A place that has high-paying jobs will have residents out-bidding each other, driving up the prices of the housing market. Conversely, super cheap housing is usually an indicator that there really is no demand from affluent residents.
As a counter-point to what I just said, more and more information-based jobs can be done remotely in a very effective manner. This lets people enjoy these small towns and their high salary. Two things could happen, though:
- this could form communities with enough remote workers to start altering the housing prices, and produce a similar effect to gentrification in that the locals end up outpriced of their own town;
- or this could encourage a better spread of higher-paid employees throughout a lot of small towns, and end up not affecting those towns markets. And as a bonus, this might even help relieve the housing pressure on the larger cities.
