The Seattle area has now led the nation in home-price increases for more than a year — the longest streak in the region’s history. Just to keep up with those rising prices, would-be buyers needed an $11,000 pay raise in the past year to afford the typical mortgage.

Households now need a record $93,400 annual income to afford monthly payments on the median house in the Seattle metro area, according to a quarterly report from HSH.com, a mortgage and consumer loan information company.

That figure is up from about $82,000 a year ago — a level that already exceeded the region’s actual median household income of $78,600 last year.

But even that income number understates the true cost for a lot of buyers, since it assumes a 20 percent down payment, which most people don’t do. If you put 10 percent down, which is closer to the regional average, the income needed to afford typical monthly home payments jumps to nearly $110,000.

That income represents the average needed over a broad area from Tacoma to Snohomish, so it’ll get you a home you can afford in a place like Renton or Burien. If you’re looking for a home in the city of Seattle, the income needed to afford monthly payments on the typical house would exceed $140,000. In Bellevue and other pricey parts of the Eastside, it tops $170,000.

The salary needed to buy a home here is seventh-highest in the country among metro areas, behind San Jose, San Francisco, San Diego, Los Angeles, New York and Boston.

These calculations take into account all home payment expenses, like interest and taxes, and assume you spend 28 percent of your household income on your home payments.

Of course, this all also depends on your ability to afford the down payment, which is often the highest barrier to home ownership, especially for first-time buyers.

The typical down payment across the region is now $58,000, according to Attom Data Solutions, which tracks home purchases nationwide. In pricey submarkets in Seattle and the Eastside, most down payments now top $100,000. Both figures are up several thousand dollars from last year.

Add it all up and even responsible savers earning middle-class incomes are watching the housing market zoom faster than they can keep up with.

The monthly Case-Shiller home price index, released Tuesday, showed single-family home prices across the Puget Sound region rose 12.9 percent in September compared with a year earlier, the biggest increase in the country. Las Vegas was second, at 9 percent.

Seattle has had the nation’s hottest housing market for 13 straight months. That’s never happened before. Seattle led the nation in price increases for 12 months in a row right before the housing bubble popped a decade ago.

The market in Seattle has actually started to cool just a bit after peaking two months ago at 13.5 percent year-over-year growth. That runs counter to a national trend, where 16 of the other 19 regions tracked by Case-Shiller are seeing price growth accelerate.

Home prices were up 6.2 percent nationally in September, the biggest gain in more than three years. And yet costs in Seattle grew more than twice as fast as the U.S. average.

Compared with just a month prior, prices in Seattle actually went down 0.3 percent, the biggest drop in nearly three years and the largest decrease in the country. Still, home costs often dip here this time of year. When adjusted for normal seasonal changes, prices were still up half a percent from a month before, just shy of the national rate.

David Blitzer, managing director and chairman of the S&P Dow Jones group that puts out the Case-Shiller data, noted most economic indicators nationally — like low unemployment, cheap mortgage rates and rising rents — suggest home prices will continue to rise across the country.

“One dark cloud for housing is affordability — rising prices mean that some people will be squeezed out of the market,” Blitzer said in a statement.

As always, Seattle homebuyers can take some solace in knowing at least they’re not in California.

The salary needed to afford the median home in the San Jose area is $216,000, according to HSH.com. It’s $171,000 in the San Francisco region, and about $115,000 in both San Diego and Los Angeles.

Nationally, the benchmark salary required to afford a home is about $55,000.
