Your concern about time on market for your home should be a concern if you are not already on the market. You need to do everything you can to shorten your market time once your home is out in the public eye.
1) Price it to sell. Do not over price your home. Many owners interview agents, get 2-3 opinions on price. Have the realtor show you the SOLD comparables used in their analysis and price it with NO ROOM to Spare. This way, that same analysis "could" be used to show a buyer that you have not overpriced your home.
2) Get your property inspected, (and surveyed if needed) so that all disclosures have been made up front. Also, from the inspection report, try to make the repairs. This will save time and will ultimately save you money. (You don't want a buyer making a discovery on any defect with your property, buyers and agents will multiply a cost of a repair by 10 or 100.)
3) You can get the paperwork together from when you purchased your home and your local Title company or have your listing realtor get a pre-determined title search done. (Should not have any cost here as long as you use that company when you have a buyer).
Have your Realtor do an Open House Immediately (the 1st weekend it is listed if possibly) and invite ALL your neighbors.
All of these should help shorten time on market, unless something is wrong with the home and your agent should be able to share with you any problem you might have to face.
Happy buyer hunting.
