There may be times when you rent rooms in your home to people who are not members of the same family and may not know each other. Under the rental bond system, landlords who wish to claim money from their tenants` sureties must now prove that damage has been caused. This means that each lease should now be accompanied by a real estate inventory. Thus, if you are a lessor and you do not have an accurate rental inventory for your property, you will find it difficult to justify legitimate deductions from a tenant`s deposit at the end of the rental period. Renting a room in your home can be a good way to generate additional income and cover the mortgage. .
