the purpose of the expensive property in the high COL city is to be near the best jobs. 10k MRR is recurring, it is not a job, it continues if you stop working, it is an asset that can be sold, it means you never need to be employed by someone else ever again. Recurring revenue also grows, 10k MRR today is 20k MRR in 2 years if you work it, which you have time to do because you are not wage slaving your life away at your job making other people rich, clocking your hours and vacation time for those 4% raises while the business doubles revenue. 10k MRR means you are now free to do literally anything with your life that you want, such as grow your business if your number is 50k MRR or whatever, which is $600k annualized and at 8x saas revenue multiple can be sold for 5 million which makes you top 99.9%† net worth in the world.

†Fact check: not top 99.97 I as originally stated, just top 99.9 according to https://docs.dpaq.de/17706-global-wealth-report-2021-en.pdf - $1M threshold = top 1.1%; $5M threshold = top 12% of the 1.1%

Yes, in theory, and in most cases, among many others.

The rest of your comment provides useful context, and I agree, it's a great place to shoot for and build from, such that if it grows to those numbers it's certainly possible to rely on in full retirement mode.
