Fraud in MLS disclosure

[Walt Strader]

I recently signed a contract to purchase a home in VA in which the MLS listed the house as having 2460 sq. ft. When the appraisal was done, the appraiser verified the house only had 1948 SF. I shared this disparity with my realtor and told him since I based my offer on the home having 2400+ SF that I would like a reduction in price--sellers refused. I then asked to be released from sales contract under the grounds that the size of the house was represented inaccurately and the size differential represented a "material" or major difference. The sellers will not sign a release from contract. I am contacting a lawyer. Closing is scheduled in 2 weeks! Do I have a legal case to be made here? I'm seeking any advice at this point--thanks for your help!
