There are several advantages and disadvantages to consider when buying property in the town of Greenland, New Hampshire. Here are a few:

Advantages:
- Location: Greenland is a small town located just south of Portsmouth, NH, which offers access to the amenities of a larger city while still maintaining a suburban/rural feel.
- Quality of Life: Greenland has been frequently recognized as one of the best places to live in New Hampshire due to its low crime rate, excellent schools, and abundance of outdoor recreation opportunities.
- Home Values: The median home value in Greenland is currently around $500,000, which is relatively high for the state of New Hampshire. However, this can also be seen as an advantage for homeowners, as it suggests a strong housing market.

Disadvantages:
- Cost of Living: While the cost of living in Greenland is not as high as some larger cities in the US, it is higher than the average for New Hampshire. This can make it difficult for some residents to afford to live in the town.
- Limited Shopping and Dining Options: While Portsmouth is located nearby, Greenland itself has relatively few shopping and dining options. Residents may need to travel to neighboring towns for certain essentials or restaurant choices.
- Severe Weather: Greenland, like much of New England, is prone to severe winter weather conditions. Snowstorms and blizzards can make travel and daily life difficult during the winter months.

Overall, buying property in Greenland may be a good choice for those who value a high quality of life, outdoor recreation opportunities, and strong home values. However, it may not be a good fit for those looking for a low cost of living or more urban amenities.
