Definition: Sure, I would be happy to explain the term "mortgage refinance rates." The mortgage refinancing rate refers to the interest rate on a loan that you are currently taking out (the original mortgage) and paying off with a new mortgage loan. The rate is typically based on factors such as the type of loan you have, your credit score, and the down payment required for the refinance. The refinance rate can change every time you make a refinancing request, so it's important to understand how it will affect your current loan terms. It's also worth noting that mortgage rates can go up or down over time as interest rates are adjusted by lenders based on economic conditions and other factors. To calculate the new refinance rate, you'll need to know your original loan amount, the new interest rate you're trying to get, and any fees associated with refinancing. You may also want to consider whether the refinance is a "prime" or "sub-prime" mortgage, which can affect how much you have to pay for the refinance.
