Is it recommended to have a LLC and who can help creating a LLC (tax consultant or lawyer)? 

Not being familiar with California laws I would advise consulting an attorney to attempt to either raise the rent if possible or to evict.

This is typically a requirement for maintaining good standing.Record Keeping: Maintain meticulous records for each LLC, including operating agreements, minutes of meetings, and financial records.You should probably consult with a CPA or attorney just to make sure you meet all compliance guidelines.

Expect to pay even more if you're hiring them as a contractor/consultant rather than an employee. 

Always consult with your attorney before you rely on the above information.

So check your operating agreement and consult with an attorney knowledgeable with Delaware law (or whatever state it's incorporated in).

I will consult with a CPA and do my homework.

Always consult with your attorney before you rely on the above information.

Don't get me wrong, there are some great VAs out there, but you have to find them, train them, monitor them and pay them well for them to produce anything above mediocre results. 

Examples include BuildZoom and Zonda (formerly Hanley Wood).Property Records and Permits: Monitor building permits and property records.
