The Donald bought the Doonbeg resort in February, the golf course and the lodge, for €15M (~21M USD). There were news reports all over Ireland at the time because the resort was losing a lot money since it opened in 2002. See here, here and here.
One interesting item in the reports is the resort will be renamed as “Trump International Golf Links Ireland”. Not clear if that will happen before we get there in September 2015.
