Market Analysis Process

[Sung-Yong Kim]

Hello BP, I have a question in regards to market analysis. My goal is to find a multi-purpose (duplex, triplex) home to purchase with each unit having at least 2 bedroom/ 1 bathroom/ and around 900sq ft. I would like to do my due diligence and find the average cost of recently sold multi-family units around the area I am looking at. However, not a lot of sold multi-families appear on Trulia and Zillow. Should I also be looking at single homes, apartments, condos, townhomes with similar criterias to my ideal bedroom/bathroom/size? What other factors should I consider when I conduct my market analysis?
