@Chris Morris have ALWAYS seen bad "deals" from rookie wholesalers that really don't understand what they are doing to provide value to the industry.It's getting worse because the real estate market has recovered from the 2010 Crash, yet many are still using tactics & methods developed during this time.Everyone in the industry needs to go back and look at what was being done BEFORE 2010 and start using those methods, updating them with current technology.

This would apply to your unit.Your biggest concern with setting the rent should be the near future. 1) Your insurance is guaranteed to go up, probably dramatically.  2) You may get an insurance assessment bill to cover the CA Fair Plan losses.
