I must admit I don't understand all the hatred of ceiling fans either - my house is only a few years old and well insulted/eco built but I still purposely put low level white ceiling fans in all the main rooms.They are more ecological than air con, and I think they look nicer than the normal electric plug in ones (they also remind me of being on holiday abroad when combined with decor like white walls and warm wood floors!). I can't stand being hot, so they are used most of July and August and the rest of the time I hardly notice them, they are just normal lights.
Anyway OP, unlike some pp I'm not sure that the price is the major issue at the moment (your lower guide price seems fairly reasonable for the area and you are getting the viewings.) I can only think the house maybe looks a bit unloved in person, and that's why you aren't getting the offers?
Before reducing the price too much, I'd try cheap things like finishing any small jobs that could psychologically be putting people off (like touching up or repainting any chipped/faded paintwork in the house or discoloured grout in the bathrooms, powerwashing the drive and weeding the rear patio, mowing the lawn and perhaps repainting the fence etc).
Then try "dressing" slightly for added appeal by putting bright plant pots under the front bedroom window and on the rear patio, rearranging the beds in the bedrooms so the headboards are against the walls (but not under the windows) so the bedrooms have better flow, removing the kitchen carpet (most people don't want carpet in kitchens, what is underneath?), and de-cluttering the bathroom. This can all create a more harmonious feeling quite easily, without major work or money. Good luck!
