What are your top 'Makers or Breakers' when analyzing a duplex deal?

[Steven Barros]

Hello BP Community,

I am new to investing and I looking to do my first deal, I have spent the last 6 months or so doing research, reading books, and looking at deals. I am curious what are some of your top 5 makers or breakers when looking at purchasing a duplex? I know some of my mentors look around for deals in neighborhoods with good schools, some are all numbers and high cash flow, and some of them avoid septic and HOAs etc...  Everyone seems to have their own niche thing, with that being said and being newbie I have not found mine.

I look forward to any advice

Thanks!
