non resident, cant borrow that much lah
LZ need to be more realistic. aiming at 30% deposit is more reasonable.
Income is good, 250k deposit, base on 30% deposit, buy price should be around 830k. Your income should be able to serve a loan of 580k without any problem.
Overall, major weakness is your non resident status, but both servicing (income) and deposit (LVR) are sound, should be ok as long as both contracts are permanent. vanilla deal any banker/ broker should be able to get this one for you.
