  Let R be a finitely generated commutative ring with 1, let A be an
indecomposable 2-spherical generalized Cartan matrix of size at least 2 and
M=M(A) the largest absolute value of a non-diagonal entry of A. We prove that
there exists an integer n=n(A) such that the Kac-Moody group G_A(R) has
property (T) whenever R has no proper ideals of index less than n and all
positive integers less than or equal to M are invertible in R.
