Hi, Start by calling some of the big companies, Allstate, State Farm, Gieco and get quotes from them. They will need an address, or at lease city you'll be buying in, value of personal possessions, any special items; i.e. guns, jewelry, collectables etc.
Agents at these companies will give you a good overview and sales pitch for their company. Set some boundaries as to what you want, low, med, or high deductable.
Before you purchase a policy, speak to a local insurance broker who represents multiple companies to see if a local company may be more competitive.
I hope this helps get you started.
