When the homeowner combines the home insurance Maryland coverage with other policies, the insurance company collects more premiums and spreads the risk. The homeowner may combine this insurance with coverage on an automobile, boat, RV, snowmobile or motorcycle. Insurance companies are betting all the items covered under one policy will not have claims at the same time. It is much easier for the policyholder to deal with just one insurance company. Homeowners know no matter what happens they only have to call a single agent to report the problem or make a change.
