What are some companies still insuring rental properties in Orange County California?

They usually have skiptrace companies that offer contact information if you have the address 

Something tells me you won't be working 4,060 hours to do so - 80 hours a week year round.If it is a more active rental model that it is not considered "rental" income, then you would need to put in at least 100 hours with that being more than anyone else (employees, contractors, management company, etc), or you would need to put in at least 500 hours.So your "quick" question is actually fairly complicated. 

They point to the company doing 30-40, which is directionally consistent, deals a month so you wont necessarily find it in any database.

Our company also offers full service property management, rehab, etc so a true one-stop-shop for OOS investors.

My concern is being able to find a company or anyone to help me do this.
