Determining ARV with odd comps?

[Xai Xiong]

What do you guys think of a duplex with comps that are closer that differ in less bed/bath to be higher value than comps that are more similar further away that has less value comps? For instance, the duplex next door to subject property is a 3/2 duplex no garage sold for 325k and a duplex 6/2 more than 1/2 a mile away sold for 300k. The subject property is also 6/2 w/2cargarage. Additionally the subject property is a split foyer while all comps are bungalows. There is also a duplex 1-2 blocks away from the subject property that sold for 380k (4/2/2). How would you determine ARV? I hope this makes sense.
