Combine a Duplex Split into Two?

[Cody Cotten]

My wife and I bought one side of a duplex (basically a townhome) and are looking at buying the other side so we have control of the entire building. A benefit would be that we could paint the brick and generally improve curb appeal of both sides. Plus we could rent the other side out.  Long term we want to sell. 

My question is should we do this? I'm not sure if it is easier to sell just our side to an Owner Occupier or take on the other side so the entire duplex can be marketed to an investor.
