Couldn't find any property with CoC ROI in positive tritory

[Samuel Gebretnsae]

Hi, I am new to real state business, I leave in California, and I want invest in rental property, so I am learning all the way through BiggerPockets, podcast, forum and books. Since I am remote worker, I can invest pretty much anywhere in Big Cities, to start I am taking Dallas as a target. So I am activity looking property in Dallas to the price range of 600K, I was running every potential property through Bigger Pockets "Rental Property" tool, and to my surprise every property I got have CoC ROI in negatives. Does this mean, now it is bad times so I need to put a break to my rental property ambition, with Inflation I know my saving being in Bank is not good also, but at the same time, I don't want buy property that doesn't have cash flow and am not sure it will appreciate either ( as people are talking about housing market crash or correction). Even thought I am seeing negative CoC ROI, all those properties are being bought after couple of weeks ( most after over 20 days on market and couple of thousands price cut, which doesn't affect CoC ROI much), I wonder what is the plan of those investors that are  buying those properties which is clearly not gone make them cash flow ? Are they betting on the appreciation?
