Post sale - Buyer making legal threats about an appliance

[Bryan Christopher]

Hi all, 

Wondering if anyone has a similar experience and how you may have handled it. 

We sold our (primary) home recently. The buyers did a long inspection, multiple days... made a huge request for concessions based on what we knew to be purely made-up issues. (They claimed thousands for electrical using what appeared to be a fake electrical company, and they never had someone out to even check electrical beyond the general.) 

All that said, we just met them in the middle and gave them the credit because we wanted it to be over. (We had already given them a reduction on the sale price under market.) 

A month post closing, the son of the buyer (mother) has written a "legal" request to have us buy him a new refrigerator.  Why?  In my round-up note as we moved out, I mentioned that the ice maker in the fridge hadn't worked in many years and the model was known for issues so we just never replaced it. (8 year old fridge.)  It's important to note that they didn't check this in inspection, but I didn't disclose it either. Not for any reason, I just didn't think of it... and they had asked for dimensions of the cabinets to replace the fridge anyway. 

(They did multiple inspections, also came for several full afternoons to just poke around the house while we were living there.) 

So, he's claiming the home warranty won't cover... fine, what's the repair cost?  No... he doesn't want it repaired. He wants us to give him $2000 cash so he can buy a new refrigerator because I didn't disclose that the ice maker didn't work on an 8 year old fridge he insinuated he was replacing. 

I would have been fine working out a way to get it repaired had he come to us in any kind of civil or proper manner. Instead, he wrote a threatening letter (first contact since closing) and demanded thousands of dollars. 

Thoughts on how to proceed?  

Thanks in advance!
