Real estate properties in downtown Charleston offer a lot for prospective buyers, however reasonable prices for most they do not. The average one bedroom condo in the downtown peninsulas most desired boroughs will start usually at $350,000. The other part of downtown Charleston is called “outside the crosstown”, which really means the zip code 29403 and homes there are usually more affordable, but also less desirable. As many of the boroughs in this part of downtown are still up and coming so you’ll find that a lot of the houses for sale here need a lot of work or complete tear downs all together.
