Home Value Comparison Across U.S. Cities: What the Gaps Actually Mean

It's easy to look at two median home value figures — say, $280,000 in one city and $520,000 in another — and treat the $240,000 gap as the whole story. It isn't. That gap means something very different depending on what local incomes look like in each place, and skipping that context is the most common mistake in home value comparisons.

Normalize by income before comparing across cities

Divide each city's median home value by its median household income to get a home-value-to-income multiple. A $280,000 home value against a $70,000 median income is a 4x multiple; a $520,000 home value against a $140,000 median income is a 3.7x multiple — nearly identical affordability despite the large raw dollar gap. Comparing the multiples, not the raw dollar figures, is the fair way to judge relative affordability across cities with different income levels.

Home value doesn't capture ongoing ownership cost

Two cities with identical home-value-to-income multiples can still have very different total ownership costs once property tax rates and insurance premiums are factored in. Property tax rates vary enormously by state — from under 0.3% of assessed value annually in some states to over 2% in others — and that gap compounds every year you own the home. Home value comparisons are a starting point, not the full financial picture.

• Check the home-value-to-income multiple, not just the raw dollar figure.
• Check the state's typical property tax rate — it varies more than most buyers expect.
• Check homeowners insurance trends in the area, especially in regions with elevated climate risk.

Look at the trend, not just the snapshot

A current home value comparison is a single frame from a moving picture. Compare the current ACS5 release to the prior year's release for both cities to see whether the gap is widening, narrowing, or stable — that direction often matters more for a buying decision than the current-year snapshot alone, particularly if you're weighing a market that looks affordable today but is appreciating quickly.
