1. For SIIB, I guess the ROI for 10 Lacs is 12.5% , and for Full Moratorium it's 13% You can contact Mr. Amol Vairagar at 9822526363 from Credila Financial Services for accurate information. He will help you to get through the loan process.
2. Yes, it is possible no matter where you are taking admission. Loan is given to you so that will not matter even if you are changing College.
3. These days Credila & SBI are offering best Rate of Interest but SBI is slow in their Loan Sanction process where as Credila (Private HDFC Ltd Co.) has faster process.
All the best!!
