I would think if the price was too high that people wouldn't be visiting it at all.

My experience in buying & selling houses has been that when there are lots of visits, but there are no offers, is that the price is too high compared to what else is available on the market. What feedback have you gotten from the agents whose stacks of cards were left? Have they said that the price was too high? Or was there some other reason that their clients didn't make an offer? If your cut-price broker isn't getting feedback for you, then you need to get on the phone and call those agents that left the cards to get their feedback yourself.

I wish I had some idea of the direction home prices will take when rates go up. To me it would seem that it would bring them down further.

Well, you have some experience with increasing rates since you put your home on the market in October. From http://mortgage-x.com/x/ratesweekly.asp it appears that after an initial drop, rates have mostly increased:
