In a move to streamline operations and cash in on the home building renaissance, Weyerhauser is selling its home-building unit. The prize, 27,000 lots including 18,000 in market-constrained litigation happy California, mostly in L.A. and San Diego. Assuming no goodwill, if the home-building unit sells for $3 billion, that’s just $110,000/lot. At $4 billion it’s $150,000/lot. At those prices, the buyer will be a public builder of move–up homes.
