Key Features of Banks
To further evaluate banks and determine which one is right for you, consider the following factors.
Type of Institution
Research the type of institution you desire. Traditional banks offer a wide range of products and services, but sometimes charge higher fees. However, their interest rates are lower. Completely online banks have no physical branches but often have lower fees overall.
Maine has a significant number of credit unions. Credit unions are member-owned or community-focused, and they occasionally offer nationwide banking through shared networks.
Location and Hours
Select a bank with locations throughout Maine. If you prefer to do banking in person, find one with a building near you. Note which holidays the bank closes for and its weekly hours. Check if the bank has ATMs available nearby for easy, in-person banking. If you want a bank with 24/7 accessibility, institutions with an online application work best.
Reputation
Is your bank of choice small and local or expansive and nationwide? This could determine the amount of personalized care you will receive. Check the bank’s financials to determine its stability, and read customer reviews. For your security, the bank should be FDIC-insured or NCUA-insured.
Account Perks and Fees
Many banks offer perks when customers open accounts with them. See if any bonuses or rewards are available before you sign up. Some accounts have limitations, so ensure the account meets all of your personal needs.
Fees may apply, so look for plans with low or no monthly maintenance fees. Also, check the charges for overdrafts and wire transfers. The Annual Percentage Yield (APY) is important when comparing the bank’s savings account offerings. Decide whether you want simple checking or complex services, as that influences perks and fees as well.
