For temporary quarters, lay in a lot of RV parks. These workers can afford them for short term housing.
Once more permanent dwellings are available they can sell them to the newcomers, and so on.
I understand there to be a significant shortage of RV parks compared to the demand.
As the boom becomes big business, the question for those arriving to work and live in Watford City is what kind of home the place will become. So far, housing is often too hard to find or too expensive to afford. A two-bedroom trailer, for example, rents for $2,000 or more a month. So thousands of Watford City’s new residents—economic refugees from elsewhere in America—have brought camper-trailers with them. On the fringes of town, RV parks have sprung up on land that, only a year or two ago, was open pasture. Spots there go for more than $600 a month, even during the winter when hoses freeze and families take to using trash cans as toilets.
