Best Software Tools for Analyzing Markets Remotely

[Reid Griffith]

What are the best websites, software, or tools to analyze data for the purpose of real estate investment? (Long term) Interested in the basics for a market such as average rents, property costs, average days on market, info on how many properties are being rented out each month compared to how many are on the market. Population and employment info as well? Doesn't have to all be on the same site.
