What to do with commercial land/rezoning questions.
My fiancee (24f) and I (25f) have a unique opportunity in which my parents are willing to sell us part of their land (a couple acres) for a dollar. This small plot of land actually has its own access to a street running behind my parents property where we could put our own driveway to it. The access is a small strip of land that extends out to the street between two private properties. 
Here's the catch. Many years ago when my family bought the property, it was classified as residential but sometime in the 80s was rezoned as commercial. My mother's attempts to have it rezoned have been unsuccessful (possibly due to her temper). So we would be acquiring this land as a commercial property which we would not be able to build a home on. My questions are this:

How difficult is it to get your property rezoned from commercial to residential in Massachusetts?

How do we go about this process?

If it stays commercial, is it still worth taking her up on her offer and what could we do with the land?

Multi family units are considered commercial and it\u2019s a good hybrid.\n\nI\u2019m in FL, but for re-zoning a plat you\u2019d talk to the city planner (or county if outside the city). Process is pretty simple but lengthy usually, they\u2019ll petition neighbors, etc.\n\nAlso always worth buying land for a couple dollars. Worst comes to worse you\u2019d need to hire a RE attorney to fight to get the zoning changed, but you are immediately making $$. Just be prepared for property taxes.", "replies": [], "depth": 1}]
