My wife and I are married out of COP (ANC with accrual). My wife owns an unbonded property that she lets. This means she has a lease agreement with the tenants, although they pay their rent into my account. I own the property that we reside in, which is bonded. The nett effect is that we receive rental income and pay bond interest, albeit on different properties. I would like to be able to claim the bond interest from my wife's taxable income. In order to do so, I assume we need to take out a bond on the rented property. Does it matter (a) in whose name the bond is, (b) from whose bank account the bond repayment is made, and (c) into whose account the rent is paid into?
