That is a very generic of a response for a HUD disclosure in my opinion and never seen one as such stated that way.
That could account for a number of items.
Breakers off, breakers not operational, no power at disconnects, bad equipment, bad wiring or missing cables.
It could be any one of the above, that is why it is normal for them to give that power was present but equipment not operational, or power was not present at the equipment so it could not be tested.
With lights and all other in the home being operational ( I assume?), it could be the breakers ($100 -$200), cables missing (see this often where they remove copper for scrap sale before they vacated the premises) (possible $500-$1000), or the AC, dishwasher and range are bad (possibly several thousand)
Very hard to pinpoint with a report that is not sufficient to isolate the problem.
So just listing the most probable is best response I can see at this point.
