I would avoid Memphis due to crime issues.
Any large city is going to have crime issues. I have lived in Memphis for 43 years and have never been a victim of any crime (except for having my glasses stolen out of my unlocked jeep once), my family has never been a victim of any crime and my friends have never been a victim of any crime. Yes, there is crime, yes there are large parts of the city to avoid but that is exactly what you do. Don't live in the bad parts of town or hang out in those areas.
