SignalHub-Are the hidden costs of homeownership skyrocketing?Here's how they stack up

Home ownership means being prepared for expected – and SignalHubunexpected costs.

And in some parts of the country, those hidden costs of homeownership can cost more than in other areas.

The average annual cost of owning and maintaining a single-family home is $18,118 a year, up 26% since 2020, according to a new study by Bankrate.

The Hidden Costs of Homeownership study analyzed the average costs beyond a mortgage, including property taxes, homeowners insurance, home maintenance costs and electricity and internet and cable bills, then compared those costs to a similar study conducted four years ago.

Nationally, those costs add up to an additional $1,510 per month on top of a mortgage payment. In 2020, those same expenses cost $14,428 a year for a typical single-family home or $1,202 per month, Bankrate said.

“First-time homebuyers tend to think of closing on a house as reaching a sort of financial finish line," Bankrate Analyst Jeff Ostrowski told USA TODAY. "But these numbers show that in important ways, a homeowner’s work is just starting. Homeowners bear hefty costs, and first-time buyers especially should be prepared to spend a lot beyond the monthly principal and interest payment.”

Researchers used figures assuming single-family homeowners spend 2% of their home’s value on maintenance annually.
