I have opted for loan from SBI and my loan processing is at final stage (could be disbursed within days). SBI has granted me a loan of Rs. 19 Lakhs and i communicated the same to lodha. The builder is now demanding the 20% of the gross value of the flat, i.e., 30,58,000/-. So far i have paid them Rs. 8,71,000/-. They are still demanding the remaining amount Rs. 2,85,000/-. Even they have charged interest for the same. Whereas, they are yet to provide the complete set of documents required for finalisation of loan from bank. Is it fair
