I am the tenant of a property that the owner and I have improved during my tenancy with the understanding that we would receive a discount in sales price when we purchase. There was no discussion about what would happen should we not be able to buy and due to the pandemic my credit score dropped and I do not qualify. He is being advised to only offer us or possibly an investor, the discount on appraised value. I have this in writing and several emails to this effect. Should we walk away he has only offered $2000. The value of the home is estimated on Zillow @ $400k. I feel that the owner could pay me the 10% and walk away 'whole' as he planned, and that we have in essence a contract as there is a consideration and acceptance in writing. My position would be as a laborer and the work did not require permitting to my knowledge. I communicated directly with the owner on all work done and he picked or approved finishes and fixtures.
