Hidden Costs of Owning a Home Now Run $16,566 a Year, and Insurance Is Rising Fastest

Key Takeaways: The hidden costs of owning a home now run $16,566 a year, about $1,380 a month on top of a mortgage payment, according to a Zillow and Thumbtack analysis released October 22, 2026. Maintenance accounts for $11,171 of that total, property taxes for $3,129, and homeowners insurance for $2,266. The total is up 31.7% over five years, but just 2.8% in the past year, and insurance is the fastest riser of all, up 54% in five years.

That split is the fresh insight here. The second mortgage hiding inside every home is no longer surging the way it was, yet one line inside it, insurance, has quietly overtaken property taxes in four major metros. For a beginner investor, that changes which number deserves the closest look before an offer, not after closing.

The $1,380-a-Month Bill That Sits on Top of the Mortgage

The Zillow and Thumbtack analysis counts three costs every owner pays: maintenance, property taxes, and homeowners insurance. None of them appears in the listing price, and together they now average more than many rent payments.

Hidden cost	Per year	Per month	5-year change
Maintenance	$11,171	About $931	+32%
Property taxes	$3,129	About $261	+19%
Homeowners insurance	$2,266	About $189	+54%
Total	$16,566	About $1,380	+31.7%

Zillow Senior Economist Kara Ng said: "Many households focus so much on winning the home and underestimate what it costs to live in it."

She added: "Long after they receive the keys, insurance, taxes and upkeep are recurring expenses to plan for. Since these homeownership costs vary so much by market, home shoppers should run the numbers and understand what they can truly afford before they make an offer."

The market spread is wide. Total hidden costs are highest in New York at $25,111 a year, followed by San Francisco at $24,383, Los Angeles at $22,915, and Boston at $22,096. Even the least costly metro analyzed, Phoenix, runs $14,187 a year.

That gap matters in a scarce-buyer market. Realtor.com reported homes under contract fell 10.5% year over year in October as mortgage rates averaged 7.33%, so a buyer who misjudges carrying costs has little room to recover.

Insurance Is Now the Line to Watch

Insurance premiums have jumped 54% over five years, faster than maintenance at 32% and property taxes at 19%. Premiums rose at least 50% over five years in 19 of the 30 metros analyzed, led by Dallas at 75%, Tampa at 71%, Denver at 70%, and Houston at 69%.

• Highest premiums: Miami homeowners pay the most, at nearly $5,000 a year.
• Over $3,000 a year: six metros now clear that mark: Miami, Dallas, Houston, Tampa, Orlando, and Denver.
• Insurance beats taxes: homeowners in Houston, Phoenix, Denver, and Nashville now pay more each year for insurance than for property taxes.
• Maintenance still dominates: it is the largest hidden cost in every metro, at roughly two-thirds of the national total, and it tops $12,000 in six major metros, including Seattle at $12,594 and Boston at $12,486.
• Sharpest maintenance jump: Los Angeles rose 27% year over year, which Zillow linked to wildfire-related recovery efforts, demand for home services, and elevated labor costs.

There is one piece of relief in the release. The pace is cooling: total costs rose just 2.8% in the past year against 31.7% over five years, yearly maintenance increases have shrunk from 9% in 2022 to 1% in 2026, and federal data cited by Zillow shows insurance premiums rose just 0.3% between February and June 2026.

Thumbtack home trends expert Kendra Sinclair said: "The slowdown in maintenance cost growth is welcome news for homeowners managing a lot of competing expenses."

She added: "Planning for regular upkeep throughout the year can help prevent bigger repair bills and protect your savings when something unexpected happens."

Cooling costs still sit on high borrowing costs. Mortgage applications fell 1.2% in the week ending October 30 even as the 30-year rate eased to 7.30%, a sign buyers weigh the full monthly load, not the rate alone.

What Beginner Investors Should Do With These Numbers

1. Add $1,380 a month to your first pass, then replace it with local numbers. Use the national $16,566 as a starting reserve, then price the specific metro. A New York deal at $25,111 a year and a Phoenix deal at $14,187 a year cannot share the same expense line.
2. Get a real insurance quote before you make an offer. Zillow gives the same advice to home shoppers, and the five-year data shows why: premiums are up 54% nationally and at least 50% in 19 of 30 metros. A quote that comes in high can change what the property is worth to you.
3. Underwrite maintenance as the biggest cost, not a rounding error. At $11,171 a year, maintenance is roughly two-thirds of the total. Ask for the age of the roof, heating and cooling system, and water heater, and budget for the oldest item first.
4. Check whether insurance beats taxes in your metro. In Houston, Phoenix, Denver, and Nashville it already does. If your spreadsheet assumes taxes are the larger bill, your cash flow estimate is built on an old pattern.
5. Do not count on the cooling pace to rescue a thin deal. Costs rose 2.8% in the past year, and home prices are still moving slowly, with the Case-Shiller index up 2.1% in the year through August. A deal needs to work at today's carrying costs, not at a hoped-for drop.

The bottom line: the purchase price is only the first price of a home. The second price is $16,566 a year, it varies by more than $10,000 between the cheapest and costliest metros in this analysis, and its fastest-growing piece is insurance. Run that second price before you offer, and a lot of bad deals will screen themselves out.
