Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
Your bank will issue the same 1098 for an investment property loan as they do for your primary residence loan. If your loan is for the purchase of an investment property, you can deduct your interest on Schedule E. If the second property is a second home, you can add that interest on to your Schedule A itemized deductions
Based on your question, I think the Schedule E treatment is most appropriate. It's still deductible, and the end result will be the same.
