Finally, I do not think the Mortgage One plan is so suitable for businessmen, as it is unlike an overdraft where you can withdraw up to your original principle. In Mortgage One, every month, the portion that is paying towards your principle is "frozen" and is not accessible anymore. This is how the bank reduces its risk. Therefore, towards the end of the loan tenure, you can only withdraw a small portion of the loan. For businesses that require more flexibility, other loans might be more suitable.
