With any investment, I plan to conduct due diligence of the Sponsor and ask as many questions as I can (and plenty of people here have laid out helpful questions to "grill" a Sponsor with).  

see this smoker/BBQ?

Is that like outdoor smokers? 

In my mind if it included like a refrigerator than I am responsible to keeping it functional and repair or replace it when necessary.Complimentary is when it is an extra that the tenants may use, such as a bbq grill, a kayak, a shed...if it breaks, gets stolen, it is at my discretion and I may or may not repair or replace it, but I don't charge extra for it.Is complimentary the proper word to use in this context?

Can I prohibit smokers from renting one of my apartments, or ask if they are smokers when screening tenants?

Others will grill you about locks, dogs, updates, etc.

The other was a smoker who accidentally set her own sofa on fire. that one has an installed fire suppression system so her's was the only unit damaged and she agreed to reimburse us the damages (over time of course).

I've had a property trashed this way by smokers and their pets and I did need to replace the carpets, but just treating the walls with tea tree oil, then a bleach/water mix, then primer/sealer and paint took care of everything.

I recently purchased a condo that was previously owned by a cigarette smoker. 

Right now out of seven units I have four smokers, all of which claim to be 'outdoors' smokers, two of which I discovered subsequent to leasing.
