Applications

Example Commercial Mortgage Application

For example, let's say you want to purchase a commercial building for $1 million with a 20% down payment. Based on current market rates, the monthly mortgage payment would be approximately $5,300 over a 30-year term. This translates to an annual interest rate of 4.5% and a total cost of $1.2 million over the life of the loan. However, please note that commercial mortgages often have different interest rates and terms than residential mortgages, so it's important to consult with a commercial mortgage lender for the most accurate estimate.

Property Taxes

Our mortgage calculator accounts for property taxes by assuming an average annual property tax rate of 1.2%. If your actual property tax rate is different, please enter the appropriate amount in the 'Additional Payments' field.

Other Applications

The mortgage calculator can be used for other applications beyond buying or refinancing a home, such as calculating the monthly payments and total interest for a commercial property or rental property. Additionally, the calculator can be used to estimate the impact of prepayment penalties on a loan.

Loan Assumptions

The mortgage calculator allows you to assume loan terms that may not be available from all lenders. For example, you can input a longer or shorter loan term, or assume a different interest rate. This can help you estimate the potential costs and benefits of various loan options.
