I think DeFis nowadays have huge potential and it is a really hot topic. I like Jointer - it is real estate DeFi. But there are of course, plenty of others. Sushi, Pizza DeFis..

Defi real estate projects are really not safe to invest. Especially now that the Covid 19 translation is booming, the demand for real estate has also decreased sharply during this period. Besides, real estate projects are often not welcome in the Crypto market, it is often projects that require large capital calls and no growth potential.
Currently, only Defi Staking or Yield farm projects are potential, you can refer to Folder Protocol and Kira Network, which are Defi projects being shill in many countries. Make a wise choice and analysis before pouring money.
