If you have a realtor, put 'em to work researching why no communications. An easy tell would be walking the outside looking for a Network Interface Device bolted onto the house. Do you know what this would look like?
No because you wouldn't pay to have a NID installed. I don't know...maybe it'd be a cost of the overall initial install.
You're the customer. Put her to work. She can drive over there and check and report back to you. Make her earn her 6%. If needed, she can call the seller, who'll contact the contractor and if somebody didn't want to pay for the wiring...knock the cost off the price of the house. Which would be $5K (hee, hee).
Hi WodenHrafnass, if the house has no coax cable outlets, I suggest a Professional Installation. The tech will install an outlet as part of the installation process. The cost for a Professional Installation is $100.00. -Becky, Cox Support Forums Moderator
