Study Reveals Effects of the ‘Hidden Costs of Homeownership’
According to a recent Zillow and Thumbtack analysis, the average American homeowner incurs annual expenses of $16,566, equivalent to approximately $1,380 monthly, encompassing maintenance, property taxes, and insurance in addition to mortgage obligations. This figure represents an estimated 3% increase compared to the previous year.
The following breakdown illustrates how these ancillary costs are distributed for the typical American homeowner:
- Maintenance: $11,171 a year, about two-thirds of the total
- Property taxes: $3,129 a year (estimated)
- Homeowners insurance: $2,266 a year (estimated)
Insurance costs have escalated by 54% over the past five years, substantially exceeding the growth rates of maintenance expenses (32%) and property taxes (19%). In major metropolitan areas including Houston, Phoenix, Denver, and Nashville, homeowners currently allocate greater financial resources toward insurance premiums than toward property tax obligations.
The scope of these ancillary expenses varies considerably by location, ranging from $14,187 annually in Phoenix to $25,111 in New York. Across all metropolitan areas examined, maintenance represents the predominant expense category.
Numerical homeowners prioritize the acquisition of residential property while underestimating the operational expenses associated with homeownership. These recurring financial obligations substantially contribute to the broader affordability challenges inherent in property ownership.

Insurance Premiums On the Rise
Throughout the preceding five-year period, insurance premiums have experienced a 54% increase, substantially outpacing the 32% rise in maintenance costs and the 19% increase in property taxes. This disproportionate growth is fundamentally altering the financial landscape across numerous major metropolitan regions throughout the nation. In Houston, Phoenix, Denver, and Nashville, TN, homeowners now allocate greater annual expenditures toward insurance premiums than toward property tax obligations.
Premium escalations of at least 50% over the five-year interval have occurred in 19 of the 30 metropolitan areas examined. The most pronounced increases are documented in Dallas (75%), Tampa (71%), Denver (70%), and Houston (69%). Miami residents bear the highest insurance burden, with annual premiums approaching $5,000, representing a 62% increase over five years. Six metropolitan areas have now surpassed the $3,000 annual threshold: Miami, Dallas, Houston, Tampa, FL, Orlando, FL, and Denver.

Maintenance represents the most substantial concealed expense across all metro areas examined, exceeding $12,000 in both Seattle, WA ($12,594), and Boston ($12,486).
Los Angeles experienced the most pronounced year-over-year escalation in maintenance expenditures, reaching 27%. This surge was predominantly attributable to continuous wildfire restoration initiatives, amplified demand for residential service provisions, and heightened compensation expenses for labor.
The metro areas with the most substantial concealed expenses are New York ($25,111), San Francisco ($24,383), Boston ($22,096), and Seattle ($21,354). Even Phoenix, which represents the most economical metropolitan region examined, experiences annual hidden costs of $14,187. During the five-year period, hidden costs demonstrated the greatest growth in Pittsburgh (54.8%), Tampa (44.4%), Miami (42.8%), and Los Angeles (42.5%). New York, despite already maintaining the highest cost structure, experienced the most modest increase at 13.8%.
