As of right now me, my partner , and one other person is moving in but, I need to find a way to fill in the other 2 bedrooms.

No personal income, tax returns or DTI to worry about.

I would personally feel better if they were at 4" though, particularly if there will be small kids as renters.

It sounds like you are placing into service as a rental a house that was previously a personal residence.Your basis is purchase price + improvements made to the house from purchase to the time it was converted into a rental.
