Home Affordability In America's Largest Cities

Key Takeaways

• Affordability is about the relationship between home prices and local incomes, not price alone.
• The 28/36 rule is a common benchmark for how much house you can afford.
• Property taxes, insurance, and incomes vary widely between metros.
• Comparing cities fairly means weighing prices against local pay and total ownership costs.

What makes a home affordable?

Home affordability is widely misunderstood, because it's not really about the price of a house in isolation. A home is affordable relative to the income of the person buying it and the full cost of owning it. A $500,000 house can be perfectly affordable in a high-income city and completely out of reach in a low-income one. The price alone doesn't tell you.

The most useful way to think about affordability is the relationship between local home prices and local incomes. A city where the median home costs three times the median income is far more affordable than one where it costs ten times, even if the second city's absolute prices look more familiar. This price-to-income relationship is the heart of affordability.

Lenders and financial advisors use rules of thumb to translate this into a personal budget. The most common is the 28/36 rule^[1], which caps your housing costs and total debt as percentages of your income. It turns the abstract idea of affordability into a concrete number you can work with, how much house your income can actually support.

Affordability also depends on more than the mortgage. Property taxes, insurance, and other ownership costs vary enormously between cities and can make a nominally cheap home expensive to own, or a pricier one more affordable than its sticker price suggests. The sections below unpack the 28/36 rule, the reasons affordability differs so much between metros, and how to compare cities honestly. You can check your own numbers against that rule with our home affordability calculator.

The 28/36 rule in practice

The 28/36 rule is a widely used guideline for how much house you can afford. It has two parts: your housing costs should stay under 28% of your gross monthly income, and your total debt payments (housing plus car loans, student loans, and credit cards) should stay under 36%, the threshold lenders watch through your debt-to-income ratio. The two limits work together to keep your overall debt manageable.

Putting numbers to it makes it concrete. For a household earning $8,000 a month gross, the rule suggests keeping housing costs under about $2,240 (28%) and total debt payments under about $2,880 (36%). Those caps give you a target: the housing payment your income can comfortably support without stretching your finances too thin.

You can work backward from these caps to estimate the home price you can afford. Starting from the $2,240 housing budget and accounting for current interest rates, property taxes, and insurance, you can calculate the mortgage, and therefore the home price, that fits. This reverse calculation is exactly what affordability calculators do, translating your income into a realistic price range.

The 28/36 rule is a guideline, not an iron law, and your personal situation may warrant some flexibility. Someone with no other debt might stretch the housing portion, while someone with high expenses elsewhere should stay well under the caps. But as a starting point, the rule grounds the question of 'how much house?' in your actual income rather than wishful thinking.

Why affordability varies so much by city

The single biggest driver of affordability differences between cities is home prices, which vary dramatically across the country. Coastal metros like San Francisco, New York, Los Angeles, and Boston carry median home prices several times higher than many cities in the Midwest and South. The same house, figuratively speaking, can cost three or four times as much depending on the metro.

But prices don't tell the whole story, because local incomes vary too, and often in the same direction. High-cost cities frequently pay higher salaries, which partly offsets their steep prices. This is why the ratio of median home price to median income is a better affordability gauge than price alone: a pricey city with high pay can be more attainable than a cheaper one with low wages.

When you compare price-to-income ratios, the picture sharpens. Some expensive coastal metros have ratios so high that even good salaries can't keep pace with home prices, making them genuinely unaffordable. Others combine moderate prices with solid incomes, yielding far more reasonable ratios. The interplay between the two factors, not either one alone, determines real affordability.

Local economic conditions add further variation: job growth, the mix of industries, and housing supply all feed into both prices and incomes. A city building plenty of housing relative to demand will tend to be more affordable than one where supply is constrained and prices spiral. These dynamics are why affordability maps so unevenly across America's largest cities.

Property taxes and insurance

Beyond the mortgage itself, property taxes and insurance are major ownership costs that vary enormously by location, and they can flip a city's apparent affordability. Two homes at the same price can cost very different amounts to own if one sits in a high-property-tax state and the other in a low-tax one. These recurring costs belong in any honest affordability comparison.

