excellent friend, it is good to plan for everything and even more in terms of finances and our home, I can give you tips that will help you if you want to now a few more coins, based on your plan I can tell you to make a list of the things that are of real necessity in a house, like for example in the food that is what more is spent here in venezuela, begin by making a menu of meals, from Monday to Sunday, where they place balanced food, but that is more economical to you, limit to eat in the street since that's where the most money is spent, to vary the weekends use homemade hamburgers, all according to what is less expensive, and as for the vehicle if they can use one, and get rid of the other, not sell it unless they need the money from the vehicle for other things, but they can stop using it for 3 months so they can save on gas, and schedule some domestic purchases during those three months before so they do not have the need to spend money in those days, if you can friends, here in Venezuela we have 5 years in a difficult economic situation, and we have learned to survive with what little we earn, success and many blessings.
