There was an automatic transfer on my account and then a $3.00 transfer fee on my account. Why did this occur?

In most cases, this $3.00 transfer fee is from your Overdraft Protection. Overdraft Protection applies to all transactions, excluding OnlineAccess and PhoneAccess transfers, and may help prevent overdrafts by automatically transferring funds to your checking account from another deposit account you may have at Mainstreet for a fee.

Overdraft Protection transfer fees are waived for Classic Club members.

Why was I charged an overdraft fee of $27.50?

Mainstreet Credit Union offers Overdraft Coverage options to help you when life happens. Our Overdraft Privilege charges a fee of $27.50 per item.  Overdraft Privilege allows you to overdraw your account up to a disclosed limit for a fee to pay a transaction. Even if you have Overdraft Protection, Overdraft Privilege is still available as secondary coverage if the other protection source is exhausted.

What is the difference between a fixed-rate loan and an adjustable-rate loan?

With a fixed-rate mortgage, the interest rate stays the same during the life of the loan. With an adjustable-rate mortgage (ARM), the interest changes periodically, typically in relation to an index. While the monthly payments that you make with a fixed-rate mortgage are relatively stable, payments on an ARM will likely change. There are advantages and disadvantages to each type of mortgage. The best way to select a loan product is by talking or meeting with one of our Mortgage Loan Officer.
