Tom, I've sold a lot of homes that were for sale by owner. We have a form that the seller will sign agreeing to pay whatever fee our buyer has agreed to under our buyer broker contract. if the seller does not want to (or does not have the reserves ) to pay the fee, my buyer pays it or looks at other homes. I let my buyers know up front that I will not hessitate to show them fsbos. Whey take the chance that they don't find the right place? If someone wants to list their home fsbo, I don't really care. If it meets my buyers criteria, I'll show it to them. What probably bothers a lot of us is doing a lot of prep work for sellers for a few months then they go fsbo. Again, I don't care if they disclose that they are looking into that possibility upfront - just if I've spent a lot of time working with the prior.
You do have a point, though. There is a lot of negative vibe. It really never fails, though, when our neighbors and friends try it, a lot of them will spend a lot of time asking us for comps, information and a lot of 'what do I do next' questions. We refer to them as our 'pajama clients'. The ones who call us at 11 p.m. and often 9 on Sunday mornings..
Also, a lot of people keep using the word 'realtors' like every real estate sales person is a Realtor. Using 'real estate agent' would be more accurates.
