Believing that an energy makeover is just the ticket for attracting and retaining residents, Spencer Noecker, co-owner of NFN Investments, LLC, has made energy-efficiency improvements to 271 dwelling units. Noecker has installed floor and attic insulation, new replacement windows and doors to help keep residents comfortable year-round, saving tenants in 271 dwelling units an estimated $86,579 over a five-year period. NFN Investments raises the rent to at least partially cover its investment. “Tenants don’t mind paying a bit more if it means they save on utilities,” said Noecker.
