Okay, let's go through this step-by-step:
1. 80% LTV on $750,000 house = $600,000 total loan amount
2. 30-year mortgage at 4.94% average rate.
$600,000 loan amount / 360 monthly payments = $1,666.67 monthly payment
3. Interest on first payment (November 15, 2018):
$1,666.67 payment
x 4.94% annual rate / 12 months = $151.67 interest
4. Principal paid on first payment: $1,666.67 - $151.67 interest = $1,515 principal
5. Interest on second payment (December 15, 2018):
$1,666.67 payment
x 4.94% annual rate / 12 months = $151.67 interest
6. Principal paid on second payment: $1,666.67 - $151.67 interest = $1,515 principal
