same here, I ran mine and it missed what an appraiser said last year by $56,789.00 (under appraised)
missed room count by 4, lot size by 364 ft
maybe they just guesstimate
REal estate agents in the past did perform valuable services that a buyer/seller could not do for himself.
However, with the internet and evolving software venues, more and more of the "matching" aspect of buying and selling real estate will be done directly by the individuals.
Right now, the only reason you need a RE agent in the selection of property process is, one, you can't always get full access to MLS (that will change) and, two, you can't actually get inside a property without going through an agent.
More and more listings will go online, though, with or without cooperation from RE agents. And the ability to post extensive photos and virtual tours will reduce the number of homes a buyer actually wants to get into to view (IOW, many homes can be eliminated from the buyer's interested list upfront).
I have bought and sold a lot of property and simply resigned myself to RE fees as part of doing business. I have worked with some excellent agents. But very rarely have I felt I received value added to the process commensurate with what I ended up paying the agent.
