My blogger friend in Tucson, John Schneider, has an interesting post here, in which he compares Zillow estimates of value with the actual sales price. Zillow errs on the low side, usually. Does that apply to Greenwich? Who knows? I envy John because even if Tucson prices are much lower than Greenwich’s, he at least has some sales to work with. Oh! Waaaait a minute, …. much lower prices, more sales – could that mean ….. nah!
