With plenty (90 days or more with an initial "head's up") of notice, I first "non-renewed", then moved out the undesirables, then made sure the vacant units were clean and functional, not doing any upgrades. 

Assuming there are only 3 categories:Class A would be Upper Arlington, Dublin, etc - extremely desirable by allClass C would be the Bottoms, South Linden, Driving Park, etc - undesirable, lots of crimeClass B is somewhere in the middle.

just wanted to get some other than my own insight on warzones. what makes them so undesirable to most investors. i think they are gold mines that are misunderstood and waiting to be tapped. a lot of buildings in war zones i notice end up becoming a city burden when the original owner can't afford the building anymore.

Just wanted to do a preliminary one myself before I paid for one just in case I decide to cancel a contract due to something like a major lien or even an error on my part (such as repair estimate) that might make the deal undesirable to an investor.

hes involved peripherally and is the owner but day to day operations as far as finding , offering, and managing the rehab is handled by mei would appreciate any input as to how to streamline this process to make the offering not so time consuming 

Areas that have traditionally been undesirable are transitioning.

In addition - for our brand, we're developing technology in-house that allows us to screen renters based on a number of factors that keeps undesirable guests out (or less likely to sneak in) reducing overall cost-of-ownership. 

-------We once bought an 8-plex that was occupied by some undesirable tenants (a stripper who had frequent late night "guests", pit bulls in two units, a single mom who couldn't afford the rent, smokers, and a guy who had lots of cats).

I realize this question is only peripherally related to real estate.  

Shreveport can go from desirable to undesirable in the space of two blocks.
