For my next IP purchase I want to borrow 100% of the purchase property prices ie 80% from the new IP and 20% through equity release of existing IP.. However the bank is not doing any equity release on current IP, so I will have to change banks if I want access to this equity.. My thoughts are I won't bother going through the refinancing process till I find the right IP, however refinancing will take a while and I would need longer than the cooling off period to organise this. My broker suggested the following and she seems to think that it won't effect my tax deductibility but I'm not sure.. She suggested, putting forward my own money after the cooling off period and then when the property settles taking back the excess funds. I don't know about this, would this contaminate my loan ? Ie not then 100% tax deductible.. Keen to get your thoughts !
