• Bullet Repayment : The principal will be repaid in full at maturity and only interest will be paid before then.
• Equal Principal Payment : Repay the principal at the same rate every month. Interest is paid as much as the remaining balance, so the principal is reduced as much as the principal is repaid. That is, the payment amount decreases over time.
• Equal Amortization : The total interest and principal are divided by the period and the same amount is paid equally every month.

New DTI is a way of incorporating all mortgage principal and interest into the screening. It is a more relaxed indicator than a DTI that reflects the principal and interest of all loans, but if you have existing mortgage loans, it is an indicator for mortgage regulation that makes additional loans difficult.
