Massachusetts Condominium by-laws

[Amy Fortes]

Hello, 

I am a landlord of a condo in Massachusetts and am considering selling while my tenants are still in a lease term with me. I think there may be some condo rules/by-laws that prohibit this (that when a unit is purchased it needs to be owner occupied first and a for a certain amount of time before renting). Not sure that they'd even truly enforce this if it was the case.  Do you have any experience that this could be true? Who is the professional I would ask about this to clarify? 

Thanks!
