Minimum is the fire and hazard insurance that a lender will require to give you a loan. Beyond that you should have liability insurance to cover your assets if something happens to someone on the property. Most of us on this forum are real estate agents and not insurace agents.
You should contact an insurance agent to speak to you about all the products oout there.

Jim,

Your minimum requirements for home insurance may depend on several different things. It may depend on the location of the property, whether or not it is in a flood zone, the age of the home, the age of the roof, electric, central heat and air. It could vary depending on whether there is a mortgage on the property or not. The mortgage company will require you to carry enough insurance to protect their "interests' in the property. They often also determine what deductibles are allowed on the policy. Check with your mortgage company on their requirements and then your best bet may be to check with local insurance companies in your area and ask what their recommendations are.

Check with different companies, as sometimes premiums vary. Be sure you also find out what rating the insurance company carries. This determines the strength of the company.

Best wishes!

I don't believe a realtor can answer these questions perhaps interview a few insurance agent.s
