Looking back at the last year, Kwan said that, ironically, Covid was the best thing to happen to real estate.
"It's brought everyone back to the reality that property is probably the most secure and best investment in the world."
Kwan said that Listing Jozi revealed how Johannesburg has the most underpriced real estate in the world.
