In real estate finance, P.I. stands for principal and interest, referring to the two primary components of a loan payment. The principal portion reduces the outstanding loan balance, while the interest portion represents the cost of borrowing the funds.
The term P.I. is commonly used to describe what is included in a monthly mortgage payment, excluding other possible charges such as taxes and insurance. Understanding the principal and interest breakdown helps borrowers evaluate loan amortization and payment obligations over time.
