I am not an accountant, and would advise that you pay one to do your taxes, since rental situations add complications and there are a lot of ways to get in trouble.
But, You should be able to deduct all of those expenses. They will need to be prorated for the number of tenants at a given time... IE, If you lived there and had two rooms rented out, you would only be able to deduct 2/3 of costs.
Deductible costs include but are not limited to any repairs made, things purchased that were under the $500 de minimus rules, driving done to pick up materials and check the place out, renter screening costs, and depreciation.
For depreciation, you can only deduct the value of the structure, not of the land. What I did to figure out what my deductible structure value was, was to use the property tax assessment done most recent to when I converted to a rental. It had the value of the land, and the value of the structure. I calculated the percentage of the total assessed value that corresponded to the structure(s), and applied that to my house's purchase price + closing costs. Then you basically divide that value by 27.5 and get to claim it against your taxes each year.
If your MAGI is below 100K, you can claim losses on rental property up to 25,000 if you actively managed the property. I usually end up increasing my tax refund when I claim the rental income...
