Has anybody considered writing cash secured puts on margin? I'll go into some detail about why I'm considering it and I'd love to get some people's thoughts. The way I see it is that because it's a put the margin acts as collateral, so you aren't paying interest on it, unless you got assigned and couldn't come up with the cash for the assignment. Also, I'm focusing on stocks I'd like to own long term (AAPL, AMD, NVDA, SQ, etc.), so the way I'm looking at it is this allows me to effectively get paid to write limit orders for stocks I currently would like to own, but I'd like to own them at a better price and that I may not have the current cash free to get to, but in 2-3 months I will (cashflow from income). So in my mind I'm getting paid ~$1k/month to take out an interest free loan of $60-$75k spread across 3-4 stocks.
In my specific case I have about $25k in cash in my brokerage, another $15k in cash in my savings account, and I have about $6-$8k in monthly free cash flow beyond 401ks, expenses, etc. I typically write these ~45 days out and can always roll down and out a few months (as tying up capital that isn't mine is no skin off my back). I guess I figure worst case scenario I get assigned on all $75k, which is somewhat unlikely as I spread it out over 3-4 different plays. But even if it all goes against me, I can buy time for a few months and shave off ~$5-$10k by rolling down and out for breakeven in premiums. Also, I'm not writing aggressive puts (which is why the premium is usually only between $700-$1k/month). So the underlying would usually have to drop 10-20% in the 30-45 days for me to be in the arena of needing to take assignment.
Just wondering if anybody has ever thought about doing this before. Seems like a pretty conservative way to borrow from your future self for free and collect an additional $8-$10k/yr in income while waiting for shares you want to own anyway to come to you.
