I really have a hangup on estimating…
i think the prices they give are a bit high. you should talk to contractors not the ones in the yellow pages, but contractors that work with real estate investors you should get a lot better deals then some of prices they estimate on this web site.
there estimate for my typical kitchen and tear out is 9500-11500 my actual costs are $4000-4300 so they are a bit high
Now did you use ecomomy?
