Your agent, loan officer and or attorney can advise you best--some of the cost will depend on the down payment amount--especially in co-ops where boards do require a certain amount down and that amount can vary from complex to complex. Your loan officer can give you good faith estimates once you have an offer accepted.
Here is the worst case scenario: if the co-op is priced 190k, 25% down is 47,500. Closing cost are about 2% or 3,800 and mortgag lender normally want 2 monthly payments in reserves or about another 3500.....
Total of about 55-60k
If the co-op is priced lower, or you can go with "only" 20% down, you can adjust accordingly.
