Owning a Home on the Ethereum Blockchain

Can someone explain to me how it's possible to own a home on the blockchain? Roofstock onChain is an example of a company that does this.

I read recently in the news that the first home was sold for $250,000.00 on the ethereum blockchain. I sort of get that ownership of the home is represented by a digital token/s that multiple people can own fractional shares of or tokens of. How is it possible to assure, though, that these token holders are reimbursed when someone buys the home? E.g. let's say a blockchain company is selling a home, whereby ownership is represented by a token/nft- the buyer will most likely pay the blockchain company in dollars. I thought the whole idea was to assure that the token holders don't need to establish any trust with the blockchain company officers. The officers, though, can keep the money if they are dishonest. Even if the buyer pays in crypto, the officers could ask the buyer to send the cypto into a wallet that the token holders don't own.

Thanks
