Median age of housing by state and county

Using Census data, HouseMethod looked at the median age of homes across different geographies in the United States:

Age may just be a number, but when it comes to the age of a home, it can be an indicator of its style, features, or condition. It can even help tell a story about where it’s located. Home construction, especially in modern building, comes in waves in areas with new developments springing up as a city grows…

New York came in as the state with the oldest median home age in the U.S. at 63 years. Rhode Island was a few years younger at 60, followed closely by Massachusetts (59), Pennsylvania (57), and Connecticut (55). No surprise that the five states with the oldest median home age are all located in the northeast as they had some of the largest growth in early America. 

At the other end of the spectrum, the five states with the youngest median home age are Nevada (26), Arizona (30), Utah (31), Georgia (31), and North Carolina and South Carolina tied at 32 years old. Nevada has been the fastest-growing state for roughly five decades so it follows that the homes would be the newest. Likewise, the other ‘youngest’ states have seen large population increases and the housing being built to satisfy the demand…

The county with the oldest median home age in the U.S. is Clay County, Kansas. The county’s median year of structure build is 1941, bringing the county’s median home age to 79 years. The Sunshine State of Florida holds the ‘youngest’ county in the country, with Sumter County, Florida having a median home age of 17 years.

The median is helpful here: half of the homes were constructed before, half after. I do not know if the Census reports this data but it would also be interesting to know the 25th and 75th percentiles or other points along the data distribution. Are there also places that have more compressed or longer ranges of development?

Is it surprising that there a good number of older county medians in the center of country, roughly running from Texas to the Dakotas?

This reminds me of Dolores Hayden’s book Building Suburbia: Green Fields and Urban Growth, 1820-2000. She details waves of suburban development, dependent on factors like transportation technologies and ideas about what suburbs should be and include.

What happens to the housing in the locations with older housing overall? What percent ends up fixed up and restored or designated as part of a historic district? In contrast, what percent is undesirable and not brought into a more modern era?

The places in the United States with a housing surplus

A new analysis shows which metropolitan areas in the United States have a housing shortage or surplus:

A quick look at this map shows the biggest metro areas tend not to have a surplus while smaller regions have a higher likelihood of having a surplus. There is additional analysis showing at least a few metro areas that had a housing surplus in 2012 that did not in 2019.

While it is intriguing to see that some places have housing while others need it, the answer is not to have people in large numbers move from the housing shortage areas to those with a housing surplus. Both the rise of certain cities in recent years and the COVID-19 pandemic offered some hints of what this leads to: the effects of cities losing residents (if just temporarily) and rising housing prices in markets experiencing a lot more interested housing seekers. At the same time, as noted in the article, a national policy is difficult to imagine and/or enact.

Hopefully, by the time a similar time period passes and a new map is released, there are more metro areas with available housing.

Data on how higher housing prices are pushing more people to purchase fixer-uppers

As housing prices rise, one potential option for homebuyers is to purchase a home needing repairs or renovation. Here are some numbers on this option:

“When everyone else is looking for a move-in ready home, there’s less competition for the fixer-uppers,” said Daryl Fairweather, chief economist at Redfin Corp. “I would not advise it for the faint of heart, but there are a lot of people who are willing to take on that risk because there is such a high reward.”

In 2021, homes in need of renovation sold at a faster pace than the two prior years, according to data from Realtor.com. Fixer-upper sales jumped 13.4% from 2020 to 2021, while the dollar volume of those deals surged 40.8% from 2019 to 2021, reflecting the high growth in sale prices across the broader market. Plus, listings described as “fixer-upper” or using other related terms by agents increased by 8% in December from the previous year…

In a survey by housing research firm Zonda, 33% of respondents said they would buy a fixer-upper for their first or next home but “only if I got a great deal.” Meanwhile, 27% said they would “if the repairs are minor.” Just 20% responded with a “no thanks.”…

On average, fixer-uppers cost 13% less than their move-in ready counterparts, or are about $40,000 less than the typical U.S. home value, according to Zillow. But if that home needs $80,000 to make it livable, that’s not such a great deal, Pendleton said. She recommends that those fixing up homes add an extra 20% onto their budget as a cushion for the unforeseen. 

As the article notes, not everyone has an appetite, resources, or the skills for renovation. But, if the housing options are limited, this appears to be an increasingly attractive option for some. The data cited above suggests a small bump in people selling and buying such homes.

