monthly compounding question

Frankling recently purchased a home for 300.000 on which he made a down payment of 100.000. He obtained a 30 year mortgage to finance the balance on which he pays a fixed annual rate og 6%. If he makes regular fixed monthly payments, what loan balance will remain just after the 48th payment???
