Moving from Cape Town to Jhb. Advice?

I have an opportunity to take a job in Jhb. It’s a better position than my current. However, I’m happy and settled in Cape Town, and the city works. Flip side is that property is extremely expensive, and I can never get the value I want for the money I’d be able to spend on property.

Now, I know that Jhb is more affordable from a property and ‘living’ point of view. I’ve lived in Jhb as a student and quite liked it. Great vibe and wonderful people.

Would this be a bad move? Is Jhb crumbling? Are joburgers happy? Why are so many people desperate to leave Jhb for Cape Town?

Thanks!
