We're losing the train of thought here guys. The question Stephen is asking is, "is it 'fair'.....a response time of an hour or less?" Buyers take a risk asking for a reponse of an hour or less and sellers take a risk not responding in an hour or less. It's going to depend on each situation I would certainly ask the buyer's agent what is the immediacy of requiring a short reponse time. Are buyers on a deadline (i.e., travel), did the listing just hit the market and buyers are trying to eliminate competition? There are numerous scenarios to consider and most sellers do have work lives. Countless times when we've all written offers, the sellers have not been immediately available. In my opinion, yes, one hour or less is unfair because it is unreasonable. If it's an REO, I'd be laughing my head silly!
