I am not really sure what your precise question is.

My passion for real estate is off the charts.

The tax rules change on a yearly basis, so if I don't personally have an S Corp or a Self Directed Roth IRA, I don't keep the precise numbers in my head. 

To be more precise, Denver’s STR policy applies to the entire City and County, not just downtown.

@Mark Gliebe, Imagine the chart as a one gigantic titanic ship with 24 floors and you are seeing a glimpse of a iceberg in Seattle (first MSA city to be in the red).

This will not exactly be as precise since I don't think zillow shows you "leased" listings; I believe they only show "active" listings.  

The higher depreciation deductions that a CSS will give you and applying that to your taxes might have an impact on your financing (or more precise with whom you are doing your financing) as it might show on your tax report as not making any money or, worse from the perspective on financing qualifications, as losing money with your rentals.

A great broker should be able to price this building more precisely, and not only take photos but actually help prepare it for market.

I know the price of the property and I can precisely estimate the expenses.

If it's true what your saying, holding is absolutely out of the question for sure and is precisely why I started this thread.