This is also interesting to consider from the other side: the sellers. If someone had a home that needed significant repair, this might be the time to not do those repairs and still get a good price. All those homes needing “TLC” or sold “as-is” now might not linger on the market for months.

More broadly, this hints at how much housing in the United States is eligible for repairs and renovation. The postwar suburban boom started roughly 70 years ago now. Those homes have already likely experienced a lot of repair and change and will undergo more in the upcoming decades. The McMansions of the 1990s and early 2000s will be the fixer-uppers of the future. And since Americans tend to like DIY projects and homeownership, we could be in for more decades of renovations.

Chicago as “the nation’s capital of deconversions” from condos to apartments

Henry Grabar suggests Chicago is ground zero for efforts to convert condos to apartments:

Stories like this make Chicago the perfect place to understand how condos usually meet their end—not in a pile of rubble, but in a buyout that leaves some owners feeling lucky and others feeling betrayed. Lauren Kerchill, the owner of a Gold Coast unit overlooking Lake Michigan, was a holdout when investors came to buy out her building. After fighting to toss her condo board, she told Crain’s Chicago Business she was called “petty,” “greedy,” and “uneducated.” She just didn’t think she could find another home like hers nearby. In the end, she didn’t have a choice. Her neighbors voted to sell her building, at 1400 Lake Shore Drive, for $107 million in 2019—another record, this time the most expensive deconversion in the country…

But there’s another side to the story, in which deconversion is the only way out for condo owners stuck in deteriorating properties. In June, the collapse of Champlain Towers South in Surfside, Florida, drew attention to the challenges that confront condo boards as they assess structural damage and raise money for repairs. Maintenance bills for the Great American Condo Boom of the ’70s and ’80s are starting to come due in areas like South Florida…

While states like Florida, California, and Hawaii saw tons of new condo construction in the decades after the concept was established in the 1960s, Chicago saw a different kind of boom: older buildings becoming condos. Fearing rent control, facing declining profits, or saddled with obsolete prewar commercial space, landlords in Chicago raced to sell off their units in the 1970s. Yuppies and middle-class workers gobbled up these starter apartments, which provided an easy and cheap entry point to homeownership.

Fifty years later, those buildings are among the oldest condominiums in the country. Owners who have not kept on top of maintenance, and even some who have, sometimes find themselves facing massive repair bills.

It would be interesting to read more about the specific aspects of Chicago’s history, real estate market, and local regulations that play into the the number of condo deconversions in Chicago.

More broadly, this gets at two larger housing issues:

  1. How do deconversions fit with a larger American promotion of homeownership? Condos offer opportunities to offer homeownership opportunities in settings where the single-family home is less possible. But, given market conditions right now, is there now increased interest in having more rental units?
  2. While aging and the associated expenses is an issue for condo buildings, it is also an issue for many more housing units in the United States. What happens to older homes and residences when there is limited interest in repairing them or redeveloping the property? In wealthier communities and desirable locations, there are often developers and individuals interested in rehabbing or rebuilding structures. Hence, teardowns or new residences in suburban downtowns. Elsewhere, replacing or changing housing is a more arduous task.

Looking to “produce, preserve, and retrofit” American homes for the future

What will happen to American homes in the coming homes, particularly all the suburban tract homes and McMansions? One path forward is to provide resources to fix up and improve existing homes. According to plans from the White House:

Photo by Rodolfo Quiru00f3s on Pexels.com

Build, preserve, and retrofit more than two million homes and commercial buildings, modernize our nation’s schools and child care facilities, and upgrade veterans’ hospitals and federal buildings. President Biden’s plan will create good jobs building, rehabilitating, and retrofitting affordable, accessible, energy efficient, and resilient housing, commercial buildings, schools, and child care facilities all over the country, while also vastly improving our nation’s federal facilities, especially those that serve veterans.

As housing ages, issues pop up. They need maintenance. Standards change regarding efficiency, local codes, and what residents desire. The community around houses and housing can change in terms of demographics and development, affecting the reputation of the neighborhood.

This plan emphasizes retrofitting homes, among other options. Energy efficiency is one reason as features like new windows, better furnaces and air conditioners, insulation, and more can cut down on energy use and utility bills. Retrofitting can also help maintain the appeal of homes; instead of falling into disrepair or failing to keep up with the times, retrofitting can spruce up houses that have been around for a while.

