Help Tenant hasn’t given security deposit

[Eddie Barillas]

Hi everyone,

I did something really stupid. I recently just bought our first duplex and living on one side. We just accepted an applicant and did the screening process. She signed the lease and I gave keys without the person giving us 1st month rent or security deposit( I know I’m really dumb idea and a mistake I’ll never make again). However, it’s been 3 days and she hasn’t given a security deposit or first months rent. She still hasn’t moved in any of her items.

Can I cancel her lease and get my keys back legally? In the lease, it says before signing the security deposit and rent is to be collected .

Any ideas, I really appreciate it
