As an engineer, the ideal loan amount to apply for will depend on various factors, including your income, expenses, and creditworthiness. It is essential to consider the total cost of the property you want to purchase, including down payment, closing costs, and other associated fees. You should also consider your current financial obligations and how a home loan payment will fit into your budget. It is generally recommended that you do not take a loan that exceeds 30% of your gross monthly income. Additionally, you may want to consider the interest rates, loan tenure, and other terms and conditions offered by different lenders before deciding on the ideal loan amount to apply for. Ultimately, it is essential to carefully evaluate your financial situation and choose a loan amount that you can comfortably afford to repay.
