What is the cheapest area in Hong Kong?

I'm curious, when it comes to real estate prices in Hong Kong, which area stands out as the most affordable? Is there a particular district that offers a more cost-effective option for those looking to purchase or rent property in this bustling metropolis? It would be intriguing to know if there's a neighborhood that manages to buck the trend of sky-high prices, offering residents a more wallet-friendly living experience amidst the city's vibrant energy.
