The Graham Cos., best known as the developer of Miami Lakes, has borrowed $120 million to refinance 29 properties it owns in the town in a transaction aided by Walker & Dunlop.

The Graham Cos. started as a pioneering dairy in 1930s South Florida, eventually growing into a development company. It owns and operates everything from apartments to hotels, and still is active in farming with a dairy in Glades County and a pecan orchard and an Angus beef ranch, both in Georgia.
