Tenant security deposits - Massachusetts

[Sarah W Adler]

In Massachusetts, can a landlord commingle multiple investment property security deposits in one account, as long as that account complied with all MA laws (interest bearing, separate from landlord funds, etc)?

I have 5 investment properties and currently each security deposit is held in a separate interest bearing account. I am wondering if it complies with the law to move all 5 deposits into ONE single account, to be used only for tenant security deposits?
