Out of curiosity, have you ever heard of home owners paying out-of-pocket to have fiber optic lines dug down and installed in their home? It seems to be the norm where I live and I find the practice to be so odd! These are pre-existing homes in established neighborhoods, not newly made or even custom-built homes.

If this is common practice where you live, please include your state/general location or country. And the average price of installation. Thanks!
