Hard Decision for me trying to figure out my next move

[Asa Akuley-Strambler]

i bought a multifamily for $180k and i am house hacking and cashflowing $120 per month, I have $7k cash, should I use it as a down payment on a $60k loan to turn my 1000 square feet basement into a 1 bedroom apartment and stay down there and rent out my old floor (that puts me at $240k for a 3 family, top floor $1500, second floor $1250, mortgage $1,379 plus the $500 per month payment for the basement loan)? or should i use that $7k as a down payment on another fixer upper not exceeding $60k through hard money lending and do the BRRR method.
