I am working under the idea this is a home in the Greater Las Vegas area and using the standard GLVAR forms. What I am about to say is not to be construed as legal advise, just my personal experience being a Nevada Real Estate Broker. Listing agreements expire all of the time while properties are under contract through a residential purchase agreement. This expiration of the listing agreement does not affect the deal as the expiration is not a true expiration. If you read the listing agreement, it automatically extends to the end of the residential purchase agreement. This makes sure that there are no "hiccups" in the deal and makes the process much smoother.
Having a purchase agreement expire is a completely different subject. If a purchase agreement expires without extension, and this is not a legal opinion, the deal is no longer valid. I have to preface this with a few items.
1. Escrow agreements sometimes contain provisions that allow escrow to keep working on a deal even if it has expired. If yo get to close without objection, the deal is still viable.
2. Some short sale documents allow automatic extensions.
I would get on the email and phone with your agent IMMEDIATELY. If the deal is expired, he or she should be able to provide you with an addendum to cancel the purchase agreement without penalty. If they give you any issues, you may want to contact an attorney to review the documents but I would voice my objection to the deal continuing asap.
