Southwest Charlotte/Steele Creek housing update for April 2019. Charlotte, North Carolina’s Southwest/Steele Creek areas (28273 and 28278 zip codes) remain fundamentally seller markets with tight inventory and homes selling at higher prices. The Steele Creek area (28273) had just 1.4 months of inventory in April. Fortunately, both areas had an increase in new listings in April. But little room for buyers to negotiate with 28273 zip code sellers receiving 100% of their ask price and 28278 zip code sellers receiving 98.5%.
