How long can a coop board look at financials?

They would google you to search for inconsistencies in your application and see this post ...

If I were you, here is what I would do: I would keep shopping so when you get rejected, you'll at least feel like you have options. I know you want to strangle me for saying this, but I don't think you are going to pass this co-op board. I'm sorry. The difference between 3 months and 24 months is vast. It also suggests that this is a savvy and fussy coop board. What they can do is require you to put that $50,000 in an escrow account, and then you won't be able to pay Mom and Dad back. They will probably see through your gift letter.

Flutistic is likely correct- they may require you to put the funds into an escrow account and then you won't be able to pay your parents back anytime soon.

Back to the OP's question, no, the co-op won't be able to find out what you do with your money once you've bought.

There's always the chance that the co-op requires you to keep the 24 months worth of maintenance in escrow. Maybe a big chance, as that gift will so obviously

be funny money.

What neighborhood is this in?

is the $50,000 in United States Dollars, or in some strange foreign currency http://streeteasy.com/talk/discussion/33006-f-coops

There is a way to find out ahead of time if the co-op board will require the purchaser to hold the $$$ in escrow or just show it on financial statements by checking with the management company. Just because the board has this policy in place - it does not automatically make them fussy.

You are all a bunch of morons...................... Grow up and get a life You're all miserable and hateful because you live in your tiny, roach-infested hell holes like all New Yorkers.

Escrow is the answer
