Found 2 Properties I really like but need help with the #'s!

[Quandra Adams]

I am trying to run the numbers on an owner occupied duplex that needs a few things before it's livable for me. I am almost sure that I put the numbers in wrong a few times because I got 2 totally different outcomes. One was had a negative cashflow! I am so nervous as this will be my first time buying real estate and really just need someone who's not as emotional about this as I am to help me run the numbers. I think the problem comes in when I try to guess the ARV and repair costs. Looking for a someone who is can help with this sooner rather than later.
