It's pretty standard in MA, though often it's more like 3 of 4 for first/last/security/broker fee.

In MA, at least, they technically need to put anything prepaid (security and last month rent) into a savings account and give you the interest. Or a flat 5%/yr if they don't put it in a bank account. I can't say I've really seen the interest but usually it's not enough to bother pushing as long as they give me my full deposit back. Many might not even know they owe this, though some probably just count on tenants not being aware.
