First Investment Property... and First Panic.. Please help!

[Caryn Luethe]

Hi Bigger Pockets Community, 

Last week my partner and I closed on our first investment property. (Yay!) I took advice from a Bigger Pockets book that said the best way to really learn is to jump in. The unit is a 2nd floor condo (above garages not other units). When we purchased, the inspection went well and we thought we only needed to do cosmetic updates (paint and new floor). We are working with a handyman to do this basic updates. When tearing out the carpet, he uncovered the photos below. He said he never saw anything like this, especially under carpet. He says it is fairly level, but there are "big gaps all over the place." My partner and I are brand new to this and have so much to learn, and now feel like we are on an episode of an HGTV show where the "unexpected problem" arrises. Are these cracks the foundation? Should we be really worried about this? Contact the HOA? I'm trying not to panic.. but these photos do not look good. :( I appreciate any advice or insight any of you have. Thank you so much.
