Location is very very important but sometimes poor location can be overcome by great management.

My initial infant level of knowledge would tell me it's a combination of being poorly managed (I calculated they're spending nearly 65% on expenses to only have $305K NOI on 95% occupancy at $875/m, if that's even the average rent/unit currently occupied). 

For example, if a 1,600 sq ft main house is appraised at $100 sq/ft, what could I expect a 600 sq ft ADU of similar build quality to be appraised for?  

Quality VAs can do anything.

No formula can be accurate across the board because even “cookie cutter” properties next store to each other differ as to view, location to the street, topography of the land, lot size, physical condition of the property, past remodeling, quality of the mechanical systems, sunlight, utility bills, past use, etc.  

I specialize in single family homes in middle class neighborhoods , working people providing a high quality product for tenants that stay for avg. 5-10 years.   

And I put all quality materials and high end finishes throughout.

Hello everyoneI am relatively new to being a landlord and today I had very unusual situation that I don't exactly know how to tackle.I own a 3 story building with poor attic insulation and during the summer the attic gets very hot, since there is only one window the tenant can only have 1 AC unit that can't cool the entire place down.

But if you just operate without a permit, the county does a poor job of coming after you.

Hey @Ashley Wong,I don’t have much insight into Columbus or Tulsa, but I run a turnkey provider in Huntsville and can vouch for the area—for two reasons.First, Huntsville’s strong demographic headwinds have led to steady and sustainable population growth (+20% in the last decade), while the city’s abundance of high-quality STEM jobs—brought to the area by industry heavyweights like Dynetics, Boeing, FBI, Redstone Arsenal, Blue Origin, and others—have attracted numerous well-heeled millennial renters.
