You have lived in Mexico so the weather here will not bother you much. It is ver humid here all year round.
Your kids will have to attend international school here. There are many available but costly.Apartments -condominium living or rental of houses are expensive too. Depending on location and type of accommodation, prices can range from $4K -$20K.
Transportation is convenient -there is public transportation -train and buses. Owning a car is expensive-the cost of the car + certificate of entitlement (new car $50K-90K).
My husband and I live here rather comfortably because we do not have dependent children and are on good incomes.
