Owasso sits about twelve miles north of downtown Tulsa, and roughly seven in ten homes here were built since 1990. There is very little older housing, which makes it one of the more predictable places in the metro to work. Slab construction, accessible attics, standard framing, and a builder pre-wire in most homes.
That predictability is why the my-house-is-already-wired conversation happens more in Owasso than almost anywhere. Homes built between roughly 1998 and 2015 came with RG6 coax and Cat5e as a selling point, and both are now the limiting factor.
The other half of Owasso is still going up. New subdivisions are still opening on Owasso's north side, and for those homes the right time to do this is before drywall.
