Condo Purchase - Tax Strategies [US]
If it's a rental, you will write off the losses via Schedule E. You should read this document and its instructions to understand this fully. You will also take depreciation on the value of the building, not the land, over 27.5 years. If you don't understand this, search here, there are discussions that cover this.  If it's not a rental, but your home or second home, you take the interest and real estate tax off you tax via Schedule A, if you itemize. (I see the tag 'rental' but leave this line for sake of a complete answer.)
