The WLB lease (unless you use an ancient version) states that if nothing is done it defaults to a month to month.You can send them a Notice of rent increase (which you can get from WLB as well) sign an new lease, or do nothing and go mtm.I find that a 60 day notice from the tenant is not very helpful, most owners don't start showings until after the unit is vacant, so what's the point?

They seem to have a good business model and one of the owners is an investor himself which is definitely a plus, but they charge a leasing fee (to find and get a qualified tenant into the property) equal to 1 month of rent, which comes out to an additional 4%-8% on top of the monthly 10% maintenance/management fee depending on how long the tenant stays.

One thing I’m not able to find, is if I as an owner can take draws from the company and if there are any restrictions.

Well, that they can find a broker will let them which unfortunately if one look's around they will easily find a "home" that will let them do whatever. 

It has worked out well, but with this base we are willing to take on more risk/leverage in order to find more opportunity.

This should have come up in your fact finding when choosing to add the JADU (as well as their poor valuations)Note if the unit is only 2 units and you are abiding by the owner occupied rules of a JADU, AB1482 (statewide rent control) does not apply.  

How did you find this deal and how did you negotiate it?

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.PM us if you’d like to discuss this logical approach in greater detail!

I would find a handful to interview.

Going into a house and finding clothing and all sorts of things strewn all about the house in piles on the floor often covered in filth seems to be a normal way of moving.
