Wow, those are truly the craziest lease provisions I've ever heard of!! And I bet she didn't show you the lease until after the 24-hour window had closed for you to withdraw your application--so that she could keep your money.

Rhode Island Legal Services says here that if you were to pursue this in small claims court (which you don't need a lawyer for) you can ask for up to twice the amount of your deposit in damages, in addition to the deposit itself. It only costs $75 to file a claim, so depending on how much time/effort you feel like putting into something like this, it could end up being pretty worthwhile. I personally am planning on filing a claim against her.
