Taking a loan from the bank to purchase a house

Q: I am from India. We are three bothers and we have only one home. With the grace of Allah (Ta'ala) coming year I will get married. So, I was thinking of buying a home. As I don't have enough money. I need to take a loan. But here in India we don't have Islamic banking. And I don't have other means to get that required amount. What is best for me?

Avoiding interest when paying off a loan

Q: I would like to perform hajj in the near future so I need to pay off two loans. I have student loans from over a decade ago that I would like to pay off in full. However, I don’t want to pay the interest that has accumulated on these loans. If I can settle to pay just the amount of the original loan, will that be permissible? Also, I have an outstanding loan from a certain company. If the company agrees to let me pay just a percentage to have the entire loan forgiven, is that permissible?
