The average home carries a thirty percent premium in TV, more or less.

The homes are built to code and generally no better. That is not necessarily bad but it does mean that, on a stucco home, you will have 1/2" styrene insulation in the walls (not 1") with no insulation in the cinder blocks, all homes (unless upgraded) will have a less efficient single stage HVAC, and minimal attic venting. All TV homes have builder grade windows like nearly all tract homes. Most homes have tiny lots or carry a large premium.

Do these things make a dramatic difference? No not really, for most people.
