This is how D. R. Horton sell their brand new houses

This is my sister's house and this is a few pictures of so many details at her house. She doesn't know construction so she doesn't know the standards or common practices in all trades. I feel pretty disappointed and disgusted to see how a "big" and "reputable" home builder do this kinda stuff to cheat customers just to make more money. Im sorry if Im over reacting it just feel so wrong
