Doing moded house hack - do normal metrics like cap rates matter?

[Cameron Mertens]

Hello! My gf, friend, and I are going through the process of starting a modified house hack on a 4 unit building in LA. We have been preapproved for the right amount of $ and we are looking at finalizing our agent and placing offers. It's modified because we will be living in 3 of the 4 units, so the 4th unit will just be offsetting some of our mortgage and the 3 of us will be covering the rest. Because of us occupying 3 of the 4 units for the first 2 years, do we need to take into account normal metrics for evaluating properties (such as cap rate) or as long as all the costs fit within the budget we have set for ourselves is it fine? Thanks for your thoughts!
