Some other banks will tell you 40% to manage your expectations but if you have a good credit and a the deal makes sense, the down payment shouldn't be above 30%.As to the managing of properties, if you can self-manage out-of-state in the US, there are no reasons as to why you couldn't do it internationally too and some investors do.
