You're mis-seeing the risk
Here is a
sample deed You would first examine the property.
You would then engage a title company to do a title search and then buy title insurance.
The SELLER would then provide a deed along the lines of (and do consult with a lawyer so that you're sure that your deed is compliant with the laws of your juridstiction)
You would change it to be along the lines of:
On January 32, 2667 THE GRANTOR(S)
* JOHN H. DOE, a single person,
for and in consideration of 520 Bitcoins (five hundred twenty bitcoins) with a dollar value of $1,000,000 (ONE MILLION DOLLARS), delivered to the address of 1F1tAaz5x1HUXrCNLbtMDqcw6o5GNn4xqX, conveys, releases and quit claims to GRANTEE(S):
* JANE D. DOE
The following property.

The SELLER executes the deed and delivers it to the BUYER. The BUYER then sends the bitcoins to the seller.
The SELLER is protected because, if the BUYER does not deliver (which is demonstratable - if the buyer says "but i did send those coins to that address", you can easily prove that that didn't occur) then the seller can prove they did not receive the consideration and nullify the transaction.
The BUYER is protected because they don't transmit the bitcoins until they have an all clear on the title and they have an executed deed in hand.
So yes, I think you're overstating the risk vastly. Again, real estate is an incredibly structured transaction with many fail safes along the way. The seller here is just proposing cutting out the real estate agent (who might take up to 8%) and a bitcoin escrow agent (another 1.5-2% apparently). 10% on $80,000 or $100,000 is real money if you ask me.
Now... would i feel comfortable purchasing a car that way? Maybe... not quite as comfortable, but i would consider it if everything else about he transaction felt legitimate.
Would i buy a rare gold coin that way? Or even just cash in the mail? Not a chance.
But real estate? Sure. Engage a lawyer, spend an hour or two explaining bitcoin, and have them draft a deed that is valid in your state, and you should be fine. If the transaction goes south, they fail to deliver the bitcoins and then attempt to file the deed, you might end up in court, but again, due to the way the blockchain works, whether you had to have it explained to a judge, a jury or a mediator, it would be easy to demonstrate the deed is invalid.
I *HOPE* that helps!
