What would knowing this information do for you? In order for an agent to help you accomplish your goals, they need to know why you want this info. What if the last 15 homes that sold there ranged from 1 million dollar McMansions to foreclosures, fixer uppers, or ???
If you are wanting to sell a house, the last several homes sold comparable to yours is what you need.
If you want to buy one, you only need to see the ones that sold in the price range and area you want to buy.
If you want to invest in one - do you want to rent it, or flip it?
Data by itself won't help you - it's the interpretation of the data by a professional, based on why you want it that will give you the answers you seek.
