Hey @Matt C. and welcome to the forums! With that said, those "rules" are really not rules, they are guidelines that will help you quickly see if you need to look further into a property. The theory is that if a property meets the rule, then they should "theoretically" cashflow/make money. With that said, when you are new, you have to just analyze a lot and see what the actual numbers get you. Once you get the hang of it, you will start seeing things or finding homes that meet what you are looking for without spending too much time on them.
To get into any market, you have to be very familiar with a few things. What a typical rehab is going to cost (at each level: cosmetic, heavy, full), what closing costs/cash needed to close (roughly), and the ARV. Once you have those, you will be able to start seeing which neighborhoods to avoid or which ones to go full bore in when a house comes on market. Positive cashflow in markets like SLC, some parts of CA, Austin, etc. can be hard to come by in this crazy market we have right now but don't give up!
Also, don't try to go too fast. Make sure you have the cash reserves and everything in line to keep you going. This is a marathon, not a sprint! I hope this helps! Good luck!
