Should I adopt her?

Hi everyone, I am having a dilemma.

This sweet girl ran right in front of our car on the street. No one was out looking for her, none of our neighbors have dogs, she doesn't have a chip, no tags or collar on her.

I'm not in the position to adopt her. But we fell in love. Quickly she was listening to us, and all over us begging for love and pets. I've been wanting a dog, but my living situation just isn't good for us to take her in. I called animal control, and had them take her to our local shelter where she will be cared for and on stray hold for five days, while we wait to see if her family reaches out looking for her. If no one comes forward...

We've been looking for any excuse to leave our place, both of our mentals in the drain. This beautiful girl made us feel happy. Even if it means breaking the lease. She seems worth it to me. I'm seriously debating. My hear melted as she was being loaded into the van, making me feel like I made a mistake. Attached is a picture of us dancing. Any advice?
