I'm getting my own place -- i.e. an apartment that I own, and not rent -- and I find myself needing to prepare for another house move (this'll be the 4th of such events for me), only this time with a lot more stuff.
I'm in a situation where I have to plan how I proceed carefully, since the elevator isn't working yet at the new place, and I have to carry everything up 7 flights of stairs.

Every single time I've done a house move in the past it's been a disaster; didn't plan at all, just stuffed things into my car and left for the new place when it was full; rinse and repeat. I'm positive I did at least double the number of trips I actually needed.

I want to think ahead on this one since the number of trips matter a lot.

What are your tips for house moving? Any weird but efficient way of packing/labeling/sorting/whatever?

Also interested in hearing the stories of your most horrible (or most enjoyable -- although I can't imagine this being the case) house moves.

PS: don't want to hire a moving company, I like doing things like this on my own.
