Question from new house hacker regarding analysis

[Gianna Letinski]

Hello BP, 

I am in the market for a first house hack on a duplex and I'm hoping someone more experienced might be able to offer some advice. I've found a duplex that has a long term tenant in the smaller unit and therefore I would have to live in the larger unit for the first year. My expenses would be about 1k per month while living in the larger unit. Once fully rented however, cashflow would be approx. 550 per month. 

The question is, is it worth sacrificing the high expenses for the first year to be able to have the cashflow afterwards? 

By the way, my current living expenses are 1400, so I would still be saving 400 per month for the first year. 

Thanks!
