Should I sell as a package to an investor or individually ?

Hello all, I own a half duplex that I currently rent out. Also has a garage that I rent separately. I am in the process of trying to buy the other half (older person, house needs a rehab). I am thinking about selling the both when I buy and rehab the other side. Would I be better to market it as an investment, both sides each would rent for $1100/mo and garage is $125/mo. Or try to sell them individual to owner/occupants. The side with the garage would go for approx $100k, other side a little less (no garage but newer siding,boiler). Possible investor deal at around $170k for both? Income would be $2300/mo. Thanks!
