We do offer bank statement HELOCs for business owners who don't show income on paper but can show revenue coming in(bank statements), doesn't sound like that applies here.Freddie Mac allows for assets to be counted as income, 70% of total divided by 240.

A lot of business travel, younger people in town for concerts, sports, etc. 

The only guarantee in the Rental Business is to get First, Last and Full Security Deposit.

and how do I go about dealing with this.Unfortunately this is business, some people suck.

Anyone who promises you an easy time of anything in this business is without a doubt looking to take advantage of you.4.

Is it as simple as setting up an llc on zen business or should I hire an attorney? 

Even if you create a non-CA LLC, if you are managing the business from California, you will likely be deemed to be "doing business" in California and therefore likely subject to CA taxes.

Good business relationship?
