $400,000 home there would generate a tax bill of roughly $1,120 annually. Other low-tax states include Alabama, Colorado, and Nevada, all of which maintain effective rates below 0.6%.

High-tax states worth noting include Illinois (approximately 2.0%), Connecticut (1.8%), and Texas (1.6%). Texas is particularly instructive: despite having no state income tax, its property tax rates rank among the highest in the country, a trade-off that surprises many relocating buyers.

What buyers should do: Request the most recent tax bill for any property you are seriously considering and verify whether the current assessment reflects the sale price. In many jurisdictions, a sale triggers a reassessment, meaning the previous owner's tax bill may significantly understate what you will owe.

Homeowner's Insurance: Geography Is Everything

Homeowner's insurance premiums are priced according to risk — and risk, in the insurance industry, is largely a function of geography. Proximity to coastlines, fault lines, flood plains, and wildfire zones all influence what insurers charge to protect your property.

Nationwide, the average annual homeowner's insurance premium sits around $1,400 to $1,700, according to industry aggregators. But that average conceals enormous regional disparity.

Oklahoma, Kansas, and Nebraska — squarely within Tornado Alley — routinely see average premiums above $3,000 per year. Florida presents a unique challenge: hurricane exposure, combined with a state insurance market that has seen several major carriers exit in recent years, has pushed average premiums above $4,000 annually in many coastal counties, with some areas experiencing rates two to three times that figure.

California homeowners face escalating wildfire-related premiums, particularly in foothill and rural communities. Insurers have reduced their exposure in the state to such a degree that many buyers are being placed in the California FAIR Plan, the state's insurer of last resort, which offers more limited coverage at higher cost.

On the more affordable end, Hawaii, Utah, and Oregon tend to carry lower average premiums, though local conditions within each state can vary considerably.

What buyers should do: Obtain insurance quotes during the due diligence period — not after closing. In high-risk areas, the cost and availability of coverage can materially affect whether a purchase remains financially viable. Your lender will require proof of insurance before funding the loan, but you want to know the premium well before that point.

HOA Fees: A Cost That Buyers Frequently Underestimate

Homeowners association fees are perhaps the least understood component of housing costs among first-time buyers. Unlike property taxes and insurance, HOA fees are not universal — they apply only to properties within planned communities, condominium buildings, townhome developments, and certain single-family subdivisions.

When they do apply, however, they can be substantial. The Community Associations Institute estimates that over 74 million Americans live in communities governed by an HOA. Monthly fees nationally range from roughly $200 to $600 for single-family communities, while high-rise condominium buildings in major metros can charge $1,000 per month or more.

Geographically, HOA fees tend to be highest in dense coastal markets. New York City condominiums routinely carry monthly common charges exceeding $1,500. Miami, Los Angeles, and San Francisco similarly feature high-fee buildings, particularly in luxury segments. In Sun Belt retirement and resort communities — think Scottsdale, Arizona, or The Villages, Florida — fees can range widely depending on the level of amenities provided.

Beyond the monthly fee, buyers must also account for special assessments — one-time charges levied when an HOA's reserve fund is insufficient to cover a major repair. A new roof, elevator replacement, or parking garage rehabilitation can trigger assessments running into the tens of thousands of dollars per unit.

What buyers should do: Request the HOA's financial statements, reserve study, and meeting minutes for the past two years before closing. An underfunded reserve is a red flag that special assessments may be forthcoming. Review the CC&Rs (covenants, conditions, and restrictions) carefully, as they also govern what you can and cannot do with your property.

Building a True Affordability Calculation

Financial advisors and mortgage professionals frequently cite the "28/36 rule" — a guideline suggesting that housing costs should not exceed 28% of gross monthly income, with total debt not exceeding 36%. What matters for the purposes of this discussion is what counts as "housing costs."

A responsible affordability calculation should include:

• Principal and interest on your mortgage
• Property taxes (monthly escrow contribution)
• Homeowner's insurance (monthly escrow contribution)
• HOA fees, if applicable
• Private mortgage insurance (PMI), if your down payment is below 20%

Consider a practical example. A buyer in Austin, Texas, purchases a home for $450,000 with a 20% down payment. At a 7% interest rate on a 30-year fixed mortgage, principal and interest total approximately $2,394 per month. Adding Texas's effective property tax rate of roughly 1.6% ($600/month), a typical insurance premium ($175/month), and a neighborhood HOA fee ($150/month), the true monthly housing cost approaches $3,319 — nearly $1,000 more than the mortgage payment alone.

That same exercise performed in Memphis, Tennessee — with lower taxes, lower insurance, and fewer HOA-governed communities — would yield a materially different result, potentially making a higher-priced home more affordable in real terms than a modestly priced one in a high-cost state.

The Bottom Line

The sticker price of a home, and even the mortgage payment it generates, tells only a partial story. Savvy buyers treat the true carrying cost — taxes, insurance, and association fees combined — as a non-negotiable element of their financial analysis. These are not peripheral considerations; they are permanent obligations that will accompany you for as long as you hold the property.

At House & Howell, our guidance is straightforward: know every number before you sign. Your future self will thank you for the diligence.
