Anyone from Delaware? Wondering about the cost of living there

Hi everyone, I’m thinking about moving back to the East coast as my company might start a new branch there.

Anyone have any idea about living in Delaware? I’ve been there once a while ago, isn’t it a tax free state? They have a really nice ice cream store lolllll loved their green tea peach flavor.

Also might go to Goldey-Beacom College to continue my employment. How is their MS management? What’s the difference between that one and the MBA program?

Thanks in advance for reading!
