The developer is a company, and the boss has run away, which does not necessarily mean that the company is bankrupt or closed down. If the company is still there and not bankrupt, then your house purchase contract will continue to be performed and will not be affected.
Of course, according to general experience, the boss runs away, mostly because the company has problems, which can be divided into several situations:
First, the director was saved by the government, or the unfinished building was acquired by other directors, then the contract can still be fulfilled, and you still got the house according to the contract;
Second, if the government doesn't save it and there is no real estate agent to buy it, then the real estate agent will enter the bankruptcy liquidation procedure, and the property under construction or the house that has been built but has not been transferred will be auctioned as bankruptcy property (that is, it will be sealed up by the court as you said) to pay off debts. At present, the law has no special protection for buyers, and they can only participate in bankruptcy proceedings as ordinary creditors.
