Trying to House hack!

[Zachery T Moore]

First time home buyer and wanting to house hack, found a great duplex for sale in a thriving little town that is off market! It’s a two story house that has been turned into a duplex, with the top half having its own entrance.  One unit is rent ready and been remodeled, the other half is livable just not remodeled. How do I go about trying to find comps with one unit being remodeled and the other not and if it’s at or below or maybe above market value on what their asking price is? Not many duplex’s in the area either that has been recently sold for comps.
