When Bob Murray joined KSI Management as president roughly one year ago, he had a pretty clear agenda: to grow the company, in part by tapping new sources of revenue. Ancillary income is a key part of his strategy. “Whether you're managing high-end luxury units or the lowest of the low-income tax credit units, ancillary income is the only remaining uncharted field for additional, needed revenue,” says Murray. KSI is a Centreville, Va.-based company with 10,000 units.
