If that's what you mean, I'd say the best thing to do is to be helpful.Those members who step up and help others out tend to build a reputation and derive business as a result.

I don't know about the "coming back to haunt you" comment, but I do agree investors should consult with a knwoeldgable CPA on this topic.Depreciation recapture can come into play, but there are several factors to consider such as: You are receiving tax savings today and then repaying with tomorrows dollar (and we all know the dollar will be worth less tomorrow than today), if your current marginal tax rate is at 28%, then the recapture tax rate of 25% is slightly less, and if the gain derived from the building is less than the depreciation taken, you may only recapture some and not all of the tax.

An appraiser can look at those net energy cost savings to derive value.  

Then you will know how your IRR is derived.

@May Emery it sounds like that FSS list is derived from credit data.
