JOPPATOWNE, MD. — Tal Savariego of Meridian Capital Group’s New York City office has arranged a $10 million loan for an expansion of the 300-unit Harborside Apartments in Joppatowne. The expansion will accommodate the influx of workers expected to help with the nearby Aberdeen Proving Ground’s base realignment campaign. The loan comes with a 3-year, interest-only term. Harborside, the only multifamily property in Joppatowne, was built in the mid-1970s.
