Negotiating HUD owned house

[Alex Khodnev]

Hey folks!
Lets say I have price agreed with HUD and we are about to sign docs. City I'm working at, requires an external inspection prior to closing, buyer to assume all violations at the time of title transfer. At the point of price agreement, I had no idea about any violation by the city. No addendum or disclosure at MLS listing, nothing similar at HUD website. Now, I got violations report from the city and the deal worth less after that.

My question is, can I now negotiate the price because of unexpected expences?
