1. What is the Duplex Mortgage Calculator?

The Duplex Mortgage Calculator helps estimate monthly mortgage payments for duplex properties using a specialized formula that accounts for the unique aspects of duplex financing and the division of payments between two units.

2. How Does the Calculator Work?

The calculator uses the duplex mortgage formula:

\[ Payment = \frac{(Price - Down) \times r (1+r)^n}{((1+r)^n - 1) \times 2} \]

Where:

$ Price $ — Total property price ($)
$ Down $ — Down payment amount ($)
$ r $ — Monthly interest rate (annual rate ÷ 12)
$ n $ — Loan term in months
$ 2 $ — Division factor for duplex properties

Explanation: This formula calculates the monthly mortgage payment for a duplex property, dividing the total payment obligation between the two units.
