According to Thomas Aloysius, the best time to sell is determined by the status of your property's location. The house might sell in as little as 30 days in favorable communities. It may take longer in colder markets, rural areas, or selling a high-end property with a small buyer pool.
Your realtor should educate you on the average amount of time a house spends on the market in your area and give you an estimate of how long it will take to sell your home. Then they must do everything in their power to meet that deadline.
