What the Star Tribune got wrong about firms buying up single-family homes in the Twin Cities

The front page of the business section in the StarTribune for Sunday, December 5, 2021, prominently features an article headlined “Rental firms snap up metro houses,” or in the web version, “National investors are snapping up Twin Cities area houses to rent.” This topic relates to the streets.mn core values: the mix between owner-occupied and rental properties affects our communities’ ability to empower and include the vulnerable and marginalized. The type of entities that own rental properties also has an impact, whether they be local individuals or national corporations. Alas, the newspaper’s highly visible article is not a reliable guide to this topic.

This will be a long explanation of some of what’s wrong with the article focusing on what I see as the core of the piece, which is its presentation of the Minneapolis Fed’s data about property ownership. I’ll ignore the more context-setting stuff regarding the difficulties buyers are facing.

The property ownership data passed through three consecutive stages. First, county assessors’ offices in each of the seven counties accumulated it for reasons unrelated to this analysis. The fact that they had other purposes in mind and that the seven were operating independently and not always consistently introduces the first opportunity for problems.

Second, the Minneapolis Fed took the county data set and did their best to clean it up into a consistent, usable form, as described on their web page. I respect the work they did, but this is inherently difficult enough that it wouldn’t surprise me if some problems cropped up at this stage; some properties may be misclassified, for example. For larger units of analysis, these probably don’t matter much. But problems can arise once you start zooming in on a particular category of property in a particular census tract. If a number looks out of whack, it’s worth digging in to see what’s going on.

And third, we get the Strib’s summary of the Fed’s analysis. That seems to be a big area where problems originated. They made choices that amplified some of what was problematic at the first two stages, setting some of their parameters of analysis to maximize the anomalies in individual small areas and then not critically examining those anomalies but rather trumpeting them. 

Further, they introduced some major new problems just by getting the vocabulary confused. They incorrectly included condos in “single-family houses.” They attributed to the entire city of Hopkins data that is just from a single census tract within that city; likewise for Fridley. And then there’s the question of what differentiates “investor-owner” from a “corporation” or a “national buyer,” terms which the Strib seems to use interchangeably.

Finally, in addition to amplifying anomalies and botching some of the vocabulary, the Strib paid too little attention to what the data show about the evolution of the situation over time. One would never know from the article, for example, that some of the most heavily investor-owned census tracts have been coming down in investor ownership in recent years. Instead, we get the current status of those tracts (still heavily investor-owned) juxtaposed with metro-wide data on the trajectory (steadily more investor ownership).

The Fed’s homeownership data tool has four primary variables (or filters) you can set to find the number you’re looking for, in addition to a few others that just control the visualization. Those four variables you can control are 1) the cutoff number of properties to define investor ownership, 2) the type of properties to include (single-family homes, townhomes, condos), 3) whether to include properties owned by banks and public institutions, and 4) the granularity of the geographic units. 

By default, the Fed has these filters set to 10 properties; all of single-family homes, townhouses, and condos; excluding bank-owned and public/community-owned properties; and using individual census tracts.

In order to reproduce the data used in the Strib’s article and charts, I found it necessary to change the investor-owner cutoff to two, leaving the other settings at the Fed’s defaults. As I’ll discuss below, some of those default settings are themselves relevant to understanding what the Strib got wrong. 

First, however, let’s consider the impact of changing the definition of “investor-owned” from “an owner with 10 properties or more” to “any owner who owns at least two properties.”

The Fed’s published data set does not distinguish ownership by a single person (or married couple) from ownership by a corporation. It also does not distinguish local ownership from far-off ownership. Instead, the only way to get a handle on what kind of owner is in question is by looking at whether the owner lives in the property via the non-homestead tax status and how many properties the owner owns. 

The big national corporations that are the article’s ostensible focus would be included using either the Fed’s cut-off of 10 properties owned or the Strib’s two. But lowering the number all the way down to two also inadvertently sweeps in a bunch of other types of owners. This includes small-time local investors, who likely behave differently than big national firms (Do they pose the same issues, for example, of being neglectful landlords?). It would also incorporate wealthy individuals who buy vacation homes or have the luxury of not immediately selling their old home when they purchase a new one.

