Why Warren Buffett is Buying Lennar Stock, and How to Invest in Housing Like a Billionaire

During the latest Market on Close livestream, John Rowland, CMT, highlighted an under-the-radar shift happening in the U.S. housing market — and why homebuilder stocks and ETFs might be primed for a breakout.
With mortgage rates still elevated, single-family home affordability has hit a wall. But homebuilders aren’t sitting idle. Instead, they’re pivoting to a new model: “build-to-rent” communities.
The New Builder Playbook: Build-to-Rent
Here’s how it works:
Builders construct multifamily townhouses or rental-focused communities.
They fill them with tenants.
Then they sell the entire project to institutional buyers like BlackRock (BLK), Blackstone (BX), or KKR (KKR).
This business model is working, and it’s supporting the charts of publicly traded builders with a strong footprint in the multifamily space.
Toll Brothers (TOL), for example, has shown a strong, constructive chart pattern that correlates closely with the homebuilders ETF (XHB).

Buffett’s Signal: Berkshire Doubles Down
This isn’t just a technical story; it’s fundamental. Warren Buffett’s Berkshire Hathaway (BRK.A) (BRK.B) recently added to its stakes in D.R. Horton (DHI) and Lennar (LEN), two of the top multifamily builders. That move underscores the idea that even if single-family demand is cooling, the multifamily “build-to-rent” trend could power growth.
Technical Tailwinds
Rowland pointed out a looming “golden cross” setup, where the 50-day moving average crosses above the 200-day — often a bullish confirmation.
Combine that with relative strength in the sector despite broader market profit-taking, and it paints a compelling technical backdrop.
Why Homebuilders Matter to Investors
- Macro-sensitive sector: Housing reacts directly to mortgage rates and Fed policy.
- Diversification play: Homebuilders offer exposure outside of tech-heavy leadership.
- Early rotation indicator: Housing strength often signals renewed consumer and credit demand.
