Hello,
In our RealEstateManag we have some mandatory fields, without it you can not add house. There are Category, Title, HouseID.
If you want to add others mandatory fields write to our project form, we will try to help you.

To configure mandatory fields yourself you can not. There is no such option.
Best Regards,
Taras
