House Hacking Numbers

[Paul Honen]

Looking to house-hack a triplex in Chattanooga TN, where the numbers are showing me paying/reserving a little more than half my current mortgage (889) while I'm staying there, which comes out to about 544.92 that must be paid/reserved each month, but once I move out and get it fully rented, I'll be making 186.69 per door (560.08 overall) per month.

I was coming into house-hacking hoping to get my entire or at least most of my mortgage paid for. Am I allowing that hope (of being mortgage free) to cast doubt on a good investment overall?