Some of this has been available through various means for a while. The concept does stand in contrast to another approach Americans have taken: just build new homes in sprawling suburbs or as teardowns and leave the older homes and their issues to others. Retrofitting single-family homes could be quite a project in the long-term with the emphasis on the United States on single-family homes in the suburbs. Does every suburban home require or deserve retrofitting at some point?

Questions a sociologist asks when seeing changes in the housing stock in their community

I try to pay attention to housing changes in the suburban community in which I live. Here are some questions I ask as I observe both existing and new homes:

  1. What existed here before this current residence?
  2. What motivated the property owners to tear down the existing home and build these homes (and in these particular styles)?
  3. How do existing and new homes interact with their surroundings?
  4. What does the inside of the home look and feel like? The outside provides some clues but interiors can be quite different from house to house.
  5. What happened at the community level (decisions, regulations, proposals, discussions, etc.) for these homes to exist in this form?
  6. In the long run, will these changes be viewed positively in the community or negatively?
  7. Who are the people who live in these homes (who is this housing for)? Are they the same or different kinds of people who are in the community?

We can measure features of old and new homes and look at the aggregate data. For example, we could try to look at the “average” home largely based on standardized traits. These figures are helpful but they also leave out other important traits of homes: what is their character? How are they experienced by the owners and the neighborhood and how do they shape social actors? How do they contribute to community life? What do they say about the priorities of the occupants and the community?

In sum, homes are not just part of the housing stock. Each house has the potential to shape and be shaped by people who interact with its material and symbolic presence. And when the housing changes, it can alter existing understandings.

Flipping houses stats – up then Great Recession then up then down again – and questions

How many houses have been flipped in the United States in the last fifteen years? Here are some of the stats:

In the first three months of 2020, 7.5% of homes sold in the United States were flipped, according to a June report from real estate research firm ATTOM Data Solutions. That’s the highest rate since 2006 and a jump from 6.3% at the end of 2019.

Home flipping rates had dropped drastically in 2007 and began to gradually recover in 2010. The number of flipped homes sold in a quarter peaked around 100,000 in 2005, and while it was on the rise in recent years, a decline began in the second quarter of 2019. In the first quarter of 2020, 53,705 single-family homes and condos were flipped, according to the report.

Profit margins have also dropped since 2019, hitting the lowest return-on-investment since 2011. After plummeting with the national economy between 2006 and 2008, profit margins on flipped homes grew at a steady rate until 2017. But since then, return-on-investment has been on a decline.

Still, it’s too soon to fully grasp how the coronavirus pandemic will impact the house flipping market through 2020 and beyond, ATTOM chief product officer Todd Teta said in a statement.

Flipping homes is by now a well-known process due to TV shows and personalities plus its spread throughout the United States. Yet, alongside other phenomena featured on HGTV and among certain groups (such as tiny houses), it can be hard to know how widespread a phenomena is.

Not surprisingly, these stats suggest flipping homes is connected to broader economic conditions: flipping increases when property values are high and repairs to a home can pay off in a sale. When times are tough and property values stagnate or even drop, there is less money to be made in flipping homes.

In the data above, it would be helpful to see how the national trends compare to patterns in particular places. Does flipping work in the hottest markets where prices are already high (limiting who can flip)? What about Rust Belt communities in good and bad times? Suburbs? Urban neighborhoods? I would guess there is a lot of variation across communities.

It is also worth considering what happens to the housing stock in places where flipping does or does not take place. If flipping happens, older housing stock gains new life. If it does not, do these homes simply keep sliding into disrepair?

Finally, this article starts with an example of a family involved in a flipping business but says very little about the role of small flipping businesses or more corporate operations. Even if flipping activity declines during tougher economic times, does it present opportunities for some to buy up properties to flip later? How do the profit margins differ across different kinds of flippers? Are smaller firms or family-owned flippers viewed more favorably by communities than corporate entities?

