Over the past five years I have worked with hundreds of REALTORS on their web site. As we move from MLS to MLS, I've noticed a common theme, and I'm wondering if any of you have observed it as well... The more sophisticated / exclusive / expensive the homes are in a particular community, the less likely brokers are to share data thru IDX. The patch work of MLSes and the rules that we need to follow as web developers are hugely inefficient. Some MLSes, such as the Vermont Real Estate Information Network are fairly progressive about datasharing. We can post VREIN (11 comments)
