You know Zillow and Trulia - they are not able to represent the actual MLS - at least I thought. You know that most agents pay a website builder to build their systems - Like Boom Town, LinkuRealty and the others... You know you are member of a Multiple Listing Service through your Board of Realtors? We pay the fee to be able to access the Real MLS - don't we? Or is it just semantics? That MLS supplies your "IDX" provider with access to listings so you can enable a search system on your website - that you had built for you. - (1 comments)
