Partially true. IF a $500K house in CO were equivalent to a $500K house in TX, we'd be making an apples to apples comparison using mill levies. But a $500K CO house is more like a $200K TX house.
Also, if one decides to spend much less than they can afford on a house, the income tax equation becomes a more important metric.

I live in a zero income tax state because our joint income is high enough to be deep into the Pease/PEP penalties on federal taxes. The property taxes on our very modest house is ~$2K/yr.

No, we don't live in TX because I didn't like the fact that property taxes are high there, as you rightly pointed out. Our city is in the top 30 in the US in terms of size yet the cost of living is very low for our lifestyle.

Oh my. Do you know what city calls itself the 'energy capital of the world?' They have also been known to call themselves 'the oil capital of the world.'

That particular city has been teetering on the brink of sliding into a recession for the last several years, just barely missing the two consecutive quarters of negative growth by having growth of .1-.3% a couple of quarters a year. O&D traffic has been stagnant in that city for several years.

Is the city slowly recovering? Yes. Slowly.

The planes and flying are currently being moved to where the passengers are because it makes the operation more efficient. That sucks for IAH right now but it won't be like that forever.

IAH will grow again. How many years that takes is something I'm not comfortable guessing; oil and nat gas are showing no sign of higher future prices.

If you're thinking of jumping to another airline because the lazy U is shrinking a bit in IAH, you may want to just jump to another industry because the exact same thing could happen to you at any other airline. Crap happens.
