However, my heart is with real estate investing- so I ended up brokering where I invest, as I have a huge edge in knowledge over the average broker in the Capital District.

This class of buyers purchase the properties for reasons other than "income" (i.e. good school districts, desirable locations, emotions, etc).In your Baltimore property example, if the "comps" support $200k, obviously you would list it at $200k.

For the house, school district is important as well as lot size and privacy.

Be in best school district, best part of town, and pay close to to my current mortgage ($820). 

I was on the strip for a while but am currently at Therapy in the Fremont East District.

Also, check out the general district court, it's free! 

He has four identical townhouses in the downtown district that he has been AirBNBing out himself very successfully for the last 5 years.

I am in Harris County Texas, more specifically the city of Katy,TX where public works, school districts and such are part of the tax bill PLUS additional fraction of a percent directly to the city.The appraisal district has a particular portfolio of properties all assessed at significantly lower than what like property potentially would be valued at.

Then I looked on the Harris County Appraisal District by his name and found not only where he lived, but 3 houses on one street in the neighborhood in question. 

Steady population growth, solid local economy, developing central business district-- all new downtown convention center coming soon.
