I suggest setting up an advanced search by your elementary school, number of bedrooms/baths, and square footage. Advanced searches on my website can be set up to notify you via email when new properties hit the market and when prices change. This will help set expectations for your localized market. Listings on my website are updated every day and only include active listings. This video demonstrates how easy it is to set this up.
Understanding the list prices of homes for sale around you is a great way to get started. However, that is only one part of the equation for determining the best price for your home. You need to know at what price comparable homes sold. This is where a great agent comes in. Some people rely on internet sources to get this value. My research has found that internet sources are inconsistent and unreliable. A local agent understands the market best.
No matter how far out you are from selling your home there are probably things that should be done to prepare it. Get started on them as soon as possible. These articles might help you get motivated. Think about curb appeal and any items that need to be repaired. De-clutter your home and start sprucing it up. Check out the photos of the homes in your market area to see how your home compares.
