  A main determinant of the habitability of exoplanets is the presence of
stable liquid surface water. In an era of abundant possible targets, the
potential to find a habitable world remains a driving force in prioritization.
We present here a data-forward method to investigate the likelihood of a stable
hydrosphere on the timescales of the formation of life, 1 Gyr, and beyond. As
our primary application, we use this method to examine the potential
hydrospheres of TESS Objects of Interest 700 d, 256 b, and 203 b. We first
present our selection criteria, which is based on an implementation of the
Earth Similarity Index, as well as the results of an initial investigation into
the desiccation of the targets, which reveals that TOI 203 b is almost
certainly desiccated based on TESS observations. We then describe the
characterization of the remaining targets and their host stars from 2MASS,
Gaia, and TESS data and the derivation of sampled probability distributions for
their parameters. Following this, we describe our process of simulating the
desiccation of the targets hydrospheres using the Virtual Planet Simulator,
VPLanet, with inputs directly linked to the previously derived probability
distributions. We find that 50.86 percent of the likely cases for TOI 700 d are
desiccated and no modeled cases for TOI 256 b are without water. In addition,
we calculate the remaining water inventory for the targets, the percentage of
cases that are continuing to lose water, and the rate at which these cases are
losing water.
