Cap rates across the country

[Dante Devine]

Hello BP, fellow investor located in LA looking for good multi family deals. I have a question. Can't one look at average cap rates across the country and make a pretty good decision on where they should invest? Cap rate is pretty much your ROI if you were to buy all cash right. So since financing is pretty much standard across the country, your only other variables would be taxes and insurance. All other variables were accounted for inside your NOI. I can simply choose a market based on cap rate if cash flow is my only objective. Please let me know if I'm looking at this wrong. If I am on the right track, where can I find a good source that lists cap rates by city?
