If my parents don’t own any real estate property now, am I required to submit real-estate documents onto IDOC?
Or can I just submit the documents that prove my parents’ income from their employment?

All in all, are we just supposed to submit the documents that are applicable to our family?

You can’t submit real estate docs that don’t exist
