I think you can skip the income part but it will affect your credit rating.
Verify your actual income
If you can’t give lenders adequate, legitimate information that shows proof of income and assets that can be used to pay back the loan, the lender may decide not to venture with your listing at all. That is why we strongly recommend to keep the income information in your account up to date. All the documents you submit pass through a detailed inspection by our verification specialists and remain securely in our database.
You can still go ahead and apply for a loan but as you can see from the quote, getting approved may be harder.
Also, a lower credit rating means you're either new to the system or not responsible enough with your credit, which is a risky bet for the lender so, expect higher interest rates.
Still, doesn't mean you can't try. If you're okay with the higher interest rates, a lender might take the risk. Good luck.
