Potential homebuyers tend to agonize over two things: mortgage rates and home prices. But that\u2019s not where the burden of homeownership ends. It\u2019s really just the beginning.<\/p>\n

\n

Buyers will lock in a rate, sign at closing, and assume the hard part of buying a house is over, but many things can go wrong, and there are many hidden homeownership costs that not everyone stops to consider.\u00a0<\/p>\n

For example, a recent survey of 2,500 U.S. homeowners from Ownwell, a property tax appeal service, found 76% say their property taxes in recent years have run higher than they budgeted for\u2014up 10 percentage points from just a year earlier. Nearly two-thirds said they were surprised or shocked by their most recent tax bill, and 9 in 10 said they\u2019re concerned about the long-term financial hit of rising property taxes. And even more startling is 40% said they had considered moving specifically because of them.<\/p>\n

\u201cTaxes have quietly joined insurance as one of the biggest affordability shocks after closing, especially in states with high property taxes like New York, Massachusetts, and Texas,\u201d Ownwell CEO Colton Pace told Fortune<\/em>.\u00a0<\/p>\n

These new stats point to an affordability problem the usual housing conversation misses. While it\u2019s more accessible (albeit sometimes painful) to monitor mortgage rates and home prices, recurring expenses like taxes, insurance, maintenance, and other line items that nobody mentions at the closing table are quietly reshaping what it actually costs to keep a home.<\/p>\n

\u201cThe fixed-rate mortgage was supposed to be the one predictable cost in your life,\u201d Pace said. \u201cRising insurance and property taxes have quietly broken that promise.\u201d<\/p>\n

The unpredictability of homeownership<\/h3>\n

A 30-year fixed mortgage is the rare household bill that doesn\u2019t change month-over-month or year-over-year\u2014but the taxes and insurance bundled into the monthly payment do. Every year, taxes and insurance can change a county-by-county schedule or at renewal, respectively.\u00a0<\/p>\n

\u201cHomeowners aren\u2019t tracking two separate bills,\u201d Pace said. \u201cThey\u2019re waiting for an escrow letter or a county notice of value to tell them their payment just changed.\u201d<\/p>\n

The math behind those notices has gotten harder to predict. The average sales price of new homes rose roughly 23% on average over the past five years, according to Federal Reserve data, and tax assessments followed. Property taxes reset annually and hinge on factors\u2014local housing markets, county and city budgets, and the tax rates that flow from them\u2014that even economists struggle to forecast, Pace said. That means homeowners can get hit with an unexpected amount.<\/p>\n

What agents tell buyers they\u2019re missing<\/h3>\n

Real estate agents see the same blind spots in their clients.<\/p>\n

\u201cBuyers seem to be more focused on the mortgage rate and the price of the home, and forget about the other expenses that could be more a month than their mortgage,\u201d Kori Sassower, principal agent of The Kori Sassower Team at Compass, told Fortune. <\/em>Sassower is dually licensed in New York and Connecticut.\u00a0<\/p>\n

Taxes are the biggest of those variables, she said, and they can vary greatly from one town, village, or city to the next. But the cost that catches buyers off guard most is maintenance, which can include seasonal HVAC servicing, pest control, tree trimming, power washing, gutter cleaning, and stone repointing. Property taxes, in her experience, are \u201cthe number 1 driver that makes people sell their homes.\u201d<\/p>\n

For condo buyers, monthly association fees are another expense that can increase over time, Miltiadis Kastanis, a Miami-based real estate agent with Compass, told Fortune<\/em>.<\/p>\n

\u201cGood advisors prepare buyers for these costs upfront, but there\u2019s always a learning curve once someone becomes a homeowner because the true cost of ownership extends well beyond the monthly mortgage payment,\u201d Kastanis said.<\/p>\n

The hidden costs of homeownership<\/h3>\n

The hidden costs of owning a single-family home\u2014property taxes, insurance, utilities, internet, and maintenance\u2014now cost more than $21,000 per year nationally, according to Bankrate\u2019s 2025 study. Maintenance alone accounts for $8,808 of that, the single largest piece.\u00a0<\/p>\n

The most common regret among homeowners who had one was that upkeep and other hidden costs ran more expensive than they\u2019d expected, according to the Bankrate survey.\u00a0<\/p>\n

And while Michelle Griffith, a New York City-based real estate agent with Douglas Elliman, said NYC buyers are generally more aware of property taxes and other monthly costs, what tends to surprise them more are less obvious expenses like assessments, maintenance fees, furnishings, and the costs of maintaining a larger residence.<\/p>\n

\u201cBuyers relocating from rentals also underestimate how quickly everyday ownership expenses add up, particularly in luxury buildings where the expectation is to maintain a certain standard of living,\u201d she told Fortune<\/em>.\u00a0<\/p>\n

Insurance comes with its own separate shock. The average annual home insurance premium jumped 12% in 2025 and is on track to rise another 4%, to about $3,057, by the end of 2026, according to Insurify. Premiums have climbed 46% since 2021\u2014roughly three times the pace of inflation. The pain is concentrated in disaster-exposed states: Florida\u2019s typical premium is approaching $8,500, and California is expected to see the steepest increases in 2026 following the Los Angeles wildfires.<\/p>\n

So for a generation that already waited longer and saved harder to buy a home, the down payment and the rate get a buyer through the door. Everything after closing determines whether they can afford to stay.<\/p>\n

\u201cRecurring expenses may not make a home unaffordable on paper, but they can meaningfully impact a homeowner\u2019s monthly budget and lifestyle,\u201d Kastanis said.<\/p>\n<\/div>\n
