Vaguely remember reading articles using that # as a rough estimate.

There was also a recent article in NYT about some of the changes happening in Yonkers but it related more to downtown. 

@Chris You @Julie McCoy @Stanley J OkazakiI believe the info can be found at http://www.cleanairactionplan.org also check out the Port of Los Angeles.They revamped the site so I don't see the article I originally found.

can you post a link to the article 

There's a lot of information in this article (and even more so in the comments section) that might be helpful to consider-https://www.biggerpockets.com/renewsblog/2013/08/1...Ultimately though, you should always consult a professional accountant or real estate attorney to confirm any decision.

That was a really good article by Brandon Hall. 

When you say AirBnB you are limiting your marketing options like @John Underwood said.All homes are going to have different occupancy rates throughout the year based on numerous factors.

Consult with your attorney but I would expect your lease provides that tenant is in default for late payment, triggering numerous default options (acceleration of outstanding rent owed, right to evict, etc.) for you as LL.

Make sure to listen to all the BP podcasts, read the articles on the main blog and be active in these forums to learn a ton very quickly about any topic in real estate you want to know more about.This is also a great place to meet people that can be assets to your business.

Aaron here is an interesting article about the Cashman Center that is just north of downtown that just the Vegas council OKs transfer of Cashman Center back to city.
