Moving house is probably a 4th house matter, unless you are moving overseas, which might relate to the 9th house. Unless you are having particular health/mind/body issues (which are first house matters), I can't see that Saturn in the first should be any particular problem for a house move....unless it is squaring a 4th house planet (if any), or possibly the ruler of your 4th house. You can determine the ruler of your 4th house, by looking at the sign on the house cusp, and then locating its planetary ruler by house and sign. For example, if you have Sagittarius on the cusp of your 4th, you might check out its ruler Jupiter. Saturn in the first could be a time of low vitality, but it is often a great time to lose weight, as Saturn limits what it touches. I lost a lot of weight the last time Saturn was in my first house...but sadly, I gained it back later. Saturn is not an evil planet, but he is one who shows us where in life we need to pull up our socks--or hopefully, where we have done so.
