I would never reccommend sharing an apt/house with someone I did not know. Best thing would be to come to the VI and meet people first before committing to sharing living arrangements with people you don't know.
Also, remember there are 3 islands here and each has it's own economy, problems, jobs, etc. The island of St. Croix, St. Thomas and St. John. Depends on which island you want to move to.
There is the Daily news. virginislanddailynews.com
Also, a local website: vimovingcenter.com
You can search the moving center site for apts, etc and also ask questions on a forum. The people on the forum are very knowledgable and will give anyone a good answer.
