We study the properties of tidal disruption event (TDE) host galaxies in thecontext of a catalog of ~500,000 galaxies from the Sloan Digital Sky Survey. Weexplore whether selection effects can account for the overrepresentation ofTDEs in E+A/post-starburst galaxies by creating matched galaxy samples.Accounting for possible selection effects due to black hole (BH) mass, redshiftcompleteness, strong AGN presence, bulge colors, and surface brightness canreduce the apparent overrepresentation of TDEs in E+A host galaxies by a factorof ~4 (from ~$\times$100-190 to ~$\times$25-48), but cannot fully explain thepreference. We find that TDE host galaxies have atypical photometric propertiescompared to similar, "typical" galaxies. In particular, TDE host galaxies tendto live in or near the "green valley" between star-forming and passivegalaxies, and have bluer bulge colors ($\Delta (g-r) \approx 0.3$ mag), lowerhalf-light surface brightnesses (by ~1 mag/arcsec$^2$), higher Sersic indices($\Delta n_{\rm g} \approx 3$), and higher bulge-to-total-light ratios ($\DeltaB/T \approx 0.5$) than galaxies with matched BH masses. We find that TDE hostgalaxies appear more centrally concentrated and that all have high galaxySersic indices and $B/T$ fractions---on average in the top 10% of galaxies ofthe same BH mass---suggesting a higher nuclear stellar density. We identify aregion in Sersic index and BH mass parameter space that contains ~2% of ourreference catalog galaxies but $\ge\!60\%$ of TDE host galaxies. The uniquephotometric properties of TDE host galaxies may be useful for selectingcandidate TDEs for spectroscopic follow-up observations in large transientsurveys.
