AC filter, smoke detector batteries - do you change these yourself?  

Guessing they are blowing smoke...which would not surprise me in the least.

People who will actually show up to get it done and not be arguing with their girlfriends on phone, smoking dope, etc...Bahahaha!!!  

Of course he promises he’s not smoking inside...I’ve done a walkthrough of his place while he’s not home and wasn’t able to determine if he’s actually smoking inside..I’m wondering if there is anything I can do specifically to prove that he is/isn’t smoking inside?

The counter (laminate) is bent in the middle at the sink, and the supporting cabinets don't seem to be helping.Here is a remodel plan that imitates the original layout (has all the plumbing/electrical to support this configuration without modification):The sink (dark blue) counter is 9ft long. 

Do they smoke? 

My first tenant, however, violated the NO SMOKING policy and ended up burning the front of this building down two years later (another story).

Mike was being kind in his response. they are setting you up to pay your fee's up front then they will all of a sudden tell you your deal does not work and you money is lost or they just go dark altogether .. 

I decide on DST to avoid taxes.Feb 9th: I have smoke inspection schedule.

Am I blowing smoke or is that valid advice?
