When you live in your rental property, every bank transaction is a puzzle: Is this for me or the rental? RoomROI automatically separates your personal spending from rental expenses and calculates exactly what you can deduct.
Traditional bookkeeping software assumes you're a landlord living somewhere else. But when you live in your duplex, house, or multi-unit property, everything's mixed together—your groceries and your rental repairs, your Netflix and your rental utilities, your personal mortgage payment and your deductible portion. RoomROI was built specifically for this: automatically splitting shared expenses based on how much space you rent out, while filtering out purely personal spending.
RoomROI imports every transaction and intelligently categorizes them:
Personal only (your shopping, dining, entertainment) → Automatically excluded
Rental only (tenant-specific repairs, rental advertising) → 100% deductible
Shared (mortgage, utilities, insurance) → Split based on your rental percentage. No separate business account required.
Set your rental percentage once (e.g., "I rent out 2 of 4 bedrooms" = 50% rental), and RoomROI handles the math for every shared expense:
Example:Your internet bill: $80
Your rental percentage: 50%
Deductible amount: $40
✓Works for mortgage payments, property tax, insurance, utilities, HOA fees, and more.
