Or should my tenants make all payments and contract with the LLC A that holds the property and then I subsequently make draws out of there.  2-If i were to raise money under the traditional GP/LP and the GP would be a newly created LLC that I wholly own and I also wanted an equity interest using one of the LPs, should the LP interest be owned by a parent company (Parent Entity LLC) or is it individually myself? 

I would be more inclined to let this property slide into either a mortgage or tax sale and take my chance then (if I thought there was potential for the property).

To answer your scenario the master coverage for the building covers the building itself and common areas SLIDING GLASS DOORS ARE a part of the building.

first tenant is usually free.. its subsequent years.. not many pm's I know release for free most have leasing agents they have to pay a commish too.. which most owners don't realize 

If they are under 20, then involving them in the development and subsequent day-to-day management (well, weekends and school vacations, really, when you are talking about a paintball place) of a Paintball facility would afford them an opportunity to learn how to run a business (and how to delegate and hold both themselves and employees accountable).

Then, as per the terms of the rental agreement for subsequent months. 

I decided to let that one slide for the time being, until I can get there IF it's still available.

In my experience things will be sliding downhill rapidly for now on. 

We initially signed a contract for asking price on the property and I subsequently asked for $20k break on the price based on the inspection results, which I thought was a fair ask and the seller signed the addendum accordingly.Now the seller is asking me for another $6k to cover costs of heating unit replacements (after further inspections done by the seller as required by the city) since the units are over 50 years old and cannot be brought up to city inspection requirements.
