There was a fire at the house next to one of my rentals that has damaged the siding on my property. We have been unable to reach the owner of the property. Is there a way to find out which company has insured them to make a claim on their insurance. The damage is significant but still below my deductible so claiming from my own insurance is not possible
You should still submit a claim on your insurance. They will find out who your neighbors insurance is and push the claim to them.
As long as the other insurance pays (or you end up paying since it’s under the deductible) it should not affect your insurance rates.
