Yes you can capitalize and depreciate or, in some circumstances, expense as repairs and maintenance on your schedule E. Either way be sure to keep track of your expenses and receipts.
Also, something very important, was this house your primary residence prior to renting? If so, be sure to sell the house in the next two years after you move out otherwise you will lose the $500,000 exclusion you get when you sell your primary residence. If you are looking to invest in rental property long term I suggest coupling the $500,000 exclusion with a 1031 exchange to really save on your taxes.
My biggest piece of advice though is to contact a CPA and talk with them and explain your exact situation so they can best help you tax plan.
