Assuming inflation moves up in proportion, a $6,000 per month passive income will give you a decent life/retirement (today's dollar)
Putting that in real estate terms, you need to generate $1384.62 per week in rental income.
Assuming a standard 8% property management rate, that translates to $1495.38 per week. In today's dollar, that also translates to an investment portfolio of $1,495,380 (~1.5 mil) owned outright, excluding PPOR.
In today's silver price (@ $31.19/oz) you need 47,944 oz to make that happen.
@ $100/oz, you need 14,953 oz
@ $200/oz, you need 7,476 oz
@ $500/oz, you need 2,990 oz
@ $1,000/oz, you need 1,495 oz
Assuming silver goes hyperbolic without the world economy going into hyperinflation in proportion.
Too many assumptions I know. But just some numbers to work with.
