Thoughts on Mixed Properties? are they good investments or stay away from them?

[Gregory Martin]

Hey Guys, what are your thoughts on Mixed properties. For example a duplex with a commercial front store? I am new to real estate, if the numbers make sense should I consider buying one as my first rental property or should I only focus on regular 2-4 units? if 5-10 years later I wanna get rid of them how easy would it be? Any insights, tips or advise would be helpful. thanks
