It’s not possible to sell your house in just one day, even with a real estate agent. The process can take up to 30-90 days, as there are various legal steps involved in the closing process such as title search and settling liens. However, if you’re looking to sell your house quickly, the best option is to sell to a cash buyer like Sell My House Fast Greenville. We can close the sale in as little as 7 days, allowing you to move on with your life.
