Which App/Website is best use to track most selling area

[Ken Hori]

Hi everyone,

Does anyone knows where/how  to get accurate information on finding the most selling area for real estate properties? I’m looking for some tool/app that will help me to find how many properties were sold (plus the final sell price) of each state in a list type of top selling area and bottom selling area (within the state) is it exists? I will appreciate any help. Thank you
