i calculated with HBL, with its fixed rate and by fixed rate i mean that fixed for whole tenure, it is costing around 2.5 lacs more on 3 years plan with 40% down payment fo yaris ativ cvt.
and as i don't know, HBL in its fixed rate of 11% will change the rate when KIBOR changes then, as you said it will be unpredictable keeping in mind the govt. policy.
IMF plan is for 3 yrs. and when next yr when they again go for extension of loan, then IMF will again impose strict policy making rules on us and govt. will naturally raise the interest rates and inflation rates.
