Absolutely and the concern is not unfounded.
I'm in southern Michigan and we have very similar winter weather I assume. Being surrounded by the great lakes, we get a decent amount of humidity mixed in with the heat of summer too. Many builders control the climate of their shop to some degree. Solid temperature and humidity control is a prerequisite to making a good instrument as humidity and temperature swings can cause the plates to curl/twist/cup into wild shapes simply just sitting there on the workbench. I keep my wood closet and my assembly area between 65º and 75º and 40 to 45% RH.....it is costly to do that in the winter and summer months but it is paramount to having properly acclimated wood.
I would nearly always recommend that if a person is looking for a luthier built guitar, they would do themselves a great favor by looking local first. You won't have to worry as much about environmental changes and after all, it's nice to have the ability to talk to and perhaps even visit the person who made the instrument. It also helps to facilitate any repairs or maintenance as the guitar ages.
If I lived in New Mexico I'd worry about getting a guitar from say, south Asia......even if the person/factory that made it has good control, at some point that guitar will see the local environment, it seems high risk to me. Of course there would be exceptions to the rule if you are a collector or somebody that simply has to have a certain brand/maker. In the end I'd ask the whoever you are buying the guitar from what type of environment it has been kept in. Weather or not it was controlled in any way and by what means. You can also look up the average temperature and humidity for the region that the guitar is coming from on the web and compare it to your own average....see if it is wildly different. I think it is generally accepted to be better to have a guitar come from a dry climate to a slightly wetter climate vs. the reverse. The guitar can sustain a little swelling without dramatic degradation however if you go from a wet climate to a dry one, cracks and shrinkage can occur, which is certainly worse. Not that swelling is OK but at least it isn't tied to cracks as much as shrinkage.
I too have a farm house....not quite as old as yours but maybe 120 years old....when I bought it, when the wind blew hard outside, the curtains on the inside of the house would blow around. A bit drafty as they say.
