SoupDragon,
Interesting! the more I think about these issues, the more I realise that tax has huge implications which just arent addressed when one purchases the property. Or perhaps I have been naiive. I have considered stability of the econmy and hence currency as part of due diligence, but not in that CGT scenario. And some of the more 'stable' countries USA/Europe have seen high currency changes.

Its generally harder to sell properties abroad, takes more time, more cost so most of my foreign purchases are long term (10yrs+). If the exchange rate has fallen since purchase either you'd have to wait longer to sell, or keep the funds in the local currency and hope for a currency rise.

Rental income and hence local income tax in US and Turkey are my immediate concerns. Then later Morocco and Brazil. Think I need to budget heavily for accountants or give up work so I can spend my time filling in foreign tax returns!
