No car payment, get a decent used vehicle to get you to point A and B. Don’t rent. Get a small travel trailer, live in that. Second source of income. Buy old cars, equipment etc., resell them. Or, get a second job utilizing a skill like welding, building, handy man, etc. cash money jobs. Don’t buy anything that you don’t need or if it doesn’t make you money. Thrift stores for clothing and shoes, Aldi’ for groceries. Don’t drink, smoke or do drugs. Don’t get a girlfriend or get someone pregnant. I guarantee that if you do this, you’ll be able to get a house by the time you are 27.
