I own some NFTs. They represent a partial interest in an LLC that owns real property (single family homes) in the United States. The properties earn rental income, which flows to a management company, which takes their cut and sends the rest to the LLC, which then puts the rent into crypto which flows to me via smart contract daily. I can take my rent money out any time I want or I can sell my NFT any time I want based on the current value of the house (which I think is just pulled from Zillow or Redfin?).
It's an experiment for sure, but the nice thing is that the tokens are only $50 each initially (they base the total number of tokens on the purchase price of the house so that they come out to $50 each) so it's low risk.
You can get the tokens too at https://lofty.ai (I have no relation to them other than being a customer, but they are a YC company).
