  • Homeowners Insurance
    If you have recently purchased a new home after owning another for many years, you may need to review your home insurance needs. Our agents at John M Costello Insurance Agency Inc. are here to help you discover new lines of coverage relevant to your needs. John Michael Costello excels in assisting homeowners with every concern. Your homeowners policy is going to be with you as long as you own your home, so make sure it is going to work hard to protect the things that matter most to you.

    Home insurance policies are not one-size-fits-all. In fact, the wide variety of property types and many different features found inside homes require a different approach. In order to give our valued customers more personalized insurance solutions, we have chosen to team up with Nationwide, a leading provider of home policies and other insurance products.

  • Life Insurance
    At John M Costello Insurance Agency Inc., we want to make customers aware of how easy and affordable life insurance is. We know many people in Somerville think they cannot afford to have a good policy that protects their financial interests. That is why we work with Nationwide to provide customers with the diverse coverage options they need to sleep peacefully at night.

    Affordability is a major concern for most. In addition to choosing coverage based on what you can afford, you need to think about how you or your loved ones may need to use your policy proceeds. Maybe you’ll need to replace lost income or pay for long-term care expenses and your kids’ college education. These issues may not completely encompass your current concerns. However, keeping them in mind will help you discern the proper coverage level for your situation.

    There are circumstances where customers find it more beneficial for them to layer several term life insurance policies instead of purchasing whole life insurance to give them long-term financial security.

    By speaking with a life insurance agent who works with Nationwide, you can gain a better understanding of options that are ideal for your situation. The amount of coverage you need can help you meet your current and future financial goals.

    To better understand coverage options, we encourage you to contact John Michael Costello at (617) 666-4779 to arrange a time to meet in office at 311 Highland Ave,Somerville,MA,02144 to discuss your needs. For additional convenience, our agents are ready to help you go over coverage options over the phone.
