ummmm no. depends on a lot of factors. are you in construction or real estate?

firstly MOST 60 houses have NOT appreciated. secondly the ones that have are usually PROPERTIES that have appreciated, not the buildings. lastly for the buildings that have appreciated, the majority have had work done. like my home, that i converted from a single story ranch to a two story colonial.

on what basis do you determine "at least 2x"?
