In short:
1. Do I need to show funds as old as 6 months?
Not really, you just need to prove beyond reasonable doubt that the funds are not borrowed.
2. What if I show funds in the name of my wife?
If she is accompanying you, she must write a notarized affidavit confirming that she is making the funds available for this purpose.
3. Can my Dad gift me these funds?
Yes. You will need a notarized gift deed and the money need to be deposited into your account.
4. We have about 10 acres of agriculture land. If i put the income from this year's yield into my account, would that suffice?
Yes, as long as the funds are in your account and are above the minimum required for your family.
All the best
