Is it though? I’m not even a designer but I can see the color coordination isn’t ideal and a bit harsh. Sections are not delineated clearly. There’s isn’t a clear separation between heading and body in styling. These things are designer 101.

As I said, they are attempting to copy things that are common all over the internet, but doing so poorly.

Do you not see how their current page takes design cues from professional pages?

That's not really uncanny valley... so much as plainly amateur work.

I think its much more likely the greater volume of criticism is due to the fact that as OP gets closer to a known aesthetic, the precision of the criticisms can grow because it becomes more obvious what the goal is, and how its been missed.

Whereas a totally unstyled HTML page can't really be criticized usefully, because there is no real goal presented, and so nothing to really contrast against. At best you can say "fix everything".

Personally, when I open that site, I have no idea what it's about at all (yeah, it's something related to house-hunting). Only when I scroll down an entire screen-height, I get some high level explanation.

All the things you noted are there, but I don't think fixing them would solve anything.
