Multifamily vs Office spaces as CRE investment

[Ravi Arora]

Howdy folks. Newbie here.

1. How do the office spaces compare to multifamily (or living spaces for that matter) as investments? In my experience, I mostly hear houses or multi-family as the first and foremost cash flow investments. I am guessing that their popularity can be attributed to the fact that most people own houses and are familiar in operating those?

2. What are some good websites ( other than BiggerPockets) that offer calculators for performing investment analysis across asset types?

Thanks in advance for sharing your experiences!
