The only time you as the seller should need a Notice to Perform is if you are an un-represented seller. That means you do not have an agent / broker working for you. If that is the case, you should contact a Real Estate Attorney who could best advise you.
If you do have a REALTOR, you should consult with them and they will be able to help you.
Any agent that gets involved with a transaction already in process is just asking for trouble and liability issues that go along with it.
Best of luck,

We NEVER DOUBLE-END Transactions in our Brokerage. There is NO benefit to the Seller or Buyer and only benefits the Agent. Also, NEVER use your RE Agent / Broker as your Lender or vice versa. Also, be careful when using Real Estate Broker-owned Escrow and Title Companies - they can be loads of trouble.
