I know the cost approach data supplier issue has been hashed over before. But I am wondering if there is any difference between building-cost.net which uses data from Craftsman and the National Construction Estimator currently available for download from Craftsman’s web site for $44.99? Specifically, has anyone used both and is there any benefit of one vs. the other in terms of ease of use, data provided, etc.? Also, if you have used both, have you estimated the same property and did the numbers come out the same? I am as cheap as the next guy, but am willing to pay the $45 bucks if there is a benefit.
