What does it mean to lock the interest rate?
Mortgage rates can change from the day you apply for a loan to the day you close the transaction. If interest rates rise sharply during the application process it can increase the borrower’s mortgage payment unexpectedly. Therefore, a lender can allow the borrower to "lock-in" the loan’s interest rate guaranteeing that rate for a specified time period, often 30-60 days, sometimes for a fee.
Should I lock-in my loan rate?
It's unsure how interest rates will move at any given time, but your lender may estimate where interest rates are headed. If interest rates are expected to be volatile in the near future, considering locking your interest rate may be good because it allows you to qualify for the loan. Or, if your budget could handle a higher loan payment, or lender's lock fees, you may want to let interest rates "float" until the loan closing.
