A housing loan is a loan offered by banks and financial institutions to individuals who want to buy or construct a house or flat, where the property is mortgaged as security until repayment. Top housing loan providers in India include SBI, HDFC, PNB, LIC Housing, ICICI Bank, and Axis Bank. It is important to research loan options, check your repayment capability, read agreements carefully, take insurance, and ask about additional charges to fully understand the home loan process.
