Staffing is what will cause me to bang my head into the wall and cause a brain injury. 

I'd like to finish it with insulation, electrical, dry wall, treaded stairs, etc. 

The kicker is that the HOA put a charge of almost $5,000.00 onto my monthly statement .I called them on it, and the lady says that the board decided that they are splitting the bill between me and the neighbor with whom I share a wall on one side.

Commercial unit is not rentable, it needs quite some rehab to bring it back to a rentable condition (electric, plumbing, wall…)The property is priced significantly below the sum of the parts.

Their dog ($400 pet deposit) has chewed and clawed through multiple portions of walls and door frames.  

Also I believe you'll need a wall separating the actual bedroom otherwise it is considered a studio.

The concrete has been poured, exterior walls, window, roof is done.

This slogan merely means you can put down ZERO and the Investment will be NEGATIVE but if you buy it without financing it, you will Cash Flow.You make the Investment Cash Flow.Also, Cash Flow can be a distraction from much bigger problems.Buying a Property that you cash flow in a DEPRECIATING Local Market is a set up for failure.Take Detroit during the decades before it went bankrupt.You may have bought a Cash Flowing property decades before, but the writing on the wall was that Detroit was going to depreciate when the Domestic Auto Industry was a decades long slow train wreck.Detroit, at that time, was 90% dependent on Domestic Auto.There are 2 rules that I follow:1) ALWAYS buy in Appreciating Markets with a horizon of at least 10 years2) You (notice, I said YOU) SHOULD Make the Investment at least break even if not some positive cash flowIf you are in an Appreciating Market, your Cash Flow will grow.For instance, I am in Brooklyn, NY and my first investment was in 1998.My rents went up over 350% (from $1k for a typical 2 Bedroom apt to $3.5k today) over the 26 years.Not only do I cash flow from the Rental Price Appreciation but soon my Mortgage will be paid off by the tenants.The Cash flow will be HUUUGE in about 2 years from now.Many Investors here seem to not understand that Appreciation is BOTH the Investment's Value and the Rental Price Appreciation.

The downstairs tenant’s want me to spray insulation in the walls and ceilings as a way to mitigate the noise level and help with the heating costs.

(3 by 6-foot hole in dry wall; Garage access door complete broken off with damage door frame, the main entrance door way frame is broken and need to be replace, damage to the rear entrance door frame as well).
