This is another type of loan against property (LAP) in which the drawing power (DP) keeps reducing in proportion to principal payment of the limit. At the end of loan tenure, the DP becomes zero. It allows you to deposit or withdraw funds as per your convenience and you need to pay interest only for the funds utilized. Thus it has the flexibility of normal banking account. Like a normal LAP, DOD is financed against property and the DP is based on the value of property financed. DOD is of two types – fixed principal repayment and variable principal repayment.
