This is a hard question for us to answer since every market is different. You should ask your agent for their advice.
In my market the buyers don't live here, they buy here as investments for the most part so there is a lead time required for buyers to find a property and plan to come to the area to see it. Spring is our prime season with the Fall being number #2. I usually suggest a seller get his house listed in December and that way buyers can find it online and make plans to get here to see the homes in late winter to early spring before the majority of buyers show up. But many markets are totally different. You can plan on most homes being on the market longer these day because there are fewer buyers than in years past. Seek the advice from professionals in your area or tell us where you are and those agents familiar with your area can reply.
