Things to consider/ask about:
1. Replacement coverage vs. stated value coverage
2. Flood Insurance if needed - There are some new flood maps good to check on
3. Theft & Fire
4. Coverage for workmen on your property, pet coverage if you have pets, personal title insurance (attorney question) etc.
Hope that helps,
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.
