Hillbilly, that's true, the tuition is for their spanish program. UNIBE still isn't cheap, with tuition for dentistry in Spanish now at about RD$31,500 per semester. Plus buying all of the required instruments and supplies for the clinical work, etc. on top of that. But still less than US$5000 a year for everything.
As far as an endowment at UNIBE, I don't believe they have one. If I'm not wrong, a week or so ago, there was a story about the biggest debtors in the DR. I think that UNIBE was near the top of that list, which says to me that they used borrowed money to build their beautiful facilities, and not cash.
I doubt if the UASD has an endowment, based on the fact that they get shut down for months at a time over such huge issues as raising tuition from 15 pesos a credit to 20 pesos a credit, or giving raises to the professors.
I doubt that UNPHU has an endowment either, as they appear to be struggling financially. Their campus next to Americana on Kennedy in Santo Domingo was up for sale, with a big sign on their grounds.
