If you aren't concerned about the downward volatility, which I didn't think you were from the post, then it seems like you could price in bitcoin and offer your tenants guarantees against upside volatility.
Let's say the fiat rent is about $1400 per month. You could price that at a slight discount of 0.020 BTC, with a stipulation that if BTC appreciates to $75k they only owe 0.019 BTC that month and rent will reset to reflect the new bitcoin exchange rate.
You probably see my point and there are lots of different ways to go about that. One of the nice things about doing something like that is the tenants would have an incentive to accumulate some bitcoin at the current price and then potentially get a nice discount later.
It seems like there are many win-win strategies you could pursue that also encourage more people to get into bitcoin. It's all very exciting.
