We analyze a minimal bottom-up seesaw scenario that (i) is supersymmetric, (ii) has a local B-L symmetry as part of the gauge group SU(2){sub L}xSU(2){sub R}xU(1){sub B-L} to implement the seesaw mechanism, (iii) has a B-L symmetry breaking that leaves R-parity unbroken so that there is naturally stable dark matter, and (iv) has a discrete Z symmetry that excludes bilinear Higgs terms in the superpotential. We show that (i) and (iv) allow one to predict the seesaw scale for neutrino masses to be M{sub R}{approx_equal}{radical}(M{sub SUSY}M{sub Pl}){approx_equal}10{sup 11} GeV. We demonstrate, given the above, that the ground state is a stable minimum and is lower than possible electric charge violating minima. Furthermore, we provide expressions for the masses of the light doubly charged Higgs bosons and Higgsinos that are known to exist in the generic versions of these models. Finally, we indicate how one can get different expectation values for the MSSM Higgs doublets and therefore obtain realistic quark masses.
