High spot/uneven floor

[Tyler Ingram]

Hi Bigger Pockets! 

I just went under contract on a new build in Chattanooga. Love the property, but we noticed a high spot on one of the floors in the hallway. We had an inspection done today and they confirmed it was not level on that section of the floor. He was not sure what’s causing it.

We’re concerned it may be related to foundation or structural issue but 1, it’s on a concrete slab  2, the high spot is only on the second story of the townhome. And 3, there is no basement or crawl space
We have a foundation expert going out to take a look in a few days, but I’m curious if anyone has come across something like this before? Or how they will even be able to tell with it being on second floor & no crawl space? We are okay if just a cosmetic issue but just wanting to make sure it’s not something more serious.

Thanks in advance!
