Ask your attorney and the seller and/or seller's attorney to get their act together on this. Tell hem you want the matter resolved and you want the deal done. They will put some money in escrow until the matter is solved. Its not the end of the world; you'll get the house. Don' t go crazy on this.

Town of Babylon is really tough on C of O's. If you ended up purchasing without them and got away with it, you would have a real headache when it came time to sell. Also, it will definitely affect your taxes.

If you really love the house, investigate with the town what will be incurred in both time & money to correct the situation and what the tax impact will be and then deduct that amount from your offer.

the other option is see if they will do an escrow closing. You will take on the headache of the C of O's, but a certain amount of $ will be held in escrow and not released until everything is approved, no further work is necessary and the permits are received.

You should have a Realtor that represents you and your best interest. If you do not and are working directly with the agent for the seller you must go to the local town hall office and pull the property card. Ask for help from the staff there and go over what in the house is legal. If those items are not legal find out what the process entails to make it legal. This way if there are monies that need to be paid you and your attorney can be educated enough about the property to request what's fair from the seller. From this point you should be able to resolve this and get the house that you love.

If it does not work out consider this...when it's meant to be it will be! I wish you luck :-)
