If the tenant is not communicating with you, that falls under the "tenant unreasonably withholds consent" clause and you can post a notice on the door at least 12 hours in advance. 

When inquiring with the bank or credit union regarding their equity LOC product I would first ascertain how they allow the property be titled (individual, revocable trust) before even initiating an application. 

Revocable )California is a community property state so even if the investment properties are located in common law state, the law of the primary residence still applies. 

My contracts allow me to provide materials with contractors consent. 

I worked at a bank where about half of the 5+ unit borrowers were sole proprietors/revocable trusts.

I certainly did not, and neither did the mortgage lender who  pre-qualified me.After closing on the HELOC  this week, I was reading through the docs last night and stumbled upon the Occupancy clause :"Borrower shall occupy, establish, and use the Property as Borrower's principal residence within 60 days after the execution of this Security Instrument and shall continue to occupy the Property as Borrower's principal residence for at least one year after the date of occupancy, unless Lender otherwise agrees in writing, which consent shall not be unreasonably withheld, or unless extenuating circumstances exist which are beyond Borrower's control"So I'm not sure what to do.  

If there is another lien on the property, I would recommend getting a deed in Lieu of foreclosure and a consent judgment.

During this period the debtor must obtain consent by the Trustee to enter into any financial contract that presents a liability or in acquiring any equitable or legal interests in other property.Bottom line, the court will allow the debtor to enter into agreements to expense funds for the necessities of a debtor, leasing a property at fair market rent, buying food, clothing, having a car repair or other costs of living.

If an "assistant" get their own log-in, I'd have to bet it's with consent and under the responsibility of the licensee who is a member of that Board

That contract requires the seller/lender's consent and that probably wouldn't be hard to obtain from your mother.
