@Daryl Anderson I found a list of specific class neighborhoods through an article on here by @James Wise. It was form November 2016 so the list below might have changed since then. With that said the areas below are where I have been looking. Feel free to tear it apart or give specific areas where it would be a no go!!
@Account Closed I read through your profile and I must say those projects are impressive with a quick turnaround! Also good to see that you come highly recommended from James can rehab to rent and rehab to flip whereas some seem to get those two intermingled. I have not booked the trip yet as I am trying to get my points of contact setup prior to my visit so my time is well spent with appointments all day everyday I am there. Hopefully within 30-45 days that will happen. Preferably sooner.
