[Landlord-US-MA] My tenant is disabled and won’t pay

Hi, I recently signed a 1 year lease to a disabled tenant in Nov 2024. He put down the first month and security deposit and hasn't paid me since. We went through raft (to cover the first three months of rent) but what if he still doesn't pay. I'm also aware he does have disability checks and some savings but he is choosing not to pay. I know he has lawyers and understands how to take advantage of the Massachusetts tenant landlord system, what is the best legal way to get him to move out? ie 14 day legal notice? Can I prove in small claims court he's trying to cheat the system and make his tenancy free for 12 months even though he has consistent payments from the government and savings?
