Understanding the Housing Affordability Crisis in Today’s Housing Market

January 20, 2026 / 19:40

This episode discusses the affordability crisis in the residential housing market, featuring insights from Ben Keys, a professor of real estate at the Wharton School. Key topics include the imbalance of supply and demand, mortgage rates, and potential solutions for improving housing affordability.

Ben Keys highlights that many households are struggling with high housing costs, whether through rent or mortgage payments. He emphasizes the need for more affordable housing units in desirable locations and discusses a recent piece he co-authored outlining solutions to this crisis.

The conversation touches on the impact of rising mortgage rates and the shortage of properties available for first-time buyers. Keys notes that the construction of starter homes has diminished, making it challenging for new buyers to enter the market.

Keys also addresses the role of government policies in addressing housing affordability, cautioning that demand-side measures might inadvertently raise prices rather than alleviate the crisis. He advocates for policies that stimulate supply and facilitate new construction.

Finally, the episode examines the commercial real estate sector's response to changing work patterns post-pandemic, including office-to-residential conversions and the effect of rising insurance costs on housing prices.

TLDR

00:00:00
Yeah. Well, we're in an affordability crisis when it comes to uh to the residential housing market. Um many
00:00:07
households are paying an extraordinary fraction of their income towards housing expenses, whether that's rents or or
00:00:14
whether that's their their mortgage uh their mortgage payments. And um in a piece I wrote for the Aspen Economic
00:00:20
Strategy Group with Vincent Raina um that came out in November, we outlined a list of potential solutions for dealing
00:00:26
with affordability. Um, but ultimately it comes down to an imbalance in supply and demand. Uh, we simply don't have
00:00:32
enough uh affordable housing units in the cities where people want to live. Welcome to the Ripple Effect, a podcast
00:00:39
that takes you on a journey [music] through the minds of Wharton faculty. I'm your host, Dan Looney, and in each
00:00:44
episode, we'll be diving deep into the inspiration behind the groundbreaking
00:00:48
[music] research that Wharton professors have conducted and exploring how their findings resonate with the world today.
00:00:56
We have seen the real estate market have quite the up and down ride the last few
00:01:01
years. Home prices soared of course during the time of the pandemic and haven't lost a whole lot since.
00:01:07
Meanwhile, the commercial market has had to deal with the work from home dynamic
00:01:11
change how some companies think about their real estate footprint. So, what lies in the sector ahead? Pleasure to be
00:01:17
joined [music] by Ben Keys, professor of real estate here at the Wharton School.
00:01:21
Ben, great to catch up with you. How are you, sir? >> I'm doing well. Thanks for having me,
00:01:25
Dan. Happy New Year. >> Happy New Year to you as well. It's interesting when you think about this
00:01:30
industry right now, the word that seemingly comes up on so many different interviews in so many different places
00:01:36
is seeing stability. Stability being that key word it seems like for 2026. Well, I think that's right. And and it's
00:01:44
stable in the sense that we're not expecting big swings in in house prices, especially in the residential side of of
00:01:51
the market. This is a market that is struggling on a number of different fronts. And I'm not sure if it's
00:01:56
stability or or stasis or if it's stuck. Um, but all of those things uh ultimately lead to a similar pattern
00:02:03
where we're going to expect national house prices to be relatively flat over
00:02:08
the coming year. And those national house prices being flat are going to sort of hide a lot of interesting
00:02:14
variation across the country. All right. So, we normally talk commercial and residential. Let me start with
00:02:20
residential. Uh mortgage rates have come down a little bit. They're still higher
00:02:24
than what we saw, you know, during the time of the pandemic. Uh we still have what's perceived to be a a fairly
00:02:30
important shortage of properties. Uh these seem to be like two of the biggest issues out there right now. Yeah. Well,
00:02:36
we're in an affordability crisis when it comes to uh to the residential housing
00:02:41
market. Um, many households are paying an extraordinary fraction of their income towards housing expenses, whether
00:02:48
that's rents or or whether that's their their mortgage uh their mortgage
00:02:52
payments. And um in a piece I wrote for the Aspen Economic Strategy Group with Vincent Raina um that came out in
00:02:58
November, we outlined a list of potential solutions for dealing with affordability. Um but ultimately it
00:03:04
comes down to an imbalance in supply and demand. uh we simply don't have enough
00:03:09
uh affordable housing units in the cities where people want to live. >> What are some of those ideas that you
00:03:14
think are going to be important moving forward? >> Well, I think there are a lot of
00:03:17
different proposals on the table. Some of those we're seeing from the administration just this week, sort of
00:03:23
policy by tweet. Uh but if you if you think a little bit more substantively about about the challenges, it is really
00:03:30
about supply. Um and uh and sometimes uh you know there are there are folks in the in the housing market that refuse to
00:03:37
believe in the dynamics of supply and demand and the ways in which they play out. But ultimately affordability in the
00:03:43
