<human>: My family is constantly borrowing money from me. I live at home rent free. I'm living at home, so I can pay off my student loans faster. I am getting to the point I would rather live elsewhere and pay rent then deal with them. I'll probably end up saving money.

They are all very irresponsible with money and never pay me back. I have to ask multiple times and they just ignore it. "It's only a $100 relax. That's nothing." Yeah it's $100 this time, but that adds up overtime. What is frustrating is their spending habits. I am trying to pay off my loans and that's why I decided to live at home. They just buy whatever they want and don't plan for the future. They'll spring expenses on me last minute because they don't have money. It's even more annoying because my sister will go to my dad to borrow money b/c she needs a medical procedure. Dad doesn't have the money, so I have to spot her the money. She now owes me the money plus the money she owes me before.

For example, my sister has multiple luxury items like a big tv, newer computer, speakers, etc. She owes me about $150 at this point, but just avoids paying me back. I wouldn't mind letting the $150 go unnoticed, but it's the fact she has all these luxury goods when I don't spend my money on it.

I'm starting a new job where I'll make decent income, but I have a lot of debt to pay off. I don't want it to become the bank of the house because I manage my money better.
How do I approach the situation without looking cheap or greedy?
