Property market...anyone help?

Have some USD and would like to invest in a property in the US. If anyone could provide me with some advice of where the best locations and yields are in your area it would be gratefully appreciated. Have done a lot of research and there is so much conflicting information that the whole exercise is turning into a nightmare.

Any input to a girl 'downunder' would be gratefully appreciated! Will buy you a drink if I end up in your city buying!!