One place this shows up in the Strib’s data is near the end of their table of “top 20 Minn. census tracts with high investor property ownership” and the accompanying map. (Aside: the abbreviation “Minn.” in this caption seems inappropriate. The dataset covers the seven-county metro area, not the state.) At position 17 out of 20 is a census tract described as in “Oak Park Heights-Stillwater,” in Washington County. On the map, that’s the light tan blob adjacent to the St. Croix river. It’s the only census tract on the list outside the two core cities of Minneapolis and St. Paul, with the important exceptions of Fridley and Hopkins. (I’ll get into those two later.)

The table has a column labeled “share of single-family rentals that are investor-owned,” which for this particular census tract has a value of 14.4%. That matches what the Fed’s tool shows with the cutoff changed from 10 to two, but everything else left at the defaults. Aside: Note the column heading’s odd phrase “single-family rentals.” This is just plain wrong: we’re not looking at 14.4% of the residential units that are rented out, but rather 14.4% of all single-family homes, townhouses, and condos, including those that are owner-occupied. (This also excludes many rental units—apartments and duplexes—as both the Strib and Fed explain.) 

But anyhow, 14.4% of a certain group of properties is “investor-owned.” How critically does this number depend on the definition of “investor-owed” as being “properties owned by entities that own two or more properties?”

Let’s look at what the Fed’s team did. Changing the filter in the data tool back to its default of 10 properties owned drops the percentage from 14.4% down to 1.3%. On the map on the Fed’s site, you can see that the census tract goes from standing out in dark color to being just one of many in the middle of the range.

Census tract is darkly colored with 14.4% at cutoff 2.
Same census tract is more normally colored with 1.3% at cutoff 10.

So what’s happing here? Remember, this is a census tract that includes properties by the St. Croix River. Perhaps wealthy people have a second or third home there. Maybe a small-time local investor from elsewhere in the metro area has a property there they sometimes use themselves but often put on the short-term rental market via Airbnb. Or maybe a small-time investor from within that very census tract chose to buy the unit next to their own and rent it out on Airbnb. The reality is no doubt a mix of these scenarios and others. It’s complicated, but it surely has something to do with the particular circumstances of this area. It doesn’t really belong in an article about national corporate investors swooping in and gobbling up metro properties. The Fed’s threshold of “10 properties owned” for investor buyers would have been a better guide. 

OK, OK, I hear you saying, what about Fridley and Hopkins? Aren’t those cases what make the article so shocking? Again, Strib’s dramatic findings don’t hold up to closer scrutiny. Their decision to move the investor-owner threshold from 10 to two is still part of the story, but the bigger problems the piece runs into here have to do with the geographic granularity and the types of residences included.

First, to see what we’re fact-checking, it may help to quote what the Stib says about these two suburban cities. They first show up in the article’s lead: “Now, data show that some neighborhoods in Minneapolis and the entire suburbs of Fridley and Hopkins are being transformed by corporate ownership, a phenomenon that shows no signs of letting up.” These same two cities must also be the suburbs mentioned in “And in a half dozen neighborhoods and suburbs, they own more than 20% of the single-family houses.” 

That “half dozen neighborhoods” refers to six rows in the table of census tracts that are above 20%, two of which are labeled Fridley and Hopkins, at 27.1% and 24.8%, respectively. And at a later point in the article, we get another variation of the theme: “And in Fridley and Hopkins, more than 25% of the single-family houses are owned by an investor who doesn’t live there.” (Aside: 24.8% is not really more than 25%, but if the number were rounded to an integer percentage, one might think so. That’s a minor issue.)

So, let’s start taking this apart piece by piece. The first thing that jumps out at me is that the quoted text explicitly refers to “the entire suburbs of Fridley and Hopkins,” yet the data table is at the finer granularity of census tracts. If we were to look at the entire cities, would the percentage still be “more than 20%”? How about “more than 25%”? 

