Is positive cash flow a myth in today’s environment?

Hi all - I’m looking to purchase my first investment property near Houston. Single family home, relatively turn key, ~$250k, decent schools.   Given rates are what they are, I don’t seem to find anything that positively cash flows.  Is it silly to be looking at that as a factor?  I don’t want to do any significant renovation work with this being my first, and I don’t expect to cash flow significantly, but I am having a hard time finding anything that breaks even.  Maybe I’m being too conservative on my numbers, but I thought I would poll the group on whether this is just the nature of the current environment or if there are other things I am not considering.  Thanks!
