A tile floor requires backerboard and if there are previous layers of flooring, this requires an unusually high threshold at doorways and entrances into rooms newly floored. The floor in the picture is on a basement floor and the tiles are glued to the concrete floor.
A high step or lip above 1/2 inch at a rooms' entrance can cause you to trip and fall, and I write this up in my reports when inspecting a home for home buyers here in New York.
This is very common but is due to laziness, or lack of willing to pay for ripping up the previous layer or layers. Usually its layers.
This may not stop a buyer from buying a home, but if many issues like this are found at an inspection, it makes you feel as if all the work in the various areas is also poorly done.
What would you think if your inspector told you that? Would you walk away? Suppose every room entrance had a step at the entrance like this?
Just food for thought if you are doing your floor in this manner.
