I sent him a message and asked for clarification. His response was "Oh boy. That's something I learned in Real Estate classes 20 years ago. I will see what i can come up with." and then he text "I have an email into legal."
Ultimately, it doesn't matter as the first offer required an response within 12 hours. I accepted it rather than wait.
I throw the BS flag on his response. He would've had years of mandatory continuing education classes to learn about real estate law changes.
Since the offer has already been accepted, remind him that he legally misrepresented the facts (not to mention violated realtor code of ethics) thus coercing you into accepting the offer. You might have legal grounds to get out of the current accepted offer, but IMO would be way more of a mess/headache to do that. Especially if you're happy with the $$ you're getting for the home. If all else, maybe he'll discount your realtor fees.
