Price, Condition, Location, Supply, Demand will all dictate how quickly your home sells.
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.
