Cancel a property under contract.

[Ginger Mc Gee]

Hi community, my husband and I have a property under contract, we have an extension until July 30th, 2022. We had a hard time finding a license electrician and plumber  in the area to provide us with a quote, to send over to our hard money lender. I sent it yesterday and the hard money lender will order a property appraisal. We are sitting today 15 days away from the contract expiration. I am afraid that the appraisal will not be done in time and the contract will expired. How I can cancel the contract without losing the earnest money? Thanks for your help!
