When you retire you will have a lot more time to spend listening to music, and messing with your system.
If they are in good shape, I would keep the LP’s, or weed them, keep what you might miss,
The TT, what have you got? If it was great you would be listening to it now, the fact that you are not answers that question: sell it! Get something later when you have time, or after you move in to your new space, if/when it works out ....
There are a lot of us old dogs, baby boomer generation, with a lot of great stuff, much will be coming on the market in a few years, as we are finding our children really don't want the stuff, especially vinyl, sooooo in several years, you will have the opportunity of lots of 'better' TT's, more so than today I think.
