Generally, the hardest months to sell a house in South Carolina are the winter months, specifically January, December, and February. During this time, there is typically less buyer activity due to the holidays and colder weather. This can lead to homes spending more days on the market. However, the mild winters in Charleston can still attract serious, motivated buyers, especially those relocating for work or looking for a second home. The peak seasons for selling are typically spring and summer, as families want to move before the new school year begins. For this reason, many house-buying companies make an all-cash offer year-round, allowing you to sell your Charleston, South Carolina, property regardless of the season.
