You are right to ask that question. Generally, real estate is considered a low liquidity asset. I wonder how much their real estate assets are discounted during buy-side analysis.
As it seems like virtually all buying in this market comes from developers and investors hoping to sell at a higher price later, they'll probably be lucky to get a fraction of that.
From Wiki (https://en.wikipedia.org/wiki/Evergrande_Group), I looked at the source for total assets: https://finance.yahoo.com/quote/3333.HK/balance-sheet?p=3333...
At end of 2020: Total assets: 2.3T CNY -> 359B USD (@ 6.40 CNY/USD) Total debt : 0.7T CNY -> 109B USD (@ 6.40 CNY/USD)
