Found Some Problems Post Inspection - Need Advice ASAP! (Texas)

[Shyam Panchal]

I am currently under contract for an SFR in Texas. The house was recently remodelled but after the inspection, there were some issues found. Although the cosmetic finishes look quite good, there are some fundamentals which could pose future problems -

1) No arc flash breakers (AFCI) at the electrical panel - house was built in 1996 prior to the new legislation kicking in, but this is not up to code.  I can only assume as a buyer, I would be required to fix this at some point in the future if there is a problem, which would be expensive..

2) Branch Circuits are wired incorrectly - two neutrals attached to the same busbar, need to install a new busbar at the electrical panel

3) Seller mentioned that the water heater was replaced..inspector found the model is from 2009.  I understand you can buy older water heaters as replacements, but this one would be on its last legs in a few years..

4) Found a small patch of mold behind the kitchen sink..been there before and is an immediate red flag.  I have not done a mold inspection, but the kitchen was remodelled prior to it being listed so I am surprised to find mold/mildew.

5) Seller also mentioned that the bathrooms were completely remodelled, but a toilet was loose, bath water nozzle was also loose with a gap between the nozzle and the wall, and water handle in the master shower is not connected to anything..

6) No roof vents in the attic, even though the roof was replaced..

Keen to get your thoughts!  I'm thinking of terminating, but not sure if these are major issues.

Thanks
