A rate hike approved for Citizens Insurance will mean homeowners will see an average 11.5% increase in their multi-peril policy premiums by the end of the year. The average increase is actually more like 12.3% when all personal lines, such as wind-only and mobile-home policies are factored in. Commercial properties could be looking at an average hike of 10.2%. Insurance industry observers say it all comes about because Citizens is trying to return to being a true insurer of last resort.
