Is it possible to open a personal line of credit without house

[Naeem Barbour]

I have pretty good credit probably sitting at a high 700's now. The only thing is that I lack a strong established history in credit. My accounts aren't old enough t get approved for higher limits such as 25k and up. I was going use a credit booster and then apply for a personal line of credit. How would I be able to get that line without a home or a business? The reason I would use the personal line of credit is to be able to open up the option for cash buys.
