If it is in a desirable location, in excellent condition, is priced competitively, and is not one of a gazillion homes just like it for sale, it may very well sell quickly. If there is a lot of competition, if the home is not in as desirable a location, if the home needs more work than others, if it is priced higher - then it will increase the time on the market.
I have had homes sit on the market for months; had others go under contract within two weeks. All depends on how desirable it is on all key points: Location, Price, Condition, Supply& Demand.
It can vary quite a bit, and each market is different. If you price your home competitively and Stage it, it should sell quicker than the competition. Market time also varies according to price range. I have an absorption rate chart that I used for my clients showing how long it could take to sell their home based on price and number of homes on the market currently in the same price range. Hope this helps. If you need anything else, I'm happy to help you.
