AI summary

To estimate your mortgage borrowing power, a rough guide is five times your gross salary. For a more accurate figure, use an online calculator or get pre-approval, though the final amount depends on the property.

Lenders assess your income, expenses, and credit rating. A 20% deposit is standard for securing the best rates and avoiding fees. A mortgage broker can help navigate different lender policies to find the best fit for your specific financial circumstances.