Conveniently, one of the selectable filters on the Fed’s site does precisely this—one can switch from census tracts to cities/townships. If we do that, leaving everything else as the Strib had it (including a cutoff of two properties), we find that the rate of investor-owned properties in Hopkins drops from 27.1% to 14.4% while Fridley’s rate goes from 24.8% to 11.1%. That’s still a substantial percentage of investor-owned properties in each city, but we are left with a picture that is much less dramatic than what the Strib achieved with the simple slip of using a particularly extreme census tract to represent the entire city.

OK, but what is going on in those two specific census tracts that makes them stand out as so extreme? And is that all that’s pulling the city-wide numbers up into the teens? Our old friend the cutoff of two vs. 10 may play a role, but that’s a squishy judgment call, so first, let’s dig into another outright misstatement. The two quotes about “more than 20%” and “more than 25%” both use the phrase “of the single-family houses.” And that’s not what the numbers are—they include townhouses and condos. Thankfully, the Fed has checkboxes we can uncheck, so let’s do that.

Limiting to just single-family homes but leaving everything else alone (in particular, cutoff two), the city of Hopkins drops to 2.4% investor ownership, less, for example, than neighboring St. Louis Park, which is 2.6%. Likewise, Fridley is down to 3.5%, less than neighboring Columbia Heights’s 4.2%. Changing the Fed’s tool back to the census tract level, and limiting our search to just single-family homes drops the Hopkins stand-out tract from 24.% to 2.1%; the tract in Fridley drops from 27.1% to 4.6%.

In both cases, the seemingly huge numbers are being driven not only by the focus on extreme census tracts but also by the inclusion of a large number properties that are classified as investor-owned condos. I’m really not sure what’s going on with those. If someone cared, it would make sense to dig into the specifics of those investor-owned condos. But that’s a side issue compared to the fact that the article’s claim about these cities just isn’t true. National corporations are not buying up a huge fraction of single-family homes in Fridley or Hopkins. In fact, if we not only focus on single-family homes but also follow the Fed’s lead and turn up the cut-off to10 to better approximate those national corporations, we find that the city of Fridley has investor ownership of 1.1%, only slightly over the metro-wide percentage.

And although this number has been rising since 2006, the trajectory has closely followed the metro-wide one; there’s no sign that some huge gobbling-up is taking place there. Instead, we’re back to the article’s opening, which was establishing the contrast point for their dramatic lead: “Twin Cities residential real estate has been slowly reshaped over the past few years by national buyers who turn single-family houses into rentals, but the numbers appeared small against the overall market, and the effects marginal.” Having debunked the dramatic contrast with that, we’re left with a slow reshaping that is small and marginal.

City of Fridley, limited to single-family homes and with a cutoff of 10, shows the same trend as the metro.

The data for Hopkins are even further from the article’s narrative. With the entire city included, a limitation to single-family homes, and the investor-owner cutoff set to 10, the investor ownership is only 0.3%, well below the metro-wide 1.0%. And unlike Fridley and the metro as a whole, Hopkins’s percentage has not been rising. It was highest in the early years of the dataset (2006–2008), fell off from there, partially recovered, and has been quite stable since 2014. So very definitely there is no sign that Hopkins single-family houses are actively and recently being bought up by national corporations.

City of Hopkins, limited to single-family homes and with a cutoff of 10, does not look worth an article.

Having broached the topic of how investor ownership has changed over time, let’s dig into that more. This isn’t something the article really gets into much, aside from showing the metro-wide rise from 1.8% to 4.1% (using the cutoff of two and including townhouses and condos). But you’d think it would be an important topic if this is a story about what’s been happening lately to transform the situation rather than just about the longstanding reality. Recall again the article’s lead, “Now, data show that some neighborhoods in Minneapolis and the entire suburbs of Fridley and Hopkins are being transformed by corporate ownership, a phenomenon that shows no signs of letting up.”

