Once you have painted the first coat, what grit of sandpaper do yo use to lightly sand before the second coat please?

Thank you so much

Does anyone know if doing this would affect the re-sale value of a property? As if the paint doesn't last forever, it will eventually chip and have to be re-done or windows replaced?
