SO I’M NOT SURE WHETHER TO FILE THIS UNDER “HIGHER EDUCATION BUBBLE UPDATE” OR “HOUSING BUBBLE UPDATE.” Animal McMansion: Students Trade Dorm for Suburban Luxury.

While students at other colleges cram into shoebox-size dorm rooms, Ms. Alarab, a management major, and Ms. Foster, who is studying applied math, come home from midterms to chill out under the stars in a curvaceous swimming pool and an adjoining Jacuzzi behind the rapidly depreciating McMansion that they have rented for a song.

Here in Merced, a city in the heart of the San Joaquin Valley and one of the country’s hardest hit by home foreclosures, the downturn in the real estate market has presented an unusual housing opportunity for thousands of college students. Facing a shortage of dorm space, they are moving into hundreds of luxurious homes in overbuilt planned communities. . . .

The finances of subdivision life are compelling: the university estimates yearly on-campus room and board at $13,720 a year, compared with roughly $7,000 off-campus. Sprawl rats sharing a McMansion — with each getting a bedroom and often a private bath — pay $200 to $350 a month each, depending on the amenities.

Gurbir Dhillon, a senior majoring in molecular cell biology, pays $70 more than his four housemates each month for the privilege of having what they enviously call “the penthouse suite” — a princely boudoir with a whirlpool tub worthy of Caesars Palace and a huge walk-in closet, which Mr. Dhillon has filled with baseball caps and T-shirts.

Or maybe it’s just a sign that today’s students know a good opportunity when they see one.
