BALTIMORE — Walker & Dunlop has provided a $20.8 million loan for the acquisition of the 196-unit Waterloo Place Apartments. The Baltimore property, which was constructed in 1991, features a swimming pool, a fitness center and monitored garage parking. The complex is currently 95 percent leased. Freddie Mac's Capital Markets ExecutionSM program financed the 10-year loan, which carries a 30-year amortization and an 80 percent loan-to-value ratio. Charlie Mentzer of Walker & Dunlop's Atlanta office secured the loan, which was originated by John Street of Allied Mortgage & Realty Corp.
