You give all realtors too much credit. Most of the homes for sale right now are represented by a realtor. I see houses represented by realtors who “rot on the shelves” for over 6 months. If you mean realistic seller with the help of a good realtor, then I agree. But realistic seller and bad realtor or unrealistic seller and any realtor won’t resort to a fast sell. In this environment, it would “rot on the shelves”.
Why would there be no Realtor? You have people who need to sell and people who need to buy, realtor connect those two people and take care all of the paper works and putting data into the MLS. But the MLS is very lacking the way it is and should be free to the public with much more data open to the public, which the Realtor already have. I’m surprise Google or Yahoo hasn’t created something much better and free.
