Your Arizona LLC can buy property in Las Vegas. I currently work with an investor in North Las Vegas that buys properties from an out of state investor. If you would like to work with someone with local knowledge and a good reputation I would love to help you out. I know of several properties around my area that would make for great investments but we would have to discuss your companies needs and expectations on the transaction. Shoot me an email at email@example.com if you would like to talk more about it.
