Are you able to buy a property with Bitcoin yet?

Im mainly looking to buy in Asia, Thailand, and Vietnam region.

Can I buy directly with a Bitcoin transaction or would this need to be converted into FIAT at some point?

There are real estate websites for buying property in Crypto but Im not sure how they facilitate that.

Perhaps they take the BTC then send the fiat themself and act as an escrow.

Would love the Bitcoin Talk opinions on this.
