Warren Buffett’s heir just made another big housing market bet. Why?

Five weeks after Greg Abel—who became president and CEO of Berkshire Hathaway on January 1, 2026, succeeding Warren Buffett, who remains chairman of the board—made his first major deal by announcing that Berkshire Hathaway would be buying Taylor Morrison—a deal that will make the conglomerate Buffett built America’s No. 4 homebuilder—Berkshire’s home-building arm is on the move again.

This time, the target is far smaller, but the pattern is the same: Berkshire keeps doubling down on site-built homebuilding, even as the industry grinds through a post-boom cooling cycle.

Last week, Mungo Homes—a unit within Berkshire Hathaway-owned Clayton Home Building Group—announced last week it has acquired McGuinn Homes, a South Carolina-based homebuilder with more than four decades in the Southeast. Financial terms were not publicly disclosed.

In 2025, McGuinn Homes completed 993 new-builds—up from 581 in 2024, 337 in 2023, and 309 in 2022.

The Build-to-Rent angle

McGuinn Homes isn’t just a for-sale homebuilder. Sources tell ResiClub that Build-to-Rent (BTR) has, at times, made up the bulk of McGuinn’s business.
