Allahabad bank residential property sale-E Auction

Dear Sir, Iam a small private employee in an organisation with 20,000 monthly salary, I had come across a sale notice in one of the online portals, and I have participated in the e-auction,got the property i.e., Residential Flat in e-auction as I am the highest bidder. 25% amount paid as per the sale notice, for remaining 75%, I am taking the loan from the same bank i.e., Loan is in process (With prior intimation to the Authorized officer that I needed loan for balance 75% amount). Now, the bank is going to provide me sale certificate and later registration. But the owners of the flat are residing in the flat, they have not vacated till date, I have approached Bank Officials and asked them that before registration, I need the flat to be vacant and handover to me, even I asked them to issue a notice to present owners to vacate the property, but bank officials are stating that, that is not their responsibility and simply saying the sale notice-PROPERTY is under "AS IS WHERE IS BASIS, AS IS WHAT IS BASIS" 1)In this matter What should I supposed to do, is it my headache to take the property by vacating the present owners? One of the Bank official said that after registration, asked to me to give police complaint. 2) In case if the present owners do not vacate if I insist them also?What should I do? 3)In this regard, bank will not interfere or definitely if I complete the registration process, bank people will wash their hands... 4)Is there any possibility that can I pressurize Bank Officials to let the present owners to be vacated? Please suggest/help me how to proceed, in this regard I am in so much tension and financially I can not go with the complaints/Police cases/DRT Cases etc. Kindly suggest me sir. Thank you. Your suggestions are more valuable. Sridhar
