Startup Idea : Neighborhood statistics and discussion

When renting or purchasing an apartment in a big city the most important thing is location. And the general advice is to do due diligence before making a major move. Think of a website with a list of all neighborhoods of the city which helps you with that, by providing some info like: - population density - number of public spaces - schools and their ratings - a discussion board - average cost of square meter of property - etc..
