5First tenants decided to move back south after they witnessed a murder in broad daylight on the next block over.

Have seen the full spectrum of good to bad and what can turn into a total Sh*t show practically overnight.

@Dean Letfus war zone n.noun An area in which military combat takes place.An area at sea in which ships are prone to being attacked during a war.orDefinition of WAR ZONE 1: a zone in which belligerents are waging war; broadly : an area marked by extreme violence 2: a designated area especially on the high seas within which rights of neutrals are not respected by a belligerent nation in time of war I live in Memphis and none of my properties are in areas that I consider "WAR ZONES" if you say "socially and economically underprivileged areas" I would agree with you but definitely NOT "War Zones"..See below...

@Michael BishayYour question is too broad to provide any meaningful answer.

I've had tenants from both ends of the spectrum, though--and I can say from experience that happy, highly-qualified tenants make property management 100x easier.Now that I'm firmly at the bottom end of the rent market, with highly satisfied tenants (who are unlikely to leave), I plan to begin yearly rent increases going forward, starting this year.My target is 2.5%-5% rent increases every year for at least the next five years for renewing tenants.

Short answer--legwork and having a broad and active network. 

You aren't going to get any great answers here with a broad question like that.

That's about as broad of a question as you get.

Pretty broad request without knowing what real estate asset class you're interested in.
