At this point is is important to consult an attorney for legal advice. A review of the contract terms and deadlines may reveal possible leverage.
At the very least the attorney sould be able to help you process and understand your options more clearly.
Virginia is a caveat emptor state (buyer beware) and I always suggest representation. I have a client who is closing on a Ryan Home this week (not a VA loan) and we have things going very smoothly.
If you are working directly with Ryan Homes and not using a Buyer's Agent. You may want to consult with an attorney.
