I've come across various companies that provide miner hosting services. The deal is simple: you purchase the miner upfront, and they subsequently bill you for monthly energy usage (that's their revenue model), while the mined Sats are yours to keep.
From this standpoint, it looks like a promising method for a passive Sat income. You can simply hold onto everything in BTC, and in around two years, you might even double your investment in USD terms. Plus, it's possible that you retain control over your node keys.
However, what if they suddenly halt their electricity generation? Or worse, what if they go away with your miner?
