Having lived in both and homesteading, including livestock, I can say there are pros and cons to both. Maine overall has lower property taxes, but Vermont will abate property taxes for your primary residence based on income. Vermont has a larger, more established farm to table scene if you are looking for side income. Very northern VT is much less regulated than almost anywhere in the country; however, some of the laws have been shifting in VT rapidly in ways that native Vermonters likely would not have chosen. There are many places in Maine where you can't build a second house on your land, so it is worth speaking with the Code Officer before buying a parcel. Overall, I have found the cost of living is lower in Maine, but I miss the inexpensive and amazing local food in VT. Happy to chat more about this if you want to DM me.
