However I think that a non US citizen will find it extremely hard to get a mortgage in the US. If you check out Rich Dad's site, he's got some video clips and they state where they are buying right now in the US and why.
Why not do some due dilligence on the link you sent? Contact estate agents/ letting agents in that area to confirm if it's sounds genuine.
