The answer lies in your motivation and/or the reason for your sale. It seems to me that you are not completely confident that your home will sell within your desired time frame. Are you thinking of "testing" the market with anticipation of a price reduction or two? This is a huge mistake. You want your home to be at it's absolute best when it hits the market becasue there are lots of other homes that buyers can go to if yours does not grab their attention.
Analyze the factors that go into the successful marketing and sale of your home. In my opinion, the agent you choose is the most important factor in a successful sale. Does he/she have an aggressive marketing program that analyzes your home (both strengths and weaknesses) and where it fits into our market. Putting an ad in the paper and the home on the MLS won't cut it. Look at his/her sales history. Did you know that the MLS has data that can easily be pulled which allows you to look at an agent's listing history (any agent for the last 11 years)? Ask for it and if the agent can't provide it or worse yet, doesn't know how to provide it, that might tell you something about their ability to sell your home.
I would look at your home; location on the street, amenities and upgrades, schools, staging, to help in determining a pricing strategy that works for you.
You need to make the marketing effort so complete that you shouldn't have to have a price reduction. However, you also should have a plan in place, should you need to reduce the price (i.e. if it doesn't receive an offer within xx days, then the price is reduced xx amount). Starting your marketing efforts with the assumption you'll be reducing your home's price is a self fulfilling prophecy. Do it right the first time, be smart.
