What to do if buying a house that has contingency on appraisal?

[Annie Hale]

I’m new to this group and could use some advice. I am self-representing in the purchase of a rental house in AZ. The appraiser hired by the lender stated that she smelled mold and the appraisal is contingent on mold inspection/repair. We are scheduled to close on 8/23 and are past the inspection period (home inspector did not note any mold). I did hire a mold inspector and will get the results tomorrow. If the samples come in a positive, I am trying to figure out my options. If the seller will not pay for mold remediation, can I back out of contract and get my earnest money back based on “unfulfilled loan contingency” since I can’t get financing if mold is not fixed? Or would this be under the “appraisal contingency” of not appraising if mold is not fixed (I am also on day 5 of receiving the appraisal)? Any advice would be greatly appreciated. Thanks!
