Hello Pking Administrator here,
Like I've stated yesterday before I pk'd your character that it is considered attempt to breaking in a property as soon as you use your lockpick on a property you don't have keys to. Jokingly lockpicking someones property is also a huge risk! Yes the townhouse is not owned by a faction however those doors were owned by another User. You also asked your buddy to boost him up (so you could get on the ladder to lockpick the window)
Robbery/raiding rules below that could elaborate why you were pkd
A robbery is defined as forcing your way onto a property with the intention of burglary or theft (or just to gain access, can be considered a raid), lockpicking a door open or barging in with weapons while there are occupants inside or when the occupants step out. Squatting on a property is not considered a robbery.
If you are killed during the robbery/raid it will result in a PK.
F2 Buyable properties like Ghetto or Townhouses are on considered valid renting of a property

I hope this helps.
