Your income is not relevant. Two pieces of information are:
1. How much cash do you have for the purchase?
2. How much of your income do you want to spend per month on the loan?
Yes. this is more relevant.
I am frustrated from not being able to buy a place because don't qualify for HDB but don't have enough for deposit for condo. Annual pay would more than cover interest payments on a 750k condo, but due to a number of reasons, I dont have anything near the deposit.
