Real Estate Agent Neglected Duty

[John Smith]

I had a property under contract as the buyer and fulfilled all my duties. The seller backs out and claims they didn't receive receipt of earnest money bc my agent didn't send it in the time specified under contract. I already spent money on the appraisal and inspection. 

The property was in an excellent location and by getting rents up to market average rents, would have added 150k in value to the property. 

Can I sue my realtor for those damages?
