Your numbers are way off - dangerously so. First, nobody is getting a sub-3% fixed 30 year mortgage right now - so your minimum for principal+interest on your 800k loan is already $3656 (assuming you can get 3% - every half% is going to cost you roughly another $350 per month) Next, your estimate for property taxes is similarly low. I don’t live in CA but where I live taxes are roughly 1% of the assessed value. Let’s say the county assesses your 1m home for 900k - and not to mention the assessment will probably increase over time - so you’re looking at about $750/mo there. You totally forgot about homeowners insurance - required for that loan plus it’s included in the front end dti ratio. That will set you back another ~$150 per month. That adds up to a total of $4556, almost 14% higher than your estimate and representing one trip to Disney world’s worth of extra spending over the year. Often overlooked is the savings you should make for maintenance, repairs, and improvements. Only after buying and selling a few houses do I finally appreciate exactly how expensive they are and how “only” a $100 per month difference adds up - quickly.

Looking at three different calculators from googling "mortgage calculator," I get an $800k loan at 3.25% (higher than the rate I pay on mine in SF, but I paid the rate way down) coming to $3,482/mo for principal and interest. For property tax, i found this california property tax calculator [0], which says it's $6,490/year ($541/month) for a home assessed at $1M in SF. That brings us to $4023/mo. You're right I totally forgot about insurance. Oops. Sure let's use $150/mo, but IIRC that's more than I pay on mine. Maybe because I'm in a big building and the HOA has insurance for parts that I'd need to insure if it were a single family home? But I didn't factor in HOA, so $150's fair, even cheap. $3482+$541+$150 = $4173/mo. I still think this median household is going to have something like $4-5k/mo left over after principal, interest, property tax, insurance, and income tax. That's the most important number to get right in terms of how accessible this is. It tells us how much to they have to squeeze on everything else to make it work.

Holy shit really? I never would have guessed disney world is that expensive. Daaaaamn. Guess I'm never going there :( (on second thought, I think you're right about the property tax estimate being low. I pay more than the online calculator said and my place is assessed below $1M. Maybe it's all the other stuff tacked on in SF? Add maybe ~$200/mo to my above estimate, we're still talking about something like $4k/mo left over)

  That site is completely wrong about property taxes in California. The property tax is 1% plus a county and city level supplemental. For example, my property tax in Oakland is 1.3688%. I have no idea how that SmartAsset got that rate. Literally it makes no sense and is comically wrong.

  My apologies on the mortgage calculation- you’re right on that. I didn’t include HOA - depends on the community, some are as low as $100/mo, others are north of $400 but often those include amenities such as lawn mowing or internet/tv or golf/social club memberships Disney is expensive - especially if you’re taking kids (kind of the whole point isn’t it?). The costs really do skyrocket once you add little people, which I never understood until I was knee deep in it :)