Competing claims: America has a shortage of housing versus it has plenty of housing (albeit overpriced or inaccessible)

Does the United States have lots of housing units or a shortage? The two sides of the argument:

  1. A few years ago, I had a conversation with a sociologist who studies housing. When I brought up the issue of not enough housing units in connection with a need for more affordable housing, they said the problem was not a lack of units. Rather, more of those units needed to be made available to the people who for a variety of reasons could not easily access them now.
  2. A recent opinion piece states the other side of the argument:

“Stephen, you’ve been proven right on housing, and I think you’re about to be proven even more right. The most important driver of home prices is supply and demand. And right now, there is a chronic undersupply of homes in America.

As I said, the 2008 bust turned a lot of folks off from investing in housing. It shattered the confidence of homebuilders, too. Census Bureau data shows an average of 1.5 million homes were built each year since 1959. Yet since 2009, just 900,000 homes have been built per year. In fact, fewer homes were built in the past decade than in any decade since the ‘50s!

We have a serious housing shortage in America today. It would take less than six months to sell every existing home on the market, as you can see here…

…In the past year or two, the first wave of young homebuyers came into the market. But every year for the next decade, tens of millions of Millennials will hit home-buying age.”

I could see a possibility where both prognosticators could be true: there are many dilapidated or older units that need to be updated and priced in ways that more people can access them and there is a relatively shortage of new homes that meet the demands and tastes of younger buyers.

But, this gets at some bigger questions about housing in the United States:

  1. How many older housing units can be renovated to today’s codes and standards? And who should pay for this?
  2. Should anyone be put in charge of or help set housing prices so that more housing units are within economic reach of more residents?
  3. Should developers and builders primarily focus on profit or do they also have a responsibility to communities (beyond paying a fee for affordable  housing or sprinkling in a few cheaper units)?
  4. Can housing be revitalized in areas without significantly changing the population composition or housing values or other ways that might significantly disrupt what current residents like about the location?

Is my 45 year old suburban home worth preserving?

I realized recently that my suburban home of nearly two years is 45 years old. While there are no major problems with the home, it made me think: how long could the house last? And, how much effort and money should be expended to keep it going?

The home has some nice features but I don’t think there is much that distinguishes it from millions of other suburban homes. Its architecture is bland if not McMansion like and the lot has a good location.

As the postwar housing stock ages, many homes like ours may face more issues and newer housing units in a variety of places provide new competition. Complicating matters is that many of these older suburban homes command a decent price. When located in more desirable communities, these dwellings will likely prove attractive for some time.

But, when will the tide turn? When will the repair costs become extensive? Are older suburban neighborhoods destined for teardowns or complete redevelopment, not just in the wealthiest areas? Will populations shift away from postwar suburban neighborhoods?

I have little idea of how many years I should predict my suburban home will stand. Twenty-five more years? Seventy-five? One hundred? The builders and developers of postwar suburbs probably spent little time considering what their neighborhoods of tract homes would look like in a century but we are not too far from that. Future generations will decide whether homes like mine are worth investing in or no longer the trouble.

Patterns across the ten metro areas with the most big homes

While the article I discussed yesterday did not provide a helpful definition of a McMansion, it did provide five trends regarding which metropolitan areas had the largest homes:

Supersize trend No. 1: Outdoorsy types need plenty of space

Supersize trend No. 2: Seeking space in the suburbs

Supersize trend No. 3: Southern cities are churning out jobs and big homes

Supersize trend No. 4: Big homes are all that’s left in tight Midwestern markets

Supersize trend No. 5: Tech hubs + deep pocked buyers = more McMansions available

And, like the McMansion definition, another important caveat:

And if it wasn’t for the fact that we limited our ranking to one housing market per state, Colorado and Utah would’ve had all five top metros.

And a third caveat: this is based on only homes that are on the market.

Even with these significant limitations, I wonder if an analysis could reveal some underlying patterns behind these noteworthy metropolitan areas:

  1. They have a growing population and thus a growing stock of larger, new homes, particularly in suburbs.
  2. They have relatively low housing prices paired with enough higher income jobs. (Seattle and Portland are the ones that stick out here but perhaps this is relative: those same buyers could find higher prices in the Bay Area, LA, Vancouver, etc.)
  3. These places have looser zoning restrictions on the whole that allows for more and/or quick construction. (I imagine there is some variation in these top 10 places. Portland and Bridgeport, for example, likely have some tight restrictions compared to an Indianopolis or Provo.)

This could be worth pursuing though the data needs to provide a more complete picture of the housing stock.
