1. With cibil less than 750 you may not get best deals
2. 60L loan on 70K salary…only bank will be able to tell you how much are are eligible for looking at your expense/inhand salary and other stuffs…. personally amount is bit over stretched. . Your EMI alone will be around 45K per months consider 25 years and 7.5% interest… (Interest is expected to move up only).. you won’t get it for less than 7.5 considering your score ..best this days is 7% post recent hike
3. Do consider SBI for home loan.BoB is also good..No idea about IOB .won’t go for HDFC or ICICI. You can get home loan from anybank as long you are able to provide them required set of documents
