Can I claim the deductible amount for an insurance claim on a rental property? I had a $3,500 hail damage claim and $1,000 deductible so insurance paid only $2,500.

You can claim as an expense for the repair of your rental property the difference between what it cost you to make the repairs and the amount your insurance company reimbursed you for the damage.  Example, if the repairs cost $3,500 and the insurance company reimbursed $2,500, $1,000 would be a repair expense on Your schedule E.
