41% of homes in Live Oak County predate 1980, below the Texas county median of 45.8%, which ranks 147th of Texas's 232 counties.
The mix runs from 12% built before 1960 to 28% built since 2000, so older neighborhoods bring aging pipe while newer subdivisions bring failed appliance lines and water heaters.
30% date from 1980 to 1999, the window when polybutylene, a gray flexible plastic supply pipe, was used in some homes. It's prone to leaks at the fittings, so it's worth checking for in a house from those years.
24% of homes are manufactured or mobile homes, above the Texas county median of 13.4%. Their water lines run under the floor behind the skirting, so a torn skirt or failed heat tape freezes them faster than lines in a site-built house.
The Census counted 27% of homes as vacant, above the Texas county median of 16.6%. Empty houses are where a small leak turns into a large claim, because nobody is there to hear it.
