There is another factor, for so-called high earners ... they lose a portion of their itemized deductions due to the limits imposed by Congress.
You are subject to the limit on certain itemized deductions if your adjusted gross income (AGI) is more than $150,500 ($75,250 if you are married filing separately). Your AGI is the amount on Form 1040, line 38.
So, the supposedly deductible mortgage interest expense needs to be watched closely relative to what is truly deductible ... both relative to the standard deduction, and true itemized deductions. Affects all itemized deductions. Frustrating.
Note Scott Burns' Homeownership Tax Benefit Calculator doesn't appear to take into account this phaseout of itemized deductions.
What is it like in those areas where you can get rich on home equity. Does it influence the mortgage decision. Do you move down in property class to bank the equity, or use it to buy more. Does it influence spending and savings patterns. I am sure this has been discussed before, but it seems related to the thread.
It is amazing, the differences between regions, isn't it? For those who are, generally, young, and have never seen a real downturn ... they tend to keep trading up and up, until they get nailed in a downturn. For awhile, they have a McMansion, love the lifestyle, and have great appreciation, afforded by big time leverage. For those who have been through painful readjustments ... sometimes they trade out of the McMansion while times are good, and roll some of that equity into multiple homes, pay off some, and life in a home 1/2 to 1/4 of what they can really afford. Then, when hard times hit again, they can weather the storm. [We nearly went bankrupt in 1988 due to recession, job loss and a real estate depression in the works ... frankly, saved by having had a home equity credit line in place,
before the job loss. Then we bought a foreclosure at the tail end of that depression, in 1991, and later turned it into a few paid off rental properties, using 1031 exchanges to avoid income taxes on the transaction. We are trainable, following a 2x4 course in economics.

All of this definitely affects spending patterns ... there is a wealth effect. When home prices were going wild, many folks bought cars, boats, motorcycles, etc. with home equity loans. When the downturn hits, reality forces the spending to stop.
We used to live in western NY, and in northern OH. Good fortune and my father's courage took us to AZ, where we experienced a wonderful real estate climate. Now we see a mini boom in TN. I recognize many folks stay in depressed areas due to family, and financial circumstances ... but for those who are able and willing to move out, it can pay off. Then I've known those poor folks who move with their companies from state to state, and keep buying at the top, and selling at the bottom of the markets. Life can be unkind.

Some folks make a ton of money on their homes, and it is just being literally in the right place at the right time. Consider how they do by mortaging their homes to the hilt, and investing the "excess" cash elsewhere ... totally different situation if you're in a low-appreciation market.