housing market is is is a function of supply and we need to make it easier to build. Um we need to ensure that
00:03:49
construction financing is available um through the through the interest rate cycle and and broader business cycle. Um
00:03:57
we need to do more to expand the the housing safety net. Um and I think we need to make home ownership a priority
00:04:03
when it comes to um the challenges that um first-time buyers face in competing with uh with investors. So one of the
00:04:11
things that has been a question in my mind for a long time is if you go back you know 60 70 years uh a lot of that
00:04:20
affordability was assisted by the starter home. And it seems like we've done away with the starter home for the
00:04:26
most part. you know that that property that you're just talking about that first property that somebody's looking
00:04:31
to buy gets them indoor to home ownership and then they can live in that house for maybe 10 years whatever and
00:04:38
build up to that next house. Now it seems like everything is $400 $500,000 and above and that's hard for a lot of
00:04:46
people to consider to be a starter home. >> Absolutely. That first rung on on the
00:04:51
housing ladder uh that you know gets your foot in the door to home ownership. It gives you an opportunity to build
00:04:57
some equity and it also gives you a chance to access a neighborhood that you might not otherwise have been able to
00:05:01
access. When it comes to school quality, when it comes to safety, when it comes to some other amenities, those are
00:05:07
harder and harder to find. We are seeing a small decline in the size of new homes
00:05:12
being built. So, new homes are shrinking just a little bit on average. But that said, I think your point is is a good
00:05:18
one, which is um that the that most affordable tier of of housing is not what's being built. And a lot of that is
00:05:25
a function of the high fixed costs of construction. It's difficult for builders to get uh approved. Um so to
00:05:32
get permits um and zoning challenges, something we've discussed for a long time is a big barrier. When you raise
00:05:38
those fixed costs, it means there's a higher hurdle to construction. We've
00:05:42
also seen construction costs rise sharply um really over the last 10 years. um you know house uh con house
00:05:48
housing construction costs are up about 60%. Over the last 10 years and that's a
00:05:52
function of both materials, labor, land and everything in between. And now you add financing costs with high interest
00:05:59
rates. And all of those things point to developers choosing to build at the high
00:06:02
end rather than the low end. Well, you mentioned uh the uh policy by tweet. Uh there are obviously a couple of things
00:06:11
in the most recent period that we heard from the administration. uh one being uh
00:06:16
that you know people that are connected to the president buying uh mortgage back
00:06:21
securities to maybe help uh lower rates, but the other thing was that President Trump brought up was corporate ownership
00:06:29
in single family homes and trying to maybe ease that out a little bit. I I don't know where both of those
00:06:36
components live. I don't know if you wanted to speak about either one of those, but the government seemingly is
00:06:42
going to play a role in trying to alleviate some of these issues, isn't it? >> I I think that's right. What's clear is
00:06:48
that the the problem has been diagnosed by the administration that we have an affordability problem. You know, maybe
00:06:54
maybe the administration read my op-ed in the Hill this past week uh with my colleague Vincent Raina on on improving
00:07:01
housing affordability. Um but they are throwing some ideas uh at the wall and seeing what sticks. The worry I is that
00:07:09
a number of these these ideas are going to stimulate demand rather than supply. And what that means in the housing
00:07:16
market is that's going to bid up prices. And so if we think about things like the
00:07:21
the 50-year mortgage or um you know buying mortgage back securities to try to drive down the mortgage interest rate
00:07:27
that is going to make um you know housing purchasing more accessible for those people on the margin who are you
00:07:33
know feeling crowded out because of high interest rates. But at the same time there's going to be more of them bidding
00:07:39
bidding for a scarce number of houses. And so there's going to be a portion of
00:07:44
that that's going to be captured by the existing owners in the form of higher
00:07:48
prices. It's hard to know exactly how how that all plays out, but I think, you
00:07:53
know, if we're looking at the the spectrum of potential policy responses, I think doing things that are largely on
00:07:59
the demand side are probably going to have unintended consequences. I'm much
00:08:03
more excited with with policies that are going to stimulate supply. And some of those are really uh when it comes down
00:08:10
to it about building new uh new housing, new construction, new units. >> But the the administration's proposal to
00:08:16
to squeeze uh institutional investors out of the market is another you know potentially very controversial and you
00:08:24
know potentially illegal uh proposal uh when it comes to thinking about um about
00:08:29
solutions to get people into home ownership. If you think about the large institutional investors in the US, those
00:08:34
that own, you know, a thousand uh homes or more, they represent only 1% of the US housing stock. And so on the margin
00:08:43
at that scale, it's just not going to move the needle for the affordability issues in the country. But as we go
00:08:49
further down and we think about the overall investor share in the market, it is on the order of 10% of all single
00:08:55
