How to forecast loan prepayment



Hello Everyone,

I have a dataset which contain historical payment detail of loan by customer’s (with many variables like country, loan type, loan status, etc) and need to predict amount paid by customer for next 6 months. I new to analytic world and find it difficult to figure out any approach to start with. I did a liner regression over it by ignoring loan id’s but that doesn’t look logically correct since then I am considering individual behavior.

Can someone point me in a right direction, is there any book or tutorials on such kind of problems where I can find relevant answer?
