This is a hypothetical situation but I would like some insight in to how possible this is. My understanding is that normally you have to be 18 to sign a legal contract as sole purchaser (happy to be corrected / informed of exceptions). Max turns 18 has saved a deposit since he was 8 - birthday money, pocket money, part-time work and wants to buy a house. Finds a suitable house where he can manufacture equity and wants to buy it. How difficult is it for Max to get a loan - assume he has only just finished year 12. Even if he has parents willing to co borrow or act as guarantors - would they loan to him? (Assume current lending conditions).
