House valuation estimates normally take into account a number of different factors. If you are going to use a house valuation service then you will need to get one from a professional Chartered Surveyor who has years of experience in this area. These professionals will have access to accurate information, which they will use to give you a fair idea of what your property could be worth. The majority of companies who offer house valuation services will offer a free home valuation estimate and will always request a full description of any potential problems that may appear with the final valuation.
