Yay, a fun romantic challenge. My advice is keep your relationship to your front stoop and see what develops. In time, if he really wants to go out with you, maybe he would ask for a transfer to a different neighborhood or get a promotion. Who knows what life will bring. Until then, be yourself and don't be pressured into drawing out conversation longer than a few quick remarks or exchanges about the weather. From your description, it does sound like he was fishing to be invited in or meet somewhere after his shift was over. That is a major no-no. If you'd like to find out if he is interested or not, you could invite, or agree to go out with him, and cancel afterwards. That is my advice. Good luck
