I've found an interesting website with all sorts of property and tax info for most countries of the world. The below link is for Uruguay which it describes as having a pro-landlord rental market (same score as UK).
Taking all things into consideration it gives it 4 out of 5 for property investment for non-residents (UK gets 3/5)
Global Property Guide - Latin America - Uruguay: Taxes and Costs

is anyone going to join me here???
