Absolutely, as long as the property is eligible for subdivision (meaning the spun off lot meets minimum requirements for your location) you have every right to sell. The first step would be taking a copy of your survey to the Building and zoning dept to assess your situation. Once you know it is possible, a local agent like myself can help you establish value for the land. If you need any further assistance, let me know.
I'm sorry I meant to write sell land. Not see. I have over an acre of land at my home and was looking into possibly subdividing and selling part of the lot in the backyard. I know each town is different and have different rules. Thanks for getting back to me!
