MA Regs say yes... You must be licensed in MA to hold a public auction on a home in MA. However you don't need one for online auctioning such as Ebay...
For more info you can always give me a call and I'll be happy to help you locate the information you are needing or you may contact the MA Division of Standards at 617-727-3480 ext. 21134
Hope this info help you. Please feel free to contact me with any questions you may have.
:-) Cindy Nina-Soto
