Whether you are selling due to a job transfer, a newly empty nest, or a new baby, it's crucial to list your home with a local Realtor. Every local real estate market has its own unique culture; a Realtor unfamiliar with your area's customs and quirks and will be at a disadvantage.
For example, I deal often with Glen Ridge and Montclair real estate, so I am thoroughly knowledgeable about the Montclair real estate culture. Standard practices here include delaying showing a property until after the Realtor Open House, and holding a Public Open House on the Sunday after the Realtor Open House. We also generally use GSMLS (Garden State Multiple Listing Service) lockboxes, so that the owner does not have to be home for each showing. If a property garners multiple offers, these offers are typically due on the Tuesday or Wednesday after the Public Open House, and they are delivered to the seller's agency in a sealed envelope.
In my years as a Realtor, I have seen numerous houses sit unsold for months on end. Often, the homeowner has listed the property with an agent from another town, or even another county. Don't make this mistake; only a Realtor from your community can present your home to its best advantage.
