This is along with other major cities, such as Berlin, London, Singapore and Shangai, says Andrew Golding, chief executive of the Pam Golding Property Group, which is in association with Savills.
This year, capital values across the 27 cities in the index are forecast to grow by 1.8% on average.
However Lisbon, Sydney and Moscow are projected to have growth greater than 6%.
Golding says: “Clearly evident is that Cape Town offers international property investors exceptional value for money, with residential property to be had at €3000 (about R48166)/m² , compared with between €9000 and €24300 in New York, and above in other leading global cities.”
