I am possibly moving to Dallas, Texas, in the next couple of months, and I have been looking around at the real estate market on that side. I’ve been really impressed by quite a few APIs, applications and search engines that have sprung around the real estate market. It seems to be a very exciting area in terms of APIs, visualizations and software, I suspect because the data has always been there and has been captured and analyzed to death, now its time to rework the interface.

Anyway, I came across this very interesting visualization called Hindsite by an real estate search engine called Trulia. It is based on public property assessor records for properties in Trulia’s database and typically includes the date that a house was built. Check out this amazing visualization of the Dallas/Fort Worth area, specifically Plano. It is certainely making searching for a house a whole lot more interesting.

Real Estate information and mapping are ideal partners for a mashup, and besides using Microsoft Virtual Earth for Hindsight, Trulia has a very strong integration with Google Maps for their search engine. All around a very nice application. And they even have an API.
