1. What Is Duplex Mortgage Calculator Based On?

The Duplex Mortgage Calculator estimates monthly mortgage payments for duplex properties based on income, property price, down payment percentage, interest rate, and loan term. It helps potential buyers determine affordability and plan their investment.

2. How Does The Calculator Work?

The calculator uses the standard mortgage formula:

\[ Payment = \frac{LoanAmount \times MonthlyInterestRate \times (1 + MonthlyInterestRate)^{NumberOfPayments}}{(1 + MonthlyInterestRate)^{NumberOfPayments} - 1} \]

Where:

\( LoanAmount \) — Property price minus down payment
\( MonthlyInterestRate \) — Annual interest rate divided by 12
\( NumberOfPayments \) — Loan term in years multiplied by 12

Explanation: The formula calculates the fixed monthly payment required to fully amortize a loan over the specified term.

3. Importance Of Mortgage Calculation

Details: Accurate mortgage calculation is essential for financial planning, determining housing affordability, comparing loan options, and making informed real estate investment decisions.

4. Using The Calculator

Tips: Enter your annual income, duplex price, down payment percentage, interest rate, and loan term. Ensure all values are positive and within reasonable ranges for accurate results.
