The prices that come from Trulia, Zillow, or any of the real estate sites are computer generated. These estimates are not usually very accurate at all, since they do not take into account the features and uniqueness of your home compared to similar homes in your area. For a good estimate you should contact a realtor and they can provide you with a CMA (comparable market analysis). They will look at local similar homes that have sold and take into account of the features that your home offers and make adjustments accordingly to come up with a recommended price range for your home. I am a local realtor, and I would be happy to provide you with a free market analysis. You may reach me on my cell (717-599-0076) with any additional questions or to schedule a meeting. I would be happy to assist you!
