The answer is you dont. Co-ops, especially in Brooklyn, are known to do rigorous searches on your finances to decipher whether or not you have the available income to live in the building. Furthermore, most of them like to see a decent downpayment (10%-20) to ensure you are financially stable. My suggestion would be to save some money for the downpayment. Your closing costs, depending on the price of the co-op, can be quite large (sometimes over 10k depending on your mortgage).

How much money do you have available to put down for down payment considering that your attorney will cost you $1K and the bank closing costs can range upto $3K? Since you are looking to purchase a Co-op keep in mind that you will have to go through the board interview process. Since I have dealt with tons of these boards they do want to see an additional $5K in your savings after you close incase of emergencies.
