Berkshire Hathaway's $1 billion homebuilding investment indicates Warren Buffett's confidence in a future U.S. housing market rebound.

Berkshire Hathaway 's investment is a huge endorsement for the Dividend King -- Nucor has increased its dividend for 52 straight years, every year since it started paying dividends in 1973. Here's a look at what Buffett's company likely sees in the steel stock and whether it's a worthwhile option for income-seeking investors.

Berkshire Hathaway revealed four new investments Thursday in steelmaker Nucor, insurer UnitedHealth and two of the nation’s biggest homebuilders — Lennar and DR Horton — but only one of the investments was big enough to ensure that legendary investor Warren Buffett may have handled them.
