Legal analysis: What you actually paid is the down payment plus the loan, which is the total house payment. Because you have paid the total house price before the agreed delivery time, and the premise of general delivery is to pay the full amount before delivery. There is no doubt about it. There is an agreement in your contract about the developer's expected delivery. Either you return a house and the developer compensates for the loss, or you continue to want a house and the developer pays you liquidated damages as agreed.
