(WCSC) - The price of a home in Charleston continues to skyrocket as more people flock to the area. “We cannot build houses fast enough to keep up with demand of people migrating to our city,” Matt O’Neill, CEO of Matt O’Neill Real Estate, said. Data generated by the Multiple Listing Service shows the Charleston area has hit its lowest supply of houses in 20 years with around 2,300 homes on the market. The same data shows a need for 10,000 more listings to bring the market back into balance.
