Setting a price is both a science and an art and, in your case, it's got to have a lot more art mixed in with the science.
Even if "nothing is moving," that provides some (unfortunate) pricing clues. If nothing is moving, then the prices on those non-moving properties are too high for the current market and current buyers/lookers. In some cases, there may not be good comps, but some stuff is selling. Maybe no split foyers, but some ramblers, or colonials. In that case, you may have to look at those properties--look at number of bedrooms, baths, total square footage, amount of acreage, age, condition--and attempt as best as possible to adjust those factors for your split foyer. So, to use an extreme example, let's say a couple of 1950s 3 bed/2 bath ramblers on 1/4 acre lots have sold for $130,000. Yours is a 4 bed/2 bath split built in 1974 on a 1/2 acrea. Other splits have been on the market, not selling, for $225,000. Well, there's your range. Based on the size and age of your house, it's probably worth more than $130,000. Based on what's not selling, it's worth less than $225,000. Who knows? Maybe $199,000. Maybe $169,000. It depends on what people value, what they care about, and also what they can afford.
Hope that helps.
