Am I overestimating costs?

[Kim Forgione]

I haven't done my first deal yet. I'd like to BRRRR. Also considering turnkey but don't like that I can't get my money back out. I have been analyzing a lot of properties but can't seem to find a deal that makes sense using 10% vacancy, 7% maintenance, and 7% CapEx. Am I overestimating these costs? I like to play on the safe side but when I use these %'s, cash flow looks pretty poor on the properties I've looked at so far.
