Hey Mike, I have 12-doors in Detroit and 3 of them are Section 8. 

Some of the damages include ~$7,800 of missing property, kitchen cabinet doors ripped off, a mangled chandelier, a damaged refrigerator, divots from a claw hammer in the granite, and urine and feces stains on rugs, furniture, and hardwoods from an unauthorized puppy.

I'm having to make some assumptions because there is missing info in your post, but it sounds like the flex space doesn't have a separate door to the exterior.

No studies other than there are none around like I'm looking to build. 20x30 "commercial" storage with a roll up door and walk through door.

There are other avenues to review but I agree past rental history is important (disclosure I have 15+ doors right now)If you feel bad for them then rent to them.My point is its corporate america and you are blaming the wrong person - you are blaming the corporation but you should be blaming the politicians who create an environment that is tenant friendly and sue happy. 

It is zoned for SR7, a single-family home, but is being sold as a multifamily home since the property was converted into 2- two entrances, 2bed/1bath per unit, separately metered electric.

Quote from @Kerry Noble Jr: Preforeclosures are best called or door knocked.Tax delinquent or code voiolationsPreforeclosures, Tax delinquent, code voiolations, probates/inheretence, quit claim deeds, water shut off are the best lists.Understand it is a volume game. sending out 500 mailers probably won't yield any results.

Typically play to balance fresh design with budget is to source new doors and paint the boxes to match.  

Hi Teahjsia, I’m based in the Seattle area but have a portfolio of 9 doors across Memphis and Detroit.

This gave us a clear idea of all the details we needed to know in terms of paint color, floor, and other key fixes such as windows, doors, and cabinets.
