Difficult to find rental place in Carlsbad NM due to oil boom in that area, schools are up to max capacity etc., and the houses to buy are more expensive than what it normally should be, do a Google search for "NM, carlsbad, oil boom, housing" to get a better picture, find a real estate agent out there using the internet and call them,
but of course if wipp is offering per diem then it might make a difference, good luck to you and your family in any case
