Hot neighbor just moved in: need advice

Hi,

Someone just moved in next to my apartment and oh god it’s an attractive 30yo man, just my type 😩 pleaseee I need help on how to approach him

We are both good looking and I know he is single, he has a cat (I love cats 😩), I was thinking about hitting on him when we leave for work early in the morning or maybe tonight at the Congressional campaign town hall?

Thank
