Which is more cost-effective to buy a new house or a second-hand house?

To buy a new house or a second-hand house, we must first understand the advantages and disadvantages of both. New houses have advantages over second-hand houses in down payment, taxes, property rights, apartment type and property. Second-hand houses have advantages over new houses in supporting facilities, lots and price elasticity. New houses and second-hand houses have different advantages. Property buyers must first determine their own purchase method, whether it is full payment or loan. If it is a loan, how much can the down payment be? After making a clear budget, you should make a reasonable decision based on your purchase purpose, preferences and the prices of new and second-hand houses.
