Suppose you wnat to purchase a house for 650,000. much of the loan would be left after 10 years if the interest rate was 3.8 % and it was a thirty year mortgage? And if you made the montly payments for ten years, and then increase your payment to 4000 per year, how many years would it take you to pay off your loan?

Nevermind, do not answer this question, I figured it out myself.
