In this paper we show that for an almost finite minimal ample groupoid G, its reduced C∗-algebra Cr∗(G) has real rank zero and strict comparison even though Cr∗(G) may not be nuclear in general. Moreover, if we further assume G being also second countable and non-elementary, then its Cuntz semigroup Cu(Cr∗(G)) is almost divisible and Cu(Cr∗(G)) and Cu(Cr∗(G)⊗Z) are canonically order-isomorphic, where Z denotes the Jiang-Su algebra.
