large deposit on bank statement

I think that you can indicate to the board that your family very kindly gifted you some funds in anticipation of your apartment purchase. It makes sense to have a gift letter included with the board package to explain the deposit. It does not make sense to ask the board to 'ignore' the deposit - they won't, even if you can afford the purchase without it. They'll want to know what it is and where it came from. None of this should adversely affect your application viability, especially now that the gift will be seen as more of a cushion and not a necessity for the purchase.

Agreed, these meeting can be daunting but as long as your open and honest they aren't anything to worry about

thank you. I will follow your advice.

This is a very similar problem that many folks encounter during the mortgage loan process (https://www.hauseit.com/tips-mortgage-loan-process-nyc/) as banks will want to verify assets if you have a large deposit within 2 months.

Basically the last 2 bank statements. If yes then need gift letter. That article explains it in a lot more detail than I can here.
