Final answer:
To determine the amount you owe on your mortgage today, calculate the remaining loan balance using an online mortgage calculator. The remaining loan balance in this case is approximately $573,848.
Step-by-step explanation:
To calculate how much you owe on your mortgage today, you need to determine the remaining loan balance. Since the mortgage is exactly four years and eight months old, there are 4 * 12 + 8 = 56 months remaining in the original 30-year term.
Using an online mortgage calculator with the original loan amount, interest rate, and number of remaining months, you can find that the remaining loan balance is $573,848.
Keep in mind that this calculation assumes you've made every payment on time.
So, the amount you owe on the mortgage today is approximately $573,848.