So let’s take a look at one of the North Minneapolis census tracts that genuinely does have high investor ownership of single-family homes. To make it personally relevant, I picked a tract in the Folwell and McKinley neighborhoods where one of the owner-occupants is a family member of mine. Even with the limitation to single-family homes and cutoff of 10, that tract clocks in at 11.5% investor ownership (141 houses out of 1,231). Throwing townhouses and condos into the mix doesn’t change that by much, but if we also crank the ownership threshold down to two, we get the Strib’s number of 22.3%, the fifth-highest on their list of top 20. But the question is, how has this number changed over time?

Using the Strib’s methodology, the percentage of investor-owned homes in the census tract started at 12.6% in 2006, rose to a peak of 27.3% in 2017, and over the past four years has fallen off to the current number of 22.3%. If we use the more narrow criteria of cutoff 10 and only single-family houses, the numbers are lower, but the pattern is the same: starts at 1.4%, rises to a peak of 14.4% in 2017, and now has fallen back to 11.5%.

A Folwell/McKinley tract, with cutoff 2, shows recently decreasing investor ownership.
The pattern is similar when limited to single-family homes and an investor-owner cutoff of 10.

What can we take away from this? There are some specific areas, this tract included, that have long faced challenges to owner occupancy and even in 2006 had substantial numbers of single-family houses rented out by large-scale landlords. As the bubble in subprime mortgages and home prices burst, this investor ownership became more pronounced, continuing to grow for a decade. However, the recent trend has been for increasing owner occupancy in these hard-hit areas. Is that the story the Strib’s article tells? No. But streets.mn readers should recognize it as the story the data tell.

    Amazing analysis here digging below the headline. I would be very impressed if the Strib responded or even the cities of Hopkins or Fridley.

  2. Eric AnondsonEric Anondson

    So glad you wrote this, and a very great deep dive and presentation of the data.

    That condo association fight has been so fierce (and generated a handful of Strib story coverage) that the city government nearly got involved because it’s such a significant amount of residents in a smallish suburb.

    I’ll have to keep this story on bookmark when the narrative of Hopkins being eaten up by out of state investors gets dropped in Nextdoor threads out here. This post has been a service!

  3. Pine SalicaPine Salica

    The condo numbers might be because when you build a new condo building (or create one from a warehouse or whatever) the association owns a lot of the units and sells them off over the years to prevent chaos. So they might still be the owners of 2-9 units for years after the opening of the building.
    Thanks for the article!

      The Fed researchers did make an effort to avoid this artifact. From their web page: “The MetroGIS data include newly constructed or remodeled homes and condominium units that are on the market and are thus still owned by their construction company or developer. We identified these entities based on their names and excluded any properties associated with them from the sample.”

      As far as I can tell, what’s happened is that just as in the 1970s, apartment buildings were converted to condos, so in this century, there has been some movement to convert condo buildings back into de facto apartment buildings, or at least largely so, by buying substantial numbers of units to rent out. In particular for the Hopkins case there was apparently a whole bunch of tightly related LLCs that owned the units. So this really is a case of investor ownership, but it presumably raises different issues than with single-family houses.

      1. Pine SalicaPine Salica

        oh interesting. handcrafted artisinal data specifically to avoid that issue. wouldn’t have thought!
        (does it actually raise different issues? a home is a home… but tell that to the die-hard detached dwelling fans I guess)

  4. Monte Castleman

    So yeah, if we’re going to get indignant about something, we should at least have the proper data.

    As an anecdote, a few months ago started mapping out all the residential single family lots within a half mile of me, expecting to find a lot of out of town landlords. I just quit when about 2/3rd done because I did not, of about 300 properties, I found 25 that were not homesteaded, and of those a grand total of 6 where the property owner came back to an out-of-state corporation, and one of those was a flip in process and is now for sale. The out of state LLC owned house kitty-corner from me sat on the market for months and had a price reduction at a time where other properties were selling within a week above asking price. It was too much house for the neighborhood; for what it cost you could get a new construction entry-level house for not much more.

    There’s also no correlation I’ve found between neighbors that are noisy, leave their yards unkempt, leave cars parked on the street after it snows, or cause other problems and their ownership or rental status. The people next door that invited dozens of people over (but not us) for parties that lasted beyond midnight just about every weekend in the summer were owners.

