The down payment required for a home loan is typically determined by the lender and the property cost. In India, lenders typically finance up to 75-90% of the property cost, with the borrower responsible for the remainder as a down payment. As a result, if the property costs Rs. 50 lakhs and the lender offers an 80% loan, the borrower must make a down payment of Rs. 10 lakhs. However, a larger down payment is recommended because it reduces the loan amount and EMI burden.
