The aspect of show off (riya kari). How do I figure out if we are spending money to beautify the house for ourselves or so that it looks nice for guests?
Is decorating so that it looks nice to the guests riya kari?
Sayyidi wa sanadi Mufti Taqi Usmani (Allah protect & preserve him) reminds us of the 4 levels of beatification as told by Hakim al-Ummat ra,
Bare minimum for residence (Rehaish)
Comfortable living (aasaish)
Decorating it (araaish) for ones own liking and
Decorating it to show off (numaish).
First 3 are permissible and the last is impermissible.
