we entered an agreement to sell a property in M.p.,and the byer agreed to pay within 3 months fully.Now he wants bank loan on this property .Now he is insisting on more papers like NOC to sell ,allotment letter .V have already gave most of these documents.But due to some mistakes done by Authority in original lease paper and allotment letter,though v coopertated with him getting corrected .but correction needs some time,taking benefit of this situation ,he wants the payment time should start from the date of all the correction be made by authority.Bank is accepting his case.So my question is that nowhere in agreement said that seller will not for his bank finanace.it his headache to get loan,taking advantage why he should get more time beyond three months.pl.clarify this .
