Actually, you might benefit by claiming this income as rental income report this on Schedule E. This is because not only can you deduct the property taxes and mortgage interest (as you currently do on your tax return on Schedule A as a 2nd home) but as a rental property you can depreciate your home, deduct repairs and maintence, deduct utilities that you should pay for your father, electricity, gas, garbage, and any incidental expenses associated with this property.
Of course, if your AGI exceeds $150,000, then passive losses are not deductible. At this point, you should talk to your CPA or tax advisor to determine which position to take based on your unique circumstances. |
