tenant moved out, not paying after damage repairs

[Steve C.]

Our tenant recently moved out. She didn't pay the last month's rent. 

So after damage repairs, she owes us close to $3000 after deducting from security deposit. 

What should I do in this case in California?

I see in other posts that go to court for small claims. Or hire a lawyer. 

Or just move on because it might not worth the pursue. 

Any advice or suggestion here? Thank you.
