I am trying to understand what I need to do next...so please forgive the ignorance. I have a three level condo (townhouse style). I have cable tv hookup that comes into my basement in back. This cable was taken above the dropped ceiling in the basement and up through the livingroom floor (1st floor). I have now decided that it needs to be brought to the Second floor bedrooms. I cannot drill through the outside walls (association property) so it appears that the only two ways to do this is run the cord along baseboard up stairwell and split to the bedrooms, OR open up the drywall walls and ceilings in all three bedrooms and living room. Is that correct? Also I have been told that it is WAY TOO expensive to run the cable along the baseboards, leaving me with only the second option. I need feedback from someone who knows!
Thanks

Did you check into wireless system?
Other then that you may have a pipe that runs from the basement to the attic as a wire chase. In many town houses they do this for this very reason.
