I suspect most people on this forum don’t have use for a realtor. However, this is the exception, not the rule.
I don’t need one. You don’t need one, but most do so REs will be around for a long time. The HelpUSell model is not so bad. I think they will be fine, but even with them, you have a realtor working for you and they need to be good at what they do.
REs aren’t so helpful for the “do it yourselfer” type but the amount of time a realtor can save a busy professional with limited time is quite significant.
