Buying a 2 condo package deal to ‘house hack’?

[Lynn Nguyen]

Hello! BP newbie here. I am moving from to a new state in a couple months and have been considering purchasing a home to house hack as my first jump into real estate investing.  Currently reading The Househacking Strategy to get started.  

I found an interesting listing for a 2 condo package deal, $180k for two 1 bd/1 bth 600 sq ft units with both units currently renting at $1k a month. Both units are within the same condo complex. 

What are some things that need to considered in analyzing a purchase like this for house hacking? Tax implications? Red flags? 
 
How does the tenant’s lease work when you purchase an occupied property with intent to occupy and house hack? 

I’d love to hear your insight and thought process.

Thanks! 
Lynn
