Adding 2 car garage with apartment to duplex

[Nate Burnett]

Hi all,

Looking to see if anyone has done this. I have a duplex (3 bed 1 bath / 1+ bed 1 bath) and I'm currently looking into adding a modular 2 car garage for the duplex... in looking at some potential models I saw that I can get some with a 1 bed / 1 bath above. Is anyone familiar with the ROI we could potentially see with adding an additional unit? I'm thinking we could potentially get around $1,300/month for the 1 bed 1 bath unit. Trick is, we're looking to sell in 2 years so I'm hoping to see a decent ROI for us adding both the garage and additional unit.
