There are at least three stages. A sales contract by installment refers to a sales contract in which the buyer pays the full price of the subject matter in batches after receiving it, or the buyer pays a certain amount of money in batches before the seller starts to supply it in batches, but the balance after the buyer receives all the goods should be paid in at least two installments.

The advantages of installment payment are as follows:

1, less investment. You can realize your dream of buying a house without spending a lot of money and paying a certain down payment. Just-needed buyers don't need to find a house to rent, and they move frequently. The monthly payment may not be much different from the original rent, but you have your own house. If you spend less, you can make a profit.

2, the funds live. Loan buyers can separate funds, such as buying a house for rent, leasing and supporting loans, and then invest in other projects, so the use of funds is more flexible.

3. The risk is small. Mortgage loan is to borrow money from the bank to buy a house. In addition to buyers concerned about the quality of the house, the bank will also review it. In this way, the insurance for buying a house will increase.
