., and the only reason they are broke is because they blow all of their money at the casinos, and on cigarettes and going out to eat or to the bars, etc.If you go ahead and raise her rent to market rent, she will cope.  

Dad and son smoking..

For example, in California, a smoke detector must be inside every sleeping area and must operate on a 10 year battery.

Bigger Pockets had a previous built lease that had some very strong clauses in it such as the smoking policy and turnover of keys.

Also, I wanted to hear their conversations to learn things about why they were looking for a place to rent, do they fight with each other, do they smell like smoke or pot, did they bring friends with them who are people I wouldn't want hanging around on my property, on and on.I know some people think having an open house generates a type of bidding frenzy, but you're still going to have to screen them.  

If you are willing to evict for this type of lease violation (smoking in the apartment), what evidence of smoking can you take to court?

I even had criteria that would get a tenant denied like: rude behavior, came with rude friends, showed up late without calling, missed an appointment, didn't fill out application completely after being asked to do so up front, smelled like cigarette smoke, had filthy car, just on and on. 

But during my inspection and walking of the place prior to close I can smell the strong odor of cigarettes and have seen the ashtray in his apartment.  

I have one I made which talks about credit history/scores, pets, smoking, evictions, criminal history, income requirements, etc.

Additional Thought:When you take possession do a Crime Free/ Drug Free Addendum for all tenants signed and returned in 3 days.Give bad tenant the 30 day notice to vacate.If you notice activity of drug smoke smell anytime in the 30 day notice to vacate period , give him a lease violation notice, that you will file for cause unless  he agrees to vacate within 7 days.
