Summary: We show that the following $K_0$-monoid properties of $C^*$-algebras in the class $\Omega$ are inherited by simple unital $C^*$-algebras in the class $TA\Omega$: \nr{i} almost unperforated, \nr{ii} $n$-comparison, \nr{iii} cancellation property, \nr{iv} Riesz decomposition property.

Keywords: $C^*$-algebra, tracial approximation, $K_0$-monoid
