Most of your claims are opinions. An alleged factual one, Blackstone and BlackRock owning most of our houses, is hugely wrong. Grok: No, Blackstone and BlackRock do not own most (or even a significant portion) of American houses. 
This is a persistent myth, often fueled by confusion between the two companies and exaggeration of institutional investor activity in the single-family rental (SFR) market. Here’s a clear breakdown based on available data:
BlackRock
• BlackRock does not buy individual single-family homes. It is primarily an asset manager that invests client money (pensions, retirement funds, etc.) in a wide range of assets, including some real estate securities, mortgages, or funds. It has explicitly stated it is not in the business of purchasing houses. 
• Claims of massive ownership (e.g., hundreds of thousands of homes) are false or stem from mix-ups with other firms. Any indirect exposure is minimal through broader investments. 
Blackstone
• Blackstone (a private equity firm) has been more active in residential real estate, particularly through acquisitions and platforms like Tricon Residential and Home Partners of America. It owns or has interests in tens of thousands of rental homes (estimates around 58,000–60,000 SFR properties in recent years, with broader rental holdings). 
• Even so, Blackstone itself states it owns only about 0.06% of U.S. single-family homes. Institutions overall own roughly 0.5% of the total single-family housing stock. 
Broader Context on U.S. Housing and Institutional Ownership
• The U.S. has roughly 140–150 million total housing units, with around 80–100 million single-family homes (detached/attached). Single-family rentals total about 14–15 million. 
• Large institutional investors (firms with 1,000 homes) own only a small share nationally: estimates range from ~0.3–0.6% of all single-family homes or ~3–4% of single-family rentals. Mom-and-pop landlords (individuals with a few properties) dominate the rental market. 
• The top institutional players (e.g., Invitation Homes, Progress Residential, American Homes 4 Rent) collectively own hundreds of thousands of homes, but this is still a tiny fraction overall. 
• Concentrations are higher in specific Sun Belt metro areas (e.g., ~20–25% of SFRs in places like Atlanta), but even there, it’s not “most” homes. 
Institutional purchases spiked after the 2008 crisis (buying distressed properties) and during the pandemic but remain limited. Recent policy discussions (e.g., under the Trump administration) have targeted large investors, but their overall footprint is small compared to the broader housing shortage driven by supply constraints, zoning, construction costs, and demand. 
The myth often confuses asset managers (BlackRock), private equity (Blackstone), and smaller investors, while ignoring that most Americans own or rent from individuals. Housing affordability issues are real but stem more from underbuilding and other factors than these firms “owning most houses.”
