Let us know what the application fee, or the "lock in fee", or the "whatever scam name they call it fee" is.

My question is whether or not forms like a pet addendum, rental application, carbon monoxide/smoke detector acknowledgement etc. are state specific - I know the residential lease is subject to certain state regulations and will be asking an attorney about it.

You would need to see and confirm proper accounting of the contract balance and application of the payments.  

I need to make an application at this point and have her fill it out, as well as the first guy, and move forward trying to help these folks out.Then I need to verify how I get the lien on the homes.

Say if I buy in the City of lemon grove in the county of San Diego, my rate would be the County 1% + City 0.13% (ballpark sample, didn't look up actual) + sewer (if applicable) + trash (if applicable).

It sounds like the units are currently vacant so I would also strongly suggest you do not close till all units are rented (assuming you have vetted the tenant applications with the PM team) or get something in writing from the turnkey operator stating they will pay you market rent for X months while they get it leased out should you close prior to the units being fully occupied.

I was wanting to get your opinion on branding and marketing.I have two websites, one for our Real Estate Business, which is used for the property management side of our business, which has our available properties for rent, applications, testimonials, etc. and another site I created for "We Buy Houses".  

We do not have previous applications from the tenants.How would you handle this?

I've been reading through job posts, and the common one seems to be MS Office applications, but what are some others that I might be missing?

You can raise it, but it sounds like you'll have a wider pool of qualified applicants to choose from at the posted rent and possibly find one sooner.
