Starting out with commercial real estate?

[R S]

I'm hoping to make my first investment purchase soon with cash flow as the goal. I had planned on either doing a SFR or condo but recently had a crazy idea. I'm considering purchasing a 1200-1600 square foot office condo and then building out 4-5 "executive office" suites of 100-150 square feet each. I would outfit each with a locking door and then lease them out individually to professionals who need small single or two person offices.

I think this has the potential to create more cash flow than an SFR or condo in my situation and spreads the risk of vacancy nicely. Has anyone done this?
