There's no magic to any of this, just appropriate skill-set and mid-set.

There's not magic number if it's a SFR or MFU.You need to decide if Y O U are happy with the deal.IMO, 'managing CF' is about "what do I do with the income", not What CF do I require.

Trying to find a magic one size fits all formula or shortcut, and using it, is why many investors fail, and are then forced to overestimate on the side of caution, which rejects good deals, and screws up bad ones, still  misses the mark, and then they will criticize or call out those that are actually accurate...because accuracy can't be done.
