From my experience the office property has been about the same as my multi-family investments. There are pros and cons, guessing volumes have been written about which is a better investment and why. At a high level the occupants tend to be there mostly on business days during business hours, which means fewer after hours calls. No kitchens and fewer bathrooms also mean fewer calls, which is great.
The length of the vacancy, and the cost to turn over the unit, are the other side. Multi-family is usually a quick turn around, some paint, carpet and rent it out. The commercial could mean significant changes to the unit, even structurally, to meet a tenants needs. The cost can all be negotiated, but the vacancy is longer and more expensive.
The leases tend to be longer, which hopefully minimized your turn over. That is why people swear by storage units, no toilets, minimal renovation if at all.
If you follow your vacancy projections you should be good, just make sure you are setting aside the money to handle a vacancy, it can be tempting to use the reserves for other investments, but you really need to have a deep capital reserve.
