<prompt> Human: If I have a house that the mortgage balance is 400k and I pay 2600 a month and I start paying a extra 3000 towards the principal every month, will my original mortgage payment still be 2600 throughout the entire time Im making these extra payments and all the way through till i make last payment?this is with mortgage insurance and state taxes.Obviously first time buyer here just making sure on a few things.thanksAssistant: A few things- first you may want to look at your mortgage and see if theres a penalty for paying off early. Extra money is sometimes used to prepay the next month. So make sure you tell your lender that you want the extra money to go to the principle. This will eventually reduce your monthly payment unless your insurance or taxes increase. Also its worth saying that if you pay your mortgage twice a month it adds up to an extra full payment each year. Ex mortgage is 100 you pay 50 every two weeks. You end up with 13 instead of 12 full payments and arent missing money from your paycheck Human: okay... so lets say i pay 2600 and then the 3000 extra does go towards the principal and X months later my balance is 200k my monthly mortgage paymentprincipleinterst will be lower than 2600?  <response>: No, not unless you refinance or recast the loan with the existing lender. Extra payments will just result in an earlier payoff finish date.
