Julia, this is a great question and one I've wondered about as well. Here in Greenville, SC I'm aiming to get 9% cash-on-cash conservatively on the first deal I found for my partner (am hoping for more like 11-13%).
We bought 401 Canterbury St. in Simpsonville, SC.
PITI is under $400 and I have it rented out for $835/month. We put 20% down, did a tiny bit of cosmetic work, and have an interest rate of 4.85 or so.
It may get me burned at the stake, but I am a fan of the 50% rule so I used it for estimating expenses. I believe it to be quite conservative. So if my cash-flow analyzer (a super-simple Sheets thing I made) shows positive cash flow of near $100 per month, I know things should work because the 50% rule is so conservative.
Just my opinion, but if I see a property that looks likely to get to 7-13% cash on cash, I'm all over it.
Unlike some folks, I'm not on the hunt for RIDICULOUSLY GREAT deals. I'm on the hunt to build a stable of 22 decently cash flowing houses and attain financial freedom.
Open to your thoughts!
