I kind of disagree with your realtor about having the market move the price, because you have a niche item. I would expect it to seller slower than a SFH is a suburb.
My current property sat on the market for 4 months because it’s just a weird mix of nice house and equine facilities. I snapped it up in a day and was thrilled to find it. If I sell I expect it would take even longer because I have significantly invested in the horse facilities, so now I have a nice house plus two barns/indoor/boarding business. It is going to take a special buyer to want exactly that (or be willing to pay me enough to be willing to sell it!) I could price without the horse facilities, but when that time comes I will want the premium of either selling to a horse person or subdivider (I am slowly being swallowed up by the city).
