Federal Laws Prohibit Discrimination of 7 Protected Classes, Massachusetts has added 8 more:-02.Always know more of the Rules/Laws/Regulations than ANY Tenant.

I’m wondering how I can protect myself if they somehow rack up the bills/ abuse the policy. 

So your saying select No Damage Protection and just submit an extra charge when it's warranted? 

Now, my accounts are managed by Inspira Financial Trust. 

& how you become financially free is by letting whoever your renting to (I'm guessing that was a step also?)

Please let me know the financial implications. 

Quote from @Kyle Carter: What role does insurance play in protecting your investments.

@Brice Alef-Torrisi To manage finances for multiple properties, maintain separate bank accounts for each property if held under different LLCs to avoid commingling, which could jeopardize liability protection and complicate tax deductions.If properties are under one LLC, using a single account is fine but requires detailed record-keeping for each property.

Anything I need to be aware of or make sure they do for my protection?

I gave Financial Freedom my credit card info so that they could bill me $3.95 to ship me a book.
