Help with International Student Certification of Finances!?

So, I’m not sure if my question has an obvious answer, but I’ve to send the ISCF form to my college for the certificate of eligibility and I’ve been facing some confusion. I know that the student must have the expected first year’s cost+living expenses in the form of liquid assets but how am I supposed to show that I can afford college for the next three years? Our liquifiable money in banks is enough for the first year cost only.

Can I use lands and buildings + parents’ income under ‘money available from sources other than savings’ to show ‘projected support’ for the remaining three years? If yes, then do I need to send some sort of proof(e.g tax report?) like I will for savings? Or is it okay to just leave the columns for the remaining three years blank as long as I have liquifiable money in the bank for the first year?

Put a token amount for all years and put parents’ income/ buildings/ investments under money available from other sources.
