• Housing starts sit below 1.5 million while family formations go unmet, creating structural demand that Buffett is betting outlasts Lennar’s current margin squeeze.

• Gross margin compressed to 15.8%, net income fell 52% year over year, and nearly 50% of Lennar’s visitors cannot immediately qualify at today’s mortgage rates.

• The biggest 401k decisions tend to get made once and never revisited: when to roll it over, what to hold inside it, and when to start taking money out. That is exactly what the report: 401k & IRA Tips and Answers was created to address, and it is free today. Read more here. (Sponsor)

At $81.47, Lennar (NYSE:LEN) looks compelling on a research basis. The sharpest confirmation came from Warren Buffett, who crossed 10% ownership of the homebuilder with a September 17, 2026 transaction date, one day after Lennar missed earnings and cut its full-year delivery guidance. Buffett appears to be pricing the decade of housing scarcity behind the weak quarter.

Lennar is the second-largest US homebuilder, running a land-light model that controls roughly 488,000 homesites while owning fewer than 2.5% of them. Fiscal Q3 2026 landed with adjusted EPS of $1.23 against a $1.2963 consensus, revenue of $8.05 billion, down 8.52% year over year, and new orders 9% lower. Management then trimmed full-year 2026 deliveries to between 80,000 and 81,000 homes from a prior range of 82,000 to 83,000.

A portfolio manager on Marketplace captured the setup Buffett was buying: “There is a buildup of family formations which should normally move into homes. We’re not seeing that because the housing supply for them just isn’t there.”

Why Buffett Crossed the 10% Line at a 12-Month Low

Berkshire moved with Lennar down 35.1% over the past year. In August, existing home sales printed 3.98 million annualized, the softest reading in the trailing year, while housing starts, or the number of units under construction, sit at 1.27 million, below the 1.5M threshold. Undersupply coupled with a frozen resale market creates structural pull for new construction.

Lennar’s operating machine is improving. Construction cost per square foot is down 6% year over year and 14% since Q4 2023. Cycle time hit a record low 116 days. In its latest quarter, management repurchased 3 million shares for $256 million. Nevertheless, Lennar CEO Stuart Miller warned, “The fundamental shortage of housing in America has not been solved.”

Where the Bear Case Still Bites

Gross margin on home sales compressed to 15.8% from 17.5%, with incentives near 12%. Net income fell 51.96% year over year. Q4 guidance calls for gross margin of 15.5% to 16.0%, meaning the trough is not confirmed.

The 30-year mortgage sat at approximately 6.8% at quarter end and has crept higher since. Miller said Lennar is not building its plan around Fed rate cuts, noting that in many communities, “Almost 50% of our visitors cannot immediately qualify” for a mortgage. Resale supply is competing aggressively in Texas and Florida, Lennar’s two biggest markets.

What Keeps Some Investors on the Sidelines

There is a hold case for the stock. Lennar looks cheap because earnings are still falling. FY2025 EPS was $7.98. Q4 guidance implies an EPS range of roughly $1.30 to $1.65, extending the trajectory lower. Buying before Q4 clears the tape risks another downdraft, especially if mortgage rates push higher.

The Buffett signal reframes the debate for investors weighing the setup. Crossing the 10% threshold triggers faster disclosure than 13F reporting, so Berkshire is on record in near real time.

Price, Targets, and Performance Behind the Verdict

Lennar trades at $81.47, with a market cap near $19.6 billion. Wall Street’s consensus 12-month price target is around $92, implying modest upside on a Reduce-leaning consensus. Buffett’s disclosed position is the stronger signal.

Against the S&P 500’s roughly 12.5% year-to-date gain, Lennar’s 20.7% YTD decline is a gap of more than 30 points. Over one year, Lennar is off 35.1% against the S&P’s roughly 16% gain.

Verdict: Why Buffett’s Signal Anchors the Thesis

At $81.47, Lennar screens as an interesting research case. Here is why.

Appreciation runs through three catalysts: easing in mortgage rates from the current ~7% zone, clearing of older high-cost land as Lennar delivers through it, and margin normalization from today’s 15.8% toward the low 20s that defined 2022. Each lever requires time rather than a boom, and Berkshire has just that.

The risk/reward profile is asymmetric. Lennar has discounted a soft Q4, deteriorating orders, and no Fed help. Invalidators hover, including mortgages sustained above 7.5%, order declines accelerating into double digits, or debt-to-capital breaking meaningfully above the current 16.6%. Investors should watch Q4 deliveries against the 22,000 to 23,000 guide and incentive percentage each quarter.

When the country’s most patient investor buys 10% of a beaten homebuilder the day after it cuts guidance, the research case is to weigh the scarcity thesis alongside him before making a move.
