The bank is correct in that the HOA is considered an expense, however, you will most likely not get a refund check from the IRS. When you own rental property you will have to report the rental income using Tax Form 1040 - Schedule E. You can do a quick internet search and see the typical expense categories (advertising, insurance, management, etc.). In general, you get to carry this paper "lost" until you sell the property and reconcile all of the income and expenses while you held the property and estimate any tax liability.
The expenses show on Schedule E are not necessarily the expenses you would incur, you would need to complete your analysis using your own tools (BP has several calculators that can help). In the end, if you are purchasing the condo to get some cashflow you want the rental income to be greater then all of your expenses in order to have a viable deal. Otherwise, you will have to come out of pocket every month to cover the difference. Example,
Income = Rent = 1,000
Expenses = HOA = 330
Mortage = Assume 20% down payment at 5% = $429
Taxes = Assume $100/month
Insurance = Assume $100/month
Property Management = 8% of rent = $80
Repairs Assume 10% = $100/month
Capital Expenditures = 5% = $50/month
Cash Flow = Income - Expenses
Cash Flow = 1,000-(330+429+100+100+80+100+50)= (189) in this case, you have to come out approximately $200/month to cover the property.
Good luck,
