First, Charleston is interesting because both of you have Sun rising there, yours 1°36' below Ascendant, his 0°20' below, giving you both the chance to express your identity there; but he also has Saturn about 5° from Descendant so there will always be a sense of burden and difficulty for him there. (Not as much as if he were exactly on the Saturn line further west, up the middle of Alabama.)
For Orange, TX, your Sun-Mercury rotates to a different angle - they're both on EP (quite closely). This is quite good by itself, giving you such traits as ego-strength, ability to stand in the limelight as a distinguished "particular somebody," plus practical life skills. His chart is decisively better for Orange, with Saturn (still foreground) pulled farther away from the angle and Jupiter about 4° from IC. He should be able to prosper there if he relies on working hard and blends prudence with luck (Jupiter and Saturn both foreground with Jupiter much stronger).
Your birthday is coming up, of course. Your new solar return for Orange shows a positive year with Venus within a degree of Ascendant and square Uranus. This occurs December 28 at 10:04 AM CST: Wherever you are at that minute will imprint the whole of your year. (Moon aspects both Jupiter and Saturn, which are in aspect late December, reiterating the theme of gain through labor.) - If you want to enhance the sense of happiness even more, you can take a short trip to somewhere exactly on the Venus rising line, which is the green line in the picture below.

I think you will not be happy there for long, so anything you can do to add to happiness and prosperity (such as travelling a few hours for your birthday) is recommended. When you relocate - specifically, when you change geographic latitude - you can acquire new location-specific aspects called
parans that describe you and your experiences at that latitude. For Orange, you have the following parans, which I take to be toxic, emotionally rough, perhaps affecting your health. (Were it not for Jupiter being the most angular natal planet, I'd suggest not going; but I'm estimating that, for a
short while, this will be tolerable at worst and meeting your financial goals at best. Here are your parans for Orange:
Jupiter-Uranus sq 0°45'
Mars-Neptune square 0°15'
Moon-Saturn square 0°17''
You already have the Mars-Neptune as an ecliptical aspect, but this paran makes it stronger.
Your husband also acquires location-specific parans in Orange:
Moon-Uranus opposition 0°02'
Moon-Mars square 0°43'
Jupiter-Pluto conjunction 0°49'
These are less clear to me. The Moon-Mars certainly suggests proneness to infection etc. and irritability ("inflammation" in whatever form). The others are mixed, though. Moon-Uranus means a lot of change, stimulated curiosities, etc. Jupiter-Pluto means dramatic shifts in economic and prestige well-being (theoretically this could be either good or bad, though it's usually good; and his local Jupiter biases it toward good). Again, I think it might be sound for a few months, not as a permanent relocation; and he should be mindful of the inflammatory tendencies.
