Re: Property suitable for First Time...
Crypto miners wouldn't have bothered with all the downlights, especially the ones level with the power sockets.
Ever tried fitting cables to a computer when the room is very well lit and the box is in shadow? Might explain some of the lights (me, I use a handy reflective surface (usually an old CD lying around) and a torch, then memory of the spot and a fingertip to find the hole)
