I live in Charleston SC as well. I bought my first home here for $40,000, 2 bedroom, 2.5 bath, 1150 SQFT. That was 1999, though. I sold it in 06 for $84k.
I got hosed on a $165,000 I built near the end of the bubble. Sold it a couple years ago for what I paid. Lost 20-30k total.
Built a $250k in 2014, now worth $350 or more.
Charleston is blowing up because Silicon Harbor is real. Our area is flooded with software jobs. Big old companies, new start ups, VC guys making it rain. Boeing, Volvo, Mercedes; they bring so many jobs to the area and tons of money.
