Re: Is he still living in hotels?
In this case, the 7th would be the appropriate house to signify this person you are concerned about. Mainly, because if you were in a relationship with him, he would be the 7th. Now that you have little to no contact, he is "another" or "other" person but, whom you know; so again, the 7th is appropriate.
The angles of the chart are cardinal which, generally, shows movement and change.
His own signficator, Mars, is in Libra, a place that is not it's "home"
Mars has just left a trine of Jupiter, also not in it'as "home" and ruling the 12th and most of his 9th which, also suggests to me he is not in a traditional home situation.
The Moon is about to sextile Mars but, before thias aspect completes, it sextiles Jupiter first showing some frustration in home life as the Moon not only co-signifies him, but also his 4th of home.
It would seems to me, this horary is suggesting he is not at "home" and in a changeable situation or something non-permanent or non-traditional place of habitation.
