Would Banning Wall Street From Buying Homes Help Arizona Buyers?
If you’ve tried to buy a home in Arizona over the past few years, you’ve probably felt it: multiple offers, cash buyers, tight inventory, and prices that climbed faster than incomes. Wall Street buying homes has become one of the hottest housing debates in America… So when headlines say the President wants to block “Wall Street” from buying single-family homes, it sounds like a potential fix. But would it actually help buyers here in Arizona? The honest answer is: a little in certain neighborhoods, but it’s not a silver bullet. Let’s break this down in plain English, with a focus on what’s happening right here in the Phoenix-area market.
How Big Is “Wall Street” in Single-Family Homes, Really?
Nationally, large institutional investors that own hundreds or thousands of homes control a surprisingly small share of the overall housing market.
Across the U.S., there are about 82 million single-family homes. Large institutions own roughly 0.5% to 1% of them.
Even when you look only at single-family rentals, where these firms are more active, institutions with 100+ homes still represent just a minority share. Most rental homes are owned by small, “mom-and-pop” landlords who own fewer than 10 properties. So nationally, banning large investors wouldn’t suddenly flood the market with homes.
But Arizona isn’t the national average.
Why Arizona (Especially Metro Phoenix) Is Different
Phoenix–Mesa–Chandler and the entire East Valley are one of the metros where institutional investors made a deliberate, concentrated push after the 2008 housing crash.
The biggest player locally is Progress Residential (owned by Pretium). As of early 2025, Progress owned an estimated 8,326 single-family rental homes in the Phoenix metro area. That’s roughly 8–9% of their entire national portfolio, which is a heavy concentration in one market. Other major institutional owners, like Invitation Homes, Amherst, and American Homes 4 Rent, also have a presence here, though their exact local counts aren’t always publicly disclosed. Combined, institutional owners control low-five-figure numbers of homes metro-wide, which is still a minority of total housing but meaningful in specific neighborhoods.
Where You Feel It Most
The impact isn’t spread evenly. It’s most noticeable in:
- East Valley and Southeast Valley areas like Mesa, Chandler, Gilbert, Queen Creek, and San Tan Valley
- West Valley areas like Goodyear, Buckeye, Avondale, Surprise, Glendale, and Peoria.
- Newer subdivisions (2010+)
- Entry-level and mid-price single-family homes (often 3–4 bedrooms)
In some subdivisions, institutional owners control a noticeable share of rentals on the same street or within the same HOA, which clearly affects competition and pricing.
Would a Ban Lower Home Prices in Arizona?
Not dramatically, but it could reduce some pressure at the margins.
Here’s why:
What a Ban Would Do
If large institutions were blocked from buying more single-family homes:
- There would likely be fewer repeat, cash buyers bidding aggressively in certain entry-level neighborhoods.
- Builders might redirect more inventory toward owner-occupants instead of bulk investor sales.
- Some first-time buyers could face slightly less competition in targeted price ranges and ZIP codes.
What a Ban Would Not Do
- It would not force institutions to sell the thousands of homes they already own
- It would not solve the inventory shortage, which is driven by underbuilding, zoning limits, land costs, and population growth.
- It would not eliminate investor competition, since small investors still make up the majority of investor purchases.
Without a requirement that large investors sell existing homes, the number of homes available for purchase doesn’t change much — and that limits the impact on prices.
The Bigger Truth: Supply Is Still the Real Problem
It’s easy to point at Wall Street, and emotionally, it makes sense. We understand why they are buying homes; everything comes back to supply and demand (remember toilet paper in 2020?) But even in Arizona, institutional buyers are not the primary reason housing is expensive.
The deeper issues are:
- Years of underbuilding after the Great Recession – The country built about half as many homes in the decade following the Great Recession as it did the previous decade.
- The population continued to grow, contributing heavily to our eventual affordability crisis. Maricopa County grew from just over 3 million to about 4.4 million by 2020.
- High construction and labor costs
- Zoning and land-use restrictions
- Strong population and job growth in the Phoenix metro
Until those are addressed, banning large investors alone won’t magically make homes affordable again.
What This Means for Arizona Buyers Right Now
For most buyers:
- You are still competing more with other families and small investors than with Wall Street.
- The opportunity is hyper-local; some neighborhoods will feel relief, others won’t
- Strategy matters more than headlines.
Understanding where institutional buyers are concentrated and where they aren’t can make a real difference in how competitive your offer needs to be.
Final Takeaway
Blocking Wall Street from buying single-family homes would be highly visible and politically popular, but in Arizona, it would likely provide targeted, modest relief rather than a market reset.
For buyers and homeowners, the real advantage comes from understanding:
- Neighborhood-level dynamics
- Inventory patterns
- Financing and negotiation strategies that work in this market
I am 100% in favor of getting Wall Street out of the single-family home business. There are too many headwinds preventing home builders from bridging the housing deficit, and this is certainly one of them. There are plenty of other investment opportunities for Wall Street that do not involve competing with the hardworking Americans who have worked their behinds off to buy their first home for their family.
