Thank you Simon & mum.
Simon,
Both properties are joint tenants.
If I refinance the T/H and take the money out and put it in a offest against the new PPOR does that makes the new interest on T/H tax deducitble or not ?
BTW my wife does not works and has no income. Her part of the -ve gearing gets wasted (accumulated) anyway !!! However will save CGT later.
