    Question

    Berkshire Hathaway Commits $6.8B to Homebuilders Amid 7.5% Mortgage Rates

    Direct answer

    Berkshire Hathaway expanded its residential construction allocation with a combined $6.8 billion deployment across Lennar and the acquisition of Taylor Morrison Home. The conglomerate added $53.9 million to its Lennar position in late September, establishing an 11% ownership stake valued at $2.2 billion. The accumulation occurs against persistent headwinds in private residential real estate, where 30-year fixed mortgage rates near 7.5% have weighed on builder confidence surveys. Large public builders continue leveraging scale advantages and mortgage rate buydowns to gain share from existing home inventory. — bullish pressure on BRK.B.
