Create a consistent monthly view
Track available nights, booked nights, average nightly rate, gross rental revenue and operating costs separately. Record installation dates and periods when the property was unavailable. Compare similar seasons and note pricing changes, renovations and other factors that may explain results. Share the period and assumptions whenever you publish a success story.
Keep the supporting documents
Organize invoices, receipts, booking statements and service records by property and date. For a property you also use personally, maintain a record of rental and personal-use days. In the United States, rental income is generally reportable; expenses and vacation-home use are subject to specific tax rules.
Get advice for your situation
Whether a cost is currently deductible, must be depreciated or is limited depends on the facts and applicable rules. Ask a qualified tax professional to review your situation rather than treating a product purchase or a calculator result as a tax deduction.
