define principal in home mortgage. define interest in home mortgage.?

Question

out of principal and interests which is considered the house note

Answer 1

I'm not sure what you mean.
If you borrow $100,000, THAT is the principal.
You will repay something like $150,000-----the extra being the interest.
If you can pay MORE than required each month, that comes off the original $100,000, leaving less PRINCIPAL that you'll have to pay INTEREST on.

Answer 2

Principal is the amount owed. Interest is what is paid on the use of the money.

The house note is the total payment for the period, part of which is interest, and part usually is principal. Many home notes also include an amount for a reserve to pay taxes and insurance.

The payments are usually "amortized" which means you pay the same amount every month, but each successive month you pay more principal and less interest, so it goes down to a zero balance in time, with equal payments.
