Does 0% Vacancy Sound Fun?

[Sam McCormack]

What seems more appetizing to you? 

- SMF, 200-300k, in C- to C+ area , immediate cash flow (5-8% ROI), 3% appreciation/year, and 5% Vacancy

- SFH/SMF, 400k+, in B+ to A- area, break even (for the first year), 6% appreciation/year, and 0% Vacancy (EVER, unless you want it)

What seems like the better investment to you?
