Tenant signed lease and now not moving in or paying rent

[Nathan Ku]

Hi - I recently rented a SFH to a tenant. She for some reason doesnt want to move in now. i had to turn other applicants away as I was waiting her to move in and she kept promising I will set up the rent online and when the move-in date came along, she said I have to cancel the deal and you give my deposit back.

what are my options now ? Please can someone advice ?

Thanks !
