D.R. Horton is one of the largest homebuilders in the United States, constructing single-family homes across a wide range of price points and geographic markets, from entry-level starter homes to higher-end custom builds. The company has built its business around high sales volume across many markets rather than concentrating in a few premium locations, a strategy that has made it the largest homebuilder by units sold for many consecutive years. Homebuilding is closely tied to mortgage rates and housing affordability, since higher borrowing costs directly reduce how many buyers can afford a new home at a given price point, making interest rate movements a significant driver of demand. D.R. Horton also operates a mortgage financing subsidiary that helps buyers secure home loans, giving it an additional revenue stream tied directly to the home sales its core homebuilding business generates.
