I have a Google Form that I'm using for initial screenings that ask four of our biggest questions (smoking, income, etc.) but I'm not sure where to go from there.

The floors are currently painted dark brown.

Soaring highs in the sky and lowest of lows into pitch black darkness.

@Matt McGuire what's the lease say about smoking?

Thanks, and, Holy smoke, yes on the lessons learned part. 

Especially if you could go find a smoking deal! 

@Mike Kirby Likely incense or low quality candles that produce too much smoke .

Most of the NNN available with the down payment I have and ability to purchase in the 800k-1MM range are Dollar General type properties in rural areas that will have little to no value once they go dark.

I am 100% no pets, 100% no smoking anywhere on my property...It makes picking a tenants easier. 

Could be as small as a dead battery in a smoke detector in the middle of the night (no guest wants to hear beeping while they are trying to sleep), guests can get rowdy and disturb neighbors, I have even had guests that insisted upon having someone meet them face to face when they arrive.
