I'd like to see something come out for the commercial real estate market. It's really hard to shop online (without paying a monthly fee to costar or loopnet) for access to information that is freely available.
Would you mind sharing where commercial real estate listings data is freely available? I've thought about expanding PadMapper to include it.
From the leasing companies. For example, if you go the CBRE site, you can view all of their properties there, via a software service provided by loopnet. There's definitely room to start another service by getting those listings out there to a broader audience.
