House Hacking help please

[Robert Andrade]

Hey Y'all

Im looking at a duplex that has potentially great #s when both units are rented but if I house hack for that first year or two there's no way to make the #s positive.

cash flow of -$255 and CoC ROI -52.5%

once i move out and rent the second unit I'm looking at MCF of $460. and CoC of 54.99%

of course these aren't hard figures but probably pretty close. I'm using the BP rental property calculator 

does this make sense? Is this typical when hacking?
