Federal Taxes: Tax Deductions for Secondary Homes

Hi All. I own a home that my mother lives in. The house is deeded to me (via inheritance) and my mother pays no rent. There are expenses and repairs to this property that I, as the owner, pay for (my mother couldnt afford them, anyway). Am I able to do anything with these expenses on either the federal or state level? I own a separate property that has a tenant who does pay rent. Does itemizing for tax purposes lump all expenses together against all revenue together, ornisbeach property looked at individually? Thanks
