Sorry... I explained my self badly.. My parents continued to live in the house and paid rent to the four of us.
None of us (the children) lived in the house after we purchased it from my parents.
We used the rent to pay the mortgage and any upkeep/repairs etc that needed to be done on the house. We have not done any major works on the house since we bought it.. just maintenance and upkeep, servicing of boilers etc.
Do costs of sale mean the conveyancing solicitors costs and the estate agents fees?
