Your result, explained
Based on your income, debts and deposit, lenders would likely approve a home of up to about $239,817, with a $139,817 mortgage costing around $918 a month.
That is the maximum a lender allows, not necessarily what is comfortable. Leave room for savings, repairs and rate rises: many buyers aim 10–20% below the maximum. Paying off a car loan or credit card first is often the fastest way to raise your budget, because every monthly debt payment reduces what you can borrow.

Serviceability buffer
