I love how the two of you came up with the bar chart overlaid upon a city map to show the relative price per square foot. It's so intuitive to read and understand, and personally, I too believe this makes the most sense, rather than heat maps. Because, using a data map like this, prospective home buyers can look at 1) their budget -- how much total $$ they can spend, including downpayment, and then 2) their minimum sq foot requirements (ex: might have kids and need atleast 1,000 sq ft) and using 1) divided by 2) arrive at the Price / Sq Foot that they can afford. Then they can use your map, and immediately identify neighborhood within the neighborhood that are likely to have a place within their budget and sq foot requirements. Would be a great tool for potential home buyers. You could try this as a service in 1 city, and then turn it into a startup that services metros around the world -- Hong Kong, Sydney, Bombay etc - for a small 1-time or recurring fee. You could also sell the service to real estate agencies, who use it to narrow down neighborhoods for their clients based on the 2 criteria mentioned above. You get the idea. p.s. Please make one for San Francisco if you can :) :)
