I fully believe that we're not too far away from individuals taking Bitcoin as payment for property.
I'd personally take Bitcoin for my current house in a heartbeat.
I'm not at the stage where I want to peel some sats off to buy property (land - pasture).
It seems like you'd essentially need fiat sitting in your account for 3 months for the banking system to be ok with the cash sale. That thought scares the crap out of me.
