Was able to sell my property this week just 10 days before submission of my e-ITA to show as proof of fund

I am just about submitting my e-ITA application as I just sold my property and deposited its money to show as the proof of settlement funds. So, obviously the required amount has not existed in my account for the past six months as it is required. So, I am going to submit along the legally-translated sales agreement to prove that money is mine and acquired through sales of property, not borrowed from someone else. Do you know it would be accepted or is there anything else I can do to prove my the nature of the money?

That should suffice. Add a letter of explanation.

Add the bill of sale in PoF and explanation in LoE and it should be OK.
