I would keep an open mind about buying on the Med coast or the Atlantic coast they both are good. prices have gone up quite a bit in Saidia so you might be a bit late buying there. With the areas around Tangier you can get in at the beginning and get better growth.

For example Moroccan agents based in London Property Borders are selling the Tanjah Golf & Beach Resort it offers 10% rental guarantees for the first 5 years
and the best thing you only need a 12% deposit for a 5 star resort.

Property Borders currently have over 18 developments for sale all over Morocco. Good luck with you search.
