Unfortunately it really makes no difference what you figure you need, want or think the property is worth. You are competing with foreclosures and short sales for best price and other people who must relocate for best condition.
You should price your home taking the current market and your property's condition into consideration. A Realtor can give you information on recently sold comparable properties (CMA) to help you understand the market conditions in your immediate area. You could also call a appraiser to get an estimate of value. The Realtor will probably do their work for free, and an appraisal will run a few hundred dollars. In Texas, the refrigerator does not have to convey with the property, nor does the washer and dryer - you may get more by selling those out of contract.
Good luck in your move, Charleston is a charming city - what a great place to retire!
