A lot of appraisers will look at comps given to them, but they normally have much more access to data than most and data is king in valuations.

Looking at the data you have presented it shows you have a good asset that could either be hold as rental or sell to make huge profit now but before you take that decision to sell i would like you to consider how you are going to reinvest your proceeds from the sales, will that proceed get you superior or equivalent property asset at a better or same location for i know you definitely will not get that asset or something similar at the same purchase price when you first bought it.
