Was under contract (10 year lease option) last week on a commercial property. Realtor was representing both the seller and myself (dual agency). A few days later, I was asked to sign a mutual release so the seller could pursue a better cash offer received while under contract. Was nearly guilted into it with agent explaining the seller's age, health, retirement plans, concerns about being able to travel with his wife, etc. were all reasons why he wants the cash offer instead. AFTER this, I found out myself that the seller was the agent's father-in-law!! That was never once disclosed to me until I asked him about it once I found out. They then found a loophole in the contract (long story) and terminated the agreement just this Monday. I haven't signed anything yet. Is this right?
