In my opinion, even before I became a Realtor, it makes the best sense to use an expert to help you make an important real estate decision. In real estate the experts are the Realtors and heres a bonus...........its doesnt cost you anything!
Oh yes, no disrespect to the websites you named but, their goals are the same as with all companies in the World....to make money to pay their employees and their bills.
Its best to use an expert who can help you narrow down your choices quickly and with accurrate information. Driving around and perusing websites is very time consuming and does not always give you an accurrate picture.
When you get tired of spinning your wheels...call a Realtor.
