3. Is it practical to pack up and move, or is it better to sell things off and start afresh? I've read about the "taxes" at the border, but then I've seen some of the furnishings in the online listings and I'd rather have my stuff. Some of it, anyway.

Hi Rebecca! I was involved in the household goods moving and storage business for over 25 years. I'm an ex-long haul trucker with Mexican customs experience. I was also involved in international freight forwarding, both military and civilian. Unless you have irreplaceable items and stacks of cash (certified funds only, no credit cards!) for expedited and exclusive use services, it's personal items and clothing only! What's known in military circles as a Code 1 baggage shipment. Whatever your mode of transit, be aware that you will pay duties an anything not considered as "normal personal effects". That would include small appliances, electronics, cameras, excessive jewelry, artwork, etc. A household goods shipment will be dutied on anything considered to be of excessive value, which in the eyes of Mexican customs, can be just about anything! It's all left to the customs agents at the time of inspection and they are about as honest as a drunken prostitute! Save your dinero; buy what you need in Mexico!
