Real estate developers provide buyers with various payment options. These schemes are called as subvention schemes.

There are various forms of subvention schemes. Some of them state the part amount of the total payment that the buyer has to make at the time of booking and the rest after the offer of possession. This particular scheme is known as interest rate subvention scheme.

While other subvention schemes are given out in a ratio of A-B-C where A is the total amount to be paid by the buyer; B is the amount paid by the bank to the builder at various stages of construction; and C is the amount paid by the bank to the builder on offer of possession to the customer.
