How much does price per sq ft matter when evaluating comps?

[Jaran Ramsey]

I am currently in the process of purchasing a Triplex right now,and based on the comps the averages are about $81 sq ft for that area. However, based on my offer I’m at $113 sq ft, now here is the catch this is the only Triplex in the area, and the only thing that is closely comparable to the Triplex on the comps is a 4-Unit that sold last year which SOLD at $75.06 pr sq ft. Is this sq ft something to really take into consideration? It’s kind of difficult when you don’t have a SIMILAR TYPE OF PROPERTY to compare the Triplex to based on the area. Thoughts?