family homes in the country are owned by investors. And so, you know, I think there are things that can be done
00:09:00
through the tax code, um, through credit markets that that could, um, reduce the
00:09:05
benefits of ownership for investors and and steer those more towards, um, owner occupied residences. But I think, you
00:09:12
know, you know, fiat by tweet is certainly not going to get it done. >> And and we need to do something that
00:09:18
that's far more um, thoughtful and um, and resilient to um, to to potential challenges in the court.
00:09:25
>> What about the rate lock component? And that's something that we've talked about
00:09:28
for several years now. I mean, when you, you know, got into the early days of the
00:09:33
pandemic, so many people refinanced at 2 and 3/4, 3%, three and and a quarter% on
00:09:39
their existing home. That allowed them to open up and and do home projects. And there's just not a want or a need for
00:09:48
many people to move because of that. And that's the component that I I'm you know
00:09:54
from a historical perspective I don't think we had prior to the pandemic. You
00:09:57
can correct me if I'm wrong in that, but it it's a dynamic we're going to have in
00:10:01
this mix for quite some time. It it is and and it's something we've we've been
00:10:06
talking about for years now and will continue to talk about for years because over 50% of all outstanding mortgages in
00:10:11
the US have interest rates below 4%. And so when we're talking about doing things
00:10:17
to the mortgage back securities market that might move interest rates by 25 basis points, you know, from a little
00:10:23
bit above 6% to a little bit below 6%. The majority of mortgages are below four and and most of those people are going
00:10:30
to sit on those mortgages. um that is a you know one of the the the strongest performing um assets in their portfolio
00:10:38
is is a below market mortgage and that induces people to stay in their homes longer than they otherwise would. I
00:10:45
don't think we've seen this dynamic uh play out in really modern mortgage
00:10:49
history in the US with this degree of lock in and I and I think what that ultimately leads to is many fewer homes
00:10:57
on the market. it leads to to many fewer transactions and and it leads to these frictions when it comes to um people
00:11:03
finding where they want to live. I think one more underappreciated piece of this
00:11:07
is you know co really acted as a type of musical chairs in the housing market. There was a big opportunity where the
00:11:15
music was playing interest rates were low and people reoptimized and a lot of that reoptimization was accelerated
00:11:21
retirement or it was accelerated suburbanization. So people with young families moving to the suburbs, well the
00:11:27
music stopped, interest rates uh shot back up and now those people are happy where they are. And so, you know, I
00:11:33
think that that pulled a lot of transactions forward uh in time as well. And all of that leads to a more
00:11:38
depressed housing market when it comes to transaction volume and when it comes to the availability of properties. I I
00:11:44
mentioned the the uh the commercial real estate sector and let's spend some time
00:11:49
on that right now. Uh this obviously an industry that has been impacted by the pandemic as well because of the dynamics
00:11:56
of how companies have thought about their footprint. Uh employees working from home more often. Uh companies
00:12:03
reassessing just how much real estate they want to have in the mix and that's
00:12:07
leaving a lot of uh you know main street shops in some cases open and not being used. Yeah. I mean the just like with
00:12:19
with the residential side of the market, this has been a gradual process. I think
00:12:23
in some ways the financial crisis in 2008 sort of warped our brains into thinking that housing and real estate
00:12:28
markets respond very rapidly um to changing conditions and in fact they usually respond very slowly. Mo most
00:12:35
office uh leases are 10 years or longer. Um and so firms are only very gradually
00:12:41
reassessing uh how much space they want to use. Um but we are seeing a big uptick in in office um to residential
00:12:48
conversions and uh you know this year um we're going to see the Flat Iron Building in New York City um probably
00:12:55
finish their conversion process um into into residential units and that's kind
00:12:59
of the um you know the the the the leading uh I would say the leading example of a very famous building uh
00:13:07
where this conversion is happening. And I think we are seeing it um play out in cities across the country where
00:13:13
downtowns um emptied out of many of their office workers and now um there's a desperate effort to to bring foot
00:13:19
traffic back to the city and some buildings are much more easy to to repurpose than than others. I think that
00:13:25
it also as you alluded to has these knock-on effects for retail u depending on the foot traffic in some of these
00:13:31
downtowns and some of the corridors have bounced back very quickly and others continue to struggle and that's really a
00:13:37
function of the the industries and the dynamics city by city. One of the other hopes I guess was the fact that uh the
00:13:43
ad current administration talked a lot about uh the repatriation of uh companies coming into the US uh taking
00:13:51
over facilities, taking over factories and building out property from there. Uh that will probably happen to a degree,
00:13:59
but would it happen enough where you're going to have a significant impact on
00:14:03
the commercial real estate market as a whole? I I wouldn't think so given the
00:14:07
the dynamics of work from home across industries, right? The industries that that I think they have in mind are much
