Property sells year round. It is mostly a function of supply and demand, as well as other economic factors. The time of year you choose to sell can make a difference in the amount of time it takes and the final selling price. Generally the real estate market picks up in the early spring. The strong spring market often places upward pressure on interest rates.
Many prospective home buyers and REALTORs take vacations during mid/end-summer. The end of July and August often shows signs of slowing for real estate sales.After any summer slowdown, sales activity tends to pick up, although less vigorously, which usually lasts into November. The market then slows again as buyers, sellers and REALTORS turn their attention to the holidays.
There are still buyers in the market place, but now those buyers have fewer homes to choose from as the supply of homes on the market diminish because sellers often take their homes off the market for the holidays. Those homes on the market at that time have considerably less competition. Generally speaking, you'll have the best results if your house is available to show to prospective buyers continuously until it sells.
