I doubt your problem is price. People search within a price range, so most of the people who've looked (3 a week for 3 months is about 36-40 people) can afford your house, or at least come close enough to feel they can make a reasonable offer on it.
I'm not a mindreader, but when the people drive up, they have some expectation in mind--maybe from the listing, from online photos, etc. And they know the price. They come in. And then...something happens. You're not raising the price on them, so it isn't the price. But there's some sort of disconnect between what they're expecting (and what they're looking for) and what they're seeing. And whatever it is is significant enough that they're not even making an offer. Look, in today's market, some people have no fear about making low offers. But you're getting so many people, it's not likely the price. They're coming in, and then they don't even want to make a low offer.
Yes, you say the house gets "RAVE reviews." You'd be surprised at how polite people try to be. And I think the clue is in that statement "RAVE reviews as to what a beautiful house it is." Believe it or not, that's not the reaction you want. You want people to come in and be able to easily imagine themselves living there. They have difficulty seeing past the unique art on the walls, or the artwork you picked up during the 5 years you lived in Asia or Africa.
Get a good home stager in there. Get a straightforward evaluation of whether your home is staged properly. I suspect that's where your problem may be.
Also, while I'm not familiar with the technique of smudging that Anna refers to, I know a little bit about feng shui. Also, I'm a Third Degree Reiki Master--and inanimate objects, as well as animate objects--can benefit from Reiki. I know all that sounds a bit "out there," but Anna's correct: some houses just don't quite "feel right." You might look into any of those techniques. But first, consult a good home stager.
Hope that helps.
