These Global Cities Show the Highest Real Estate Bubble Risk

Housing bubbles are a tricky phenomenon. As a market gathers steam and prices increase, it remains a matter of debate whether that market is overvalued and flooded with speculation, or it’s simply experiencing robust demand.

Of course, once a bubble bursts, it’s all obvious in hindsight.

One common red flag is when prices decouple from local incomes and rents. As well, imbalances in the real economy, such as excessive construction activity and lending can signal a bubble in the making.

The map above, based on data from the Real Estate Bubble Index by UBS, examines 25 global cities, scoring them based on their bubble risk.

Overinflated Markets

In the 2022 edition of the Real Estate Bubble Index, nine of the cities covered were classified as having extreme bubble risk (1.5 or higher score).

Canada’s largest city finds itself at the top of a ranking no city wants to end up on. Toronto’s home prices have been rising steadily for years now, and many, including UBS, believe that the city is now firmly in bubble territory.

Vancouver also finds itself in a similar position. Both Canadian cities have a high quality of life and have thriving tech industries.

Notably, none of the U.S. cities analyzed find themselves in the most extreme bubble risk category. The closest scoring U.S. city was Miami, which sits firmly in overvalued territory (0.5-1.5 range) with a score of 1.39.

Examining the Trends

In recent years, low interest rates helped push home prices and incomes further apart.

For cities in the bubble risk zone, prices have climbed by an average of 60% in inflation-adjusted terms over the past decade, while rents and real incomes increased by just 12%. And, while COVID-19 briefly put a dent in urban demand, rents in the cities analyzed rose at around the same pace as pre-pandemic times.

As a result, all but three of the cities saw positive price growth over the past year from a nominal price perspective:

U.S. cities occupy a number of spots at the top of this chart. Miami, in particular, is seeing strong internal migration patterns, as well as renewed interest from foreign investors.

Hong Kong experienced the biggest one-year nominal drop of all the cities analyzed. The report notes that since around 2019 Hong Kong “has broadly stagnated as the lack of affordability, economic woes, and pandemic restrictions all took a major toll on demand.”

Prices can’t rise forever. According to UBS, most cities with high valuations, price corrections have already begun, or could be right around the corner.

This is the Salary You Need to Buy a Home in 50 U.S. Cities

Depending on where you live, owning a home may seem like a far off dream or it could be fairly realistic. In New York City, for example, a person needs to be making at least six figures to buy a home, but in Cleveland you could do it with just over $45,000 a year.

This visual, using data from Home Sweet Home, maps out the annual salary you’d need for home ownership in 50 different U.S. cities.

Note: The map above refers to entire metro areas and uses Q1 2022 data on median home prices. The necessary salary was calculated by the source, looking at the base cost of principal, interest, property tax, and homeowner’s insurance.

Home Ownership Across the U.S.

San Jose is by far the most expensive city when it comes to purchasing a home. A person would need to earn over $330,000 annually to pay off the mortgage at a monthly rate of $7,718.

Here’s a closer look at the numbers:

Perhaps surprisingly, Boston residents need slightly higher earnings than New Yorkers to buy a home. The same is also true in Seattle and Los Angeles. Meanwhile, some of the cheapest cities to start buying up real estate in are Oklahoma City and Cleveland.

As of April, the rate of home ownership in the U.S. is 65%. This number represents the share of homes that are occupied by the owner, rather than rented out or vacant.

The American Dream Home

As of the time of this data (Q1 2022), the national yearly fixed mortgage rate sat at 4% and median home price at $368,200. This put the salary needed to buy a home at almost $76,000⁠—the median national household income falls almost $9,000 below that.

But what kind of homes are people looking to purchase? Depending on where you live the type of home and square footage you can get will be very different.

In New York City, for example, there are fairly few stand-alone, single-family houses in the traditional sense⁠—only around 4,000 are ever on the market. People in the Big Apple tend to buy condominiums or multi-family units.

Additionally, if you’re looking for luxury, not even seven figures will get you much in the big cities. In Miami, a million dollars will only buy you 833 square feet of prime real estate.

One thing is for sure: the typical American dream home of the big house with a yard and white picket fence is more attainable in smaller metro areas with ample suburbs.

Buying vs. Renting

The U.S. median household income is $67,500, meaning that today the typical family could only afford a home in about 15 of the 50 metro areas highlighted above, including New Orleans, Buffalo, and Indianapolis.

With the income gap widening in the U.S., the rental market remains a more attractive option for many, especially as prices are finally tapering off. The national median rent price was down nearly 3% from June to July for two-bedroom apartments.

At the end of the day, buying a home can be an important investment and may provide a sense of security, but it will be much easier to do in certain types of cities.
