Typically, housing loan companies and institutions analyse your income, age, number of dependents, monthly outgoings, etc. to determine your repayment capacity and hence the quantum of loan to be sanctioned. It is therefore important to present a very clear picture. Normally a property purchased becomes the security for the loan sanctioned and is mortgaged to the lending institution. In some cases to assist you in taking a larger quantum of loan, the lending institution may insist on additional security and / or guarantors. Normally if you have given all the papers an institution does not take more than 5 to 10 days to process your application and sanction your loan. Most institutions are willing to consider joint incomes of applications in the case of joint application for deciding the loan amounts. Some institutions do not charge a co-application for paying co-owners of the property being purchased. Click Here to view the documents.
