Interesting article from Oz, the bank of mum and dad which is having simialr problems, and 60 percent of first home buyers using the mum and dad bank to borrow to buy a house. Mum and Dad bank is now the 9th biggest lender in Oz! NZ has similar problems, but Oz don't have the same speculation with investors that NZ has had, so haven't had to introduce the same new laws around interest expenses and tax.
Australia has had exactly the same problem as NZ with speculation.