00:14:13
more about manufacturing and um and really about controlling supply chains. I think the the kinds of work from home
00:14:21
dynamics is much more about um about office workers. Um and it's not office jobs that are that are in the discussion
00:14:27
when it comes to to repatriation. So so I think those are you know slightly uh on two different tracks. I think you
00:14:34
know office jobs you know we have seen firms kind of settling into a work from home that's uh that's some sort of in
00:14:42
between uh model where you're in the office two three maybe four days a week.
00:14:47
>> Yeah. >> And in that case if you're using you know your same offices three or four
00:14:51
days a week you probably don't need to downsize all that much on on your office
00:14:56
space. But there may be some ways in which you can use that space more flexibly or more creatively. and we're
00:15:01
seeing firms uh making agreements that that allow them to do that with with more flexible agreements. Two final
00:15:08
things I wanted to bring up. First one, rents. I know you have followed rents closely. It's been an important topic
00:15:13
for you. Uh we've seen rents come down. That's obviously going to be a good
00:15:18
thing whether it is uh residential or commercial moving forward. Where are we in terms of rents right now?
00:15:26
Yeah, I think um good thing for the renters uh to see the rents coming down. I I think we're seeing um continue to
00:15:33
increase supply uh of uh rental units in in many markets and and that's delivering on lower rents. We're seeing
00:15:40
increases in concessions from landlords. So that means like uh offering free rent
00:15:46
or um or some other kinds of perks to try to get people in the door. We're seeing big gaps between um the existing
00:15:53
rents that that are being paid and the rents for for new renters in in a lot of markets. There's a big wedge between
00:16:00
those. This is an opportunity where if you're a renter right now, it pays to
00:16:03
shop around >> and see what's out there because if you've been in the same place for three
00:16:07
or four years, >> um chances are that that the new renters in your building might be paying quite a
00:16:12
bit less than than you are. So in the cities where where we've seen an uptick
00:16:17
in construction especially since co we are seeing rents soften that in other places like in in Manhattan you know
00:16:24
rents remain astronomical. So it it is a tale of of different markets for sure. What about the insurance industry and
00:16:32
some of the concerns that they have had you know about some of the building areas about uh uh climate change a
00:16:38
variety of different concerns. Insurance costs have obviously been a big problem
00:16:42
for many people. >> Yeah. Insurance has been a big focus of my research over the last couple of
00:16:47
years. We're seeing large increases in homeowners insurance over the last few
00:16:51
years. And if anything in the commercial side, insurance has increased dramatically faster. It's just a much
00:16:56
less regulated market. And and what we're seeing in this latest wave of research is that this is having an
00:17:02
effect on house prices. is that the areas that have seen the sharpest increases in insurance, which tend to be
00:17:08
those that are most prone to disaster risk, whether that's wildfires, hurricanes, or severe storms and and
00:17:14
hail. Um those are areas where we are seeing house prices respond. Now, these are areas that have in general already
00:17:21
seen house prices rise quite dramatically uh over the co housing boom, but we estimate that they would
00:17:27
have risen, you know, maybe $20,000 more had it not been for uh for rising insurance costs. So, these insurance
00:17:34
costs are are really a pocketbook issue for for households uh at the moment and it is affecting asset values in a very
00:17:40
direct way. Let me finally touch on this. It's seemingly the topic that everybody talks about these days. Uh,
00:17:47
are you seeing a a significant impact from AI in the real estate market right now?
00:17:53
>> I think we're still in the early innings when it comes to AI in real estate and
00:17:57
some of that is uh a question of of organizing often uh messy and complicated data sets whether that comes
00:18:04
from um you know if you think about a multifamily uh owner who has information on rents and vacancies also information
00:18:12
on expenses also interacts with their with their tenants. I think we're seeing
00:18:16
AI at the sort of entering in where you'd expect to the lowest hanging fruit. So things like chat bots to to
00:18:23
manage maintenance requests. I think that's kind of the early stages of this.
00:18:27
But when it comes to really building out the functionality of AI for real estate
00:18:32
investing, whether that comes to making portfolio decisions, um you know, purchase decisions, um or renovation
00:18:38
decisions or or um or exit decisions, I don't think we're there quite yet. Um, I
00:18:44
think there are some firms that are leading the charge, but it it's still very early stages when it comes to the
00:18:49
interplay between uh between AI and real estate. But, you know, I'm teaching a
00:18:53
course this this spring, starting next week, on real estate data analytics, uh, which which I think of as the, you know,
00:19:00
the the the precursor to um to really embedding AI into the systems when it comes to real estate investing.
00:19:06
>> Going to going to drag you kicking and screaming down that path, isn't it, Ben?
00:19:11
>> Far far from it. We love we love data over here. There you go, Ben. Great to
00:19:15
catch up with you again. Thanks very much. All the best. Look forward to talking to you throughout the year.
00:19:19
