Well to be honest…..not a good offer.. for a 13 yrs experienced person.
are they providing you a transportation allowance or a car? if not 2500 will go for car either hire or monthly installment.living cost will be 4000 to 5000...

You cannot save much..unless your wife also works...which is not a good option as you have a 2yr old kid. Try to negotiate your salary...settle for minimum 15,000/- otherwise it’s not worth
