Personally I have always presented an offer to my sellers no matter how ridiculous they are. I don’t really buy into the caviot that a realtor does not have to present a frivilous (pardonif I spelled it wrong) offer. Even if I simply make a phone call to the seller and give him the verbal details, I would much rather play it safe.
As far as being on the other when I represent buyers I also have no problem submitting an offer that my seller is comfortable with. If I feel that the sellers will not respond I do tell my client that, and I do let the buyers agent know verbally what the offer will be prior to sending it. In this market I don’t buy that line about sellers being insulted any more. It is a buyers market and sellers need to deal with it and/or their agents need to prep them that it is going to be this way for awhile. There is never any intent to insult, there are just people who are looking to mitigate their risk moving forward when they do buy.
