Why I'll Never Sell This Under-the-Radar Warren Buffett Stock

Berkshire Hathaway built a sizeable position in Lennar, buying about $800 million of stock in August and later increasing the stake to roughly $910 million (it also bought then exited a $191.5 million position in D.R. Horton). Lennar completed a spin-off of its land assets into Millrose Properties, a REIT that collects monthly option payments and pays a quarterly dividend, materially reducing Lennar's land exposure and freeing capital for core homebuilding operations. The company also closed the acquisition of Rausch Coleman’s homebuilding operations while Millrose took the related land with purchase option agreements back to Lennar, reinforcing a land‑light strategy management says should lower cyclical land risk and support long‑term shareholder value.

Analysis

Market structure: Berkshire’s (BRK.B) accumulation and Lennar’s (LEN.B) Millrose (MRP) spin create a clearer winner set: land-light builders (LEN, MRP) gain pricing power and lower capital intensity while vertically integrated, land-heavy peers (DHI) face tighter ROIC and working-capital strain. Expect modest share gains for Lennar over 12–36 months as option payments to Millrose convert fixed land exposure into recurring income, flattening LEN earnings volatility and allowing faster homebuilding production scale. Housing demand signals are mixed — strong localized demand supports lot absorption but rising 10y yields >4.25% would compress affordability and slow starts by 10–20% year-over-year in sensitive metros.

Risk assessment: Tail risks include a >200bp Fed tightening shock or mortgage-rate spike (30y >7%) that could collapse starts and option exercise rates at Millrose, and related-party/REIT governance scrutiny leading to valuation haircuts of 20–40% for MRP. Short-term (days–weeks) price moves will track mortgage rates and Fed commentary; medium-term (3–9 months) depends on Rausch Coleman integration and lot-sale cadence; long-term (12–36 months) rewards accrue if LEN converts freed capital into stable FCF and <8% gross margin erosion. Hidden dependency: Millrose cashflows rely on external builder demand — if third-party builders retrench, MRP distributions are at risk despite option payments.

Trade implications: Direct play: establish a 2–3% long position in LEN (add on pullback ≥10%) and a 1–2% income position in MRP for current yield (target total return 20–30% over 12–24 months if housing holds). Pair trade: long LEN vs short DHI (size 1:1 notional) to capture ROIC re-rating; target spread capture of 15–25% if Lennar outperforms over 6–12 months. Options: buy a 9–12 month LEN call spread (e.g., +0.5% notional, 0-30% OTM cap) to lever upside and buy 3-month 10–15% OTM puts sized to limit portfolio downside if 10y>4.5% post-Fed.

Contrarian angles: Consensus underestimates governance and counterparty risk at Millrose — markets may underprice a scenario where option fees fall 25% if lot demand softens, producing a >15% hit to MRP distributions. Berkshire’s purchase is tactical; don’t assume perpetual conviction — a sell-off by BRK could force short-term volatility. Historical parallels (builders spinning land into REITs) show initial multiple expansion then mean reversion once third-party demand normalizes; hedge MRP exposure with short regional land developers or buy downside protection on MRP for 6–9 months.

Key Decisions for Investors

• Establish a 2–3% long position in LEN.B (scale in on any pullback ≥8–12%) with a 12–24 month horizon; take profits if LEN rallies +25–35% or if company fails to grow quarterly SG&A-adjusted EBITDA margin within 2 quarters.
• Buy a 1–2% yield position in MRP (MRP) for dividend income but hedge with a 6–9 month put (10–15% OTM) sized to protect 50% of position if MRP distribution coverage falls below 1.1x or lot-option revenues decline >20% QoQ.
• Implement a pair trade: long LEN (notional) vs short DHI (DHI) equal notional sizing; target 15–25% relative outperformance in 6–12 months, exit if spread narrows to <5% or macro-driven 10y yield exceeds 4.75%.
• Use options to leverage upside while limiting drawdown: buy a 9–12 month LEN call spread sized to 0.5–1.0% of portfolio (buy calls 20–30% OTM, sell 40–50% OTM) and buy 3-month puts 10–15% OTM across exposure if 10y Treasury >4.5% indicating tightening shock.
• Reduce exposure to capital-intensive, land-heavy builders by 25% in favor of land-light residential REITs and LEN if mortgage rates remain <6% over the next 3 months; re-evaluate after next two monthly new-home sales releases and the Fed meeting (within 60 days).
