A week's stay in the most expensive of these mansions is enough to buy a decent-sized apartment in Johannesburg's northern suburbs - only these rentals are paid for upfront, in cash, and not through a 20-year bond that chains you to your bank.
Nine of these 10 Airbnb listings are - perhaps not surprisingly - in the Cape Town area, no doubt aimed at well-heeled international tourists spending dollars, euros or yen.
A note: rental pricing can fluctuate depending on the season, with the Christmas period usually attracting between 30% and 50% more than off-peak rates. In this analysis, rates given are not based on any particular time of the year, but rather based on an assumed average listing price.
