Mobile and Manufactured homes can be hard to get insurance on but the good news is that Amica does insure manufactured homes and mobile homes.
When I had a mobile home I had a hard time finding any insurance company that would insure my mobile home but Amica insured the mobile home without a problem.
Amica insurance company offers and sells comprehensive coverage for manufactured and mobile homes as well as regular site built homes as well.
I never had to use the insurance thankfully but from what I've heard from other people the Amica insurance company paid out on the insurance claims on time and without any issues.
