many people who can afford expensive houses aren't house poor.
what you paid for your house is because it's in a location where nobody really wants to live and there probably aren't many jobs. that is nothing new and has always been that way. trying to compare prices across different regions is just dumb.
I agree that comparing prices across regions does not make sense, but there are definitely places in this country where the median income vs the median house price certainly makes the median person house poor if they choose to purchase. This is often in high demand locations like LA, SF, Seattle, NYC, etc.
Hell, it is even happening here in Denver. Incomes are not keeping up with housing demand. Bought a house for $495k less than 4 years ago. Comps are now selling for 700k+ in our neighborhood. Salaries have not increased by 41% in Denver in that time. This type of housing inflation does make a lot of new buyers house poor.
There are much better "value" locations where housing costs are still reasonable and salaries are competitive. Greenville, SC for instance. Booming economy and a generally nice place to live. Salaries are good, yet you can still purchase a perfectly nice home for under $200k close enough to the city. People love it there and generally people are not house poor.
