what's the difference between homeowner's insurance and landlord's insurance?

What's covered in the landlord's insurance not covered by homeowner's insurance.

A previous tenant destroyed our heater. Will that be covered under any of the two?

Thanks in advance for your time.
I'm in Guam right now. Property is in San Diego. Tenant was previously managed by an ex property manager. Tenant no longer there. I just discovered the situation when the new property manager asked a heating company for an estimate.

Well, the homeowners is for owner occupied dwellings, the landlord's policy (not a real insurance term, btw, so it's impossible to know what kind of coverages are there) is for tenant occupied dwellings. IN other words, the owner doesn't live there.

A landlord's policy covers the dwelling. Other coverages can be added – but are not built in. It's more of a cafeteria style insurance policy.

How did the tenant destroy your heater? Vandalism? Did you file charges? You have to file charges. If you're on a homeowners policy, and you don't live there, and the tenant vandalizes something, you could have an exclusion on your policy.

Heck, even on the "landlord" policy, you could have basic coverages – fire only. And then, again, it would depend. Did they set it on fire?

YOUR AGENT is the person to ask, both if the property is insured correctly, and if this claim is covered.
