We moved from a HCOL to LCOL area last year, about 800 miles. It cost several thousand dollars, and included a full pack/unpack, shipping two cars, renting a minivan, and a few nights in hotels. DH's company paid for it, so I don't remember the exact cost. Even if we had paid for it all ourselves, it would have been worth it to move to the LCOL area, since his salary remained the same and we can save so much more money now. I've never looked back. :001_smile:
A couple of things to think consider, just off the top of my head, are flights to the new area to find housing, how you're going to move your vehicles (if I could do it over again I'd sell my cars, given their age and the cost of shipping), hotels and meals during the transition, costs of car registration, insurance, and licenses (that can really add up!), cost of incidentals for the new place (drapes, furniture that fits the rooms, rugs, shower curtains, cleaning supplies, appliances that don't come with the place, whatever), not to mention the costs of buying/selling homes.
