Would it be smarter to start house hacking and then go to BrrrR or start first with brrrr and then go house hacking?

My plan would be to get a duplex for me and my wife and use the rent from the other side of the duplex to pay our mortgage. After that I would have around at least 15k saved from not laying the rent and from the I would start brrrr. Would this be smart or what are the thoughts?

And for brrrr how can I get a private lender and use the bank to pay the lender at the same time? That’s what gets me confused about the brrrr strategy.