Property tax rates differ widely from state to state and even between localities. A modestly priced home in a high-tax area can carry an annual tax bill that rivals a much pricier home elsewhere, adding hundreds of dollars to the monthly cost of ownership. Buyers who focus only on the purchase price can be blindsided by the ongoing tax burden in some markets.

Insurance costs vary just as much, driven largely by local risks. Homes in areas prone to hurricanes, wildfires, floods, or other hazards can carry steep insurance premiums, and in some high-risk markets, insurance has become a significant and rising share of the total cost of ownership. A 'cheap' home in a disaster-prone area may not be cheap to insure at all.

Because these costs are bundled into your monthly housing payment (often via escrow), they directly affect how the 28/36 rule plays out. A higher tax-and-insurance load means less of your housing budget is available for the mortgage, lowering the home price you can afford. Comparing cities fairly requires factoring in these costs, not just sticker prices and mortgage rates.

High-cost vs. affordable metros

Broadly, the least affordable large metros cluster along the coasts, where home prices have far outpaced incomes over the years. Cities like San Francisco, San Jose, New York, Los Angeles, and Boston routinely top the list of expensive markets, with price-to-income ratios that strain even well-paid households. In these metros, homeownership can require enormous incomes or substantial wealth.

Many of the most affordable large cities, by contrast, sit in the Midwest and South. Metros across these regions often combine moderate home prices with solid local incomes, producing far more reasonable price-to-income ratios. For buyers prioritizing affordability, these markets frequently offer a realistic path to homeownership that coastal cities don't.

But the broad regional pattern has important caveats. Adjusting for local incomes narrows some of the apparent gap, since high-cost cities often pay more. And property taxes and insurance can hit some 'affordable' markets hard: a low purchase price paired with high taxes or soaring insurance can erode the affordability advantage. The headline price ranking isn't the final word.

The practical lesson is that affordability rankings depend heavily on what you measure. Pure price rankings, price-to-income rankings, and total-cost-of-ownership rankings can each tell a somewhat different story about the same cities. Understanding which measure you're looking at (and ideally weighing several) gives a far more accurate picture than any single list of 'most' or 'least' affordable metros.

How to compare cities fairly

To compare home affordability across cities honestly, look beyond list prices to the relationship between prices and local incomes. The price-to-income ratio is the single most revealing metric, because it captures whether typical residents can actually afford typical homes. A city with high prices but proportionally high incomes may be more attainable than a cheaper city with low wages.

Next, factor in the full monthly cost of ownership, not just the mortgage. Add property taxes and insurance (which vary enormously by location) to the principal and interest to see the true cost of owning in each city. A home that looks affordable on price alone can become expensive once a high tax-and-insurance load is included, and vice versa.

It also helps to weigh that total monthly cost against typical local salaries using a framework like the 28/36 rule. Asking what income a city's median home requires, and how that compares with what the city actually pays, turns affordability from an abstract ranking into a concrete question of whether the math works for a real household there. Its more important than ever to find affordable housing as America experiences an affordability crisis.

Finally, remember the factors beyond housing that affect real affordability. Keep these comparison pitfalls in mind:

• Comparing prices without incomes: affordability is a ratio, not a number.
• Ignoring property taxes and insurance: they swing the true cost between cities.
• Forgetting the 28/36 guideline: it grounds 'how much house' in your actual income.
• Overlooking commute and other living costs: they affect real affordability too.

Frequently Asked Questions

What is the 28/36 rule?

A guideline that housing costs should stay under 28% of gross monthly income and total debt under 36%. It's a quick way to gauge how much home you can afford.

Why are some cities so much less affordable than others?

Mainly home prices relative to local incomes, plus differences in property taxes and insurance. Coastal metros tend to be priciest; many Midwest and South cities are more affordable.

Is a cheaper city always more affordable?

Not necessarily. Lower incomes or higher property taxes and insurance can make a 'cheap' city less affordable than a pricier one with strong salaries.

How do I compare home affordability between cities?

Look at price-to-income ratios and the full monthly cost (mortgage, taxes, and insurance) against typical local pay, not just listing prices.

What costs besides the mortgage affect affordability?

Property taxes and insurance are the big ones and vary widely by location. Commute costs and general cost of living also affect real affordability.
