After seven years of work and more than $18 million invested, Harbor Village, a new affordable housing development in Carlisle, Pennsylvania, officially opened its doors in January.

The 40-unit rental development came together thanks to Safe Harbour, a housing nonprofit based in Carlisle.

By the time Safe Harbour started screening prospective tenants, there were over 400 applications, said Scott Shewell, the group’s long-time president and CEO.

“And I still get calls every day,” he told USA TODAY.

The median apartment rent in Carlisle was $1,259 in May. It was one of the fastest-growing areas for rent prices that month, up 6% from a year ago, according to a USA TODAY analysis of Apartment List data.
