5% and a regard to 30 years. You're not actually paying just 4. 5% of $200,000 as interest; you're paying interest on what stays of the balance after each payment each month. Due to the fact that your month-to-month payment is just a small fraction of the total amount you owe, only a tiny part of the loan balance earns money off, and interest gets charged again on that balance the next month.Your home mortgage payment is the exact same monthly unless your rates of interest changes, however the parts of your home loan payment that goes towards your principal and interest charges changes the longer you have the home mortgage. Interest payments are front-loaded early on and are gradually reduced until primary payments begin to surpass them.
