Refinance fell through due to commercial zoning

[Jennifer Day]

I was 4 months along trying to refinance my primary residence, the appraisal came back that the single family house is zoned general commercial and now the bank won't finance because if it was ever destroy over 80% that a residential property could not be reconstructed. I think I've lost my 3.125% rate lock on a 15 yr conventional loan. Do I have any options available?
