So I'm considering moving into one of my investment properties and subletting the second bedroom, which has posed a few questions: 1. How do you work out how much of a percentage you can claim on deductions like interest, repairs, bills, renovations, etc. Is it a simple case of 2 people, 50-50? Or does it depend on value/rent? 2. If I sublet the property fully furnished, will I be able to claim deductions on the furniture/appliances/fixtures they have access to? So things hopefully can make more sense, here's a similar hypothetical scenario: - Bob has a 2 bedroom investment property worth about $300,000 - Up until recently, the property was rented out for $300 a week - The tenants vacate - Bob renovates the property, putting in new tiles, paint, kitchen, bathroom, etc - Bob fully-furnishes the property with things like beds, cupboards, dressers, tables, chairs, sofa, television and all appliances like kettle, toaster, oven, etc Bob then moves into the property, taking up one bedroom and then rents the second bedroom out to a subtenant for $150 a week. This covers both the tenants rent and share of the bills and they are literally allowed to use and access everything throughout the property, except for the main bedroom.
