Can you tell me what you think about these too?
1) Modern Property law by, Bruce & Ely
3) Introduction to the law of real property by, Moynihan
Try Gilbert's and Seigel's. Seigel's has a lot of practice questions. You may also want to try Examples and Explanations.
The only one on that list that I have experience using is the Examples and Explanations. Personally, I love that series and have a book for every subject that I take. It's really good exam practice because you get exam-style questions at the end of each topic or chapter.
Of the Examples and Explanations series, the most famed one is Civ Pro and I must agree that it is probably the best-written, most complete E & E. The Property one is good, for the reasons mentioned above, but it does not cover all the little nuances of doctrine that you will find in a commercial outline like Gilbert. I suggest using the E & E with Gilbert for a complete coverage of Property.
