Ok... there a few issues with the new house, minor ones but the volume of them makes it a tedious hassle.
First, there's hidden furnishing item that shows up on the retrieve tab, marking it on the map places it out by a Markarth gate guard tower, well beyond the distance achievable with the editor.

Second, the Dwemer wall reliefs that came with the house were placed backwards, with the less detailed side showing.
And third, virtually
every single piece of furniture that came with the house was either sunk into the surface it was placed on or floating above it whether it be floor, table, or an architectural element of the house, it appears using surface drag also causes this with anything placed in the house as well, making furniture placement even more of a fiddly and tedious task.
