Owners cannot get them out and have no support from the court system.

Which will require a lawsuit and then the court to make the decision. 

you can't take them to court and ask for damages?

I doubt this individual would want to go to court over anything.

You can often find one by access online court records and contacting the landlord-tenant attorneys that appear numerous times.

That code section states:(1) “Prospective owner-occupant” means a natural person who presents to the trustee an affidavit or declaration, pursuant to Section 2015.5 of the Code of Civil Procedure, that:(A) They will occupy the property as their primary residence within 60 days of the trustee's deed being recorded.

Google’s answered varied from the county enforcing it, or needing a court injunction.

You can handle the eviction yourself if you have the time to learn the process (know your local landlord-tenant laws and follow them to a T) and attend court, otherwise hiring an attorney can be money well spent. 

Many will go into bankruptcy, people will be laid off in droves.I was visiting Thomas Jefferson's farm in VA a few weeks ago and learned that while he wrote "all men are equal" into the Declaration of Independence he also had 650 slaves working his lands.

Do not let people who have been in court with their past landlords, for any reason, in your property.
