There's no single fixed maximum that applies to every applicant, since the ceiling is generally driven by a multiple of your monthly salary, commonly in a range set by each bank's own policy, combined with the overall debt-burden ratio cap once your existing obligations are factored in. A higher salary and a clean credit history generally support a larger approved amount, but the practical maximum for any individual applicant is ultimately whichever is lower: the bank's salary-multiple cap or the amount that keeps your total monthly obligations within the debt-burden ratio limit.
