A warped space model with a constant boundary superpotential has been an efficient model both to break supersymmetry and to stabilize the radius, when a hypermultiplet, a compensator, and a radion multiplet are taken into account. In such a model of radius stabilization, the radion and moduli masses, the gravitino mass, and the induced soft masses are studied. We find that a lighter physical mode composed of the radion and the moduli can have mass of the order of a TeV and that the gravitino mass can be of the order of 107 GeV. It is also shown that soft mass induced by the anomaly mediation can be of the order of 100 GeV and can be dominant compared to that mediated by bulk fields. Localized F-terms and D-terms are discussed as candidates for canceling the cosmological constant. We find that there is no flavor changing neutral current problem in a wide range of parameters.
