Recently I was hearing horror stories of how you may buy land in India and realize that you paid money to some guy who did not own the land to begin with..for more information see all the checks you have to do before you buy land.
Would it be possible to build a service that checks the title deed of a given piece of land, encumberances etc for you ( maybe scans it keeps it in a repository and sells you the scans for a price) . In addition reports on the quality of roads , conveniences nearby..and real driving times to important landmarks.
Like Google Maps changes its algorithms for India, an Indian Zillow will probably have to do some similar tricks...and given the market in India should have decent traction..
Is there a service like that already ?
