You can fully own your own home. You need to buy land and develop (buy a house, furniture, etc and sitck on it) it and it will be yours permanently.
Have a look around. Some land develops in here have paid out over $50,000 REAL Money in actual commissions. That's just one company. And they are still growing. Bonus here. You can own multiple homes very easily.
Learn to make money in here if that's what you're after.
Like I said. DO YOUR HOMEWORK. Linden Labs does not get involved in people's business unless it's their fault. You need to check your figures better.
You are just plain wrong. Linden Labs do not cover inworld business disputes ... unless it's their fault... Getting the message?