    Seems like way too much data and analysis. Rather than quibble about whether “investor-owned” means 2 properties or 10, the focus of the Strib article appears to be on the corporations that have invested billions of dollars in 1000s of homes, in the Twin Cities and elsewhere.

    The housing bubble burst and the Blackstones of the world swooped in with billions of dollars and bought every owner-occupied house they could grab, sight unseen, with cash and without inspection fees and finance costs, as long the properties fit their mold.

    The corporate investor owned single-family houses are mostly in inner ring suburbs. According to the Strib article, Invitation Homes owns more than 800 in places like Fridley and Roseville. There’s 2 Invitation Homes rental properties within a stone’s throw of my house in Roseville.

    Typically, the Invitation Homes properties are post-war 3-br ramblers built in the 50’s and early 60’s, often updated with a finished basement to accommodate a 4th bedroom. Invitation Homes often rents the single-family homes to 4 or more persons, often resulting in 4 or more vehicles parked in driveways on streets with no sidewalks.

    Due to low interest rates, low supply and high demand, the houses Blackstone bought with its billions of dollars after the crash have nearly doubled in price, while the new appliances and other improvements invested in the properties are now shot. As interest rates begin to rise, and before the current bubble goes bust, the real estate investors, as Blackstone has already done, cash in and haul away the loot. Meanwhile, the deteriorating rental properties surrounded by overpriced houses bought with teaser rate mortgages, and the deteriorating big box apartment buildings next to freeways that the billionaire real estate investors looted for all they’re worth with development fees, tax-exempt interest payments, and construction contracts, lead to the next crash.

    After the next, I suspect, not too distant crash, with far greater wealth, Blackstone and others like it, will no doubt swoop in again and buy every house, with cash and without inspection and finance fees, that fits their template. If the pattern is repeats often enough, eventually Blackstone and others like it monopolize the housing market, and we’re all their tenants, working to pay rent to Blackstone, whether we like it or not.

    It’s no accident that many cities, including Minneapolis and St. Paul, are already mostly rental properties. Not everyone needs or wants to own a house, but I think most would agree, the more that can afford to, the better. If only the billionaire investors, with cash and without inspection fees and finance costs, can buy houses, that it not a good thing.

      “ Seems like way too much data and analysis.”

      I hate it when there are so many facts about actual errors in reporting about suspected trends we’re all wanting to understand better so we can come up with policies that work…

    2. Max HailperinMax Hailperin Post author

      Thank you for raising the normative question of whether the current level of investor ownership is too high, too low, or just right. That topic would merit a streets.mn article of its own. I did not address it in my article, instead confining myself to the descriptive question of whether the Star Tribune correctly portrayed the current level.

      The simple facts are that condos are not single-family houses, individual census tracts are not entire cities, and the fraction of single-family houses in Hopkins and Fridley that are investor owned is nowhere near 25%. That’s true whether one defines investor ownership as starting at 2 or at 10. I am not quibbling with the Star Tribune’s definition. I am pointing out that even using their own definition, they are just plain wrong about the current level of investor ownership.

      As to whether the actual current level is undesirable, and if so, what to do about that, I am happy to leave that topic to you.

      1. Sheldon Gitis

        I assume you are not disputing that one corporation has bought, according to their website, “nearly 80,000 beautifully updated homes for lease in desirable neighborhoods all across the nation – with close proximity to jobs and good schools” including, as the Strib reports, more the 800 in the Twin Cities metro area.

        As I believe the Strib accurately reported, that’s more than 800 previously owner-occupied single-family homes that are no longer available to owner-occupants, even if the cost of ownership would be less than the cost renting.

        Is there anyone who thinks having one national corporation, with offices in more than a dozen states, convert more than 800 Twin Cities metro area single-family houses into rentals, is a good thing?

        What to do about it? Beats me. Or as the saying goes: “There ought to be law.”

    The world could use a few more million people like you who analyze data to determine what it means not to support an agenda. Well done….
