The specific compensation methods are: calculating the house price difference, resale interests and the compensation requirements of the observant party. On the whole, the breaching party will compensate the observant party with the compensation amount.

The contract law stipulates that if the agreed liquidated damages are lower than the losses caused, the parties may request the people's court or arbitration institution to increase them; If the agreed liquidated damages are higher than the losses caused, the parties may request the people's court or arbitration institution to reduce them appropriately.
