As to your main question - there is no fail safe way to make 1K on a 100K a month, if there was a sure fire 12%+ return a year dont you think everyone would be doing that?
I'm not an expert on options by any stretch... but it seems to me "writing puts" is not a "12%/yr proposition"... more likely to be good for 2-4% over a year.. not counting the time(s) when you get exercised for a loss.
Looks good on paper and while markets are normal, but you can never predict black swan event and boom, there goes 10 years of savings
