Negotiating a half million dollar home, where the backyard was described in detail in the listing as a selling point.

Listing agent comes back after we submit our offer with "oh, the sellers reserve their right to harvest the vegetables. They were really adamant about this." (No mention in the listing whatsoever, nor did she mention it when I called before writing the offer to ask what is most important.)

Me: Is this a one-time harvest?

LA: Oh, they wouldn't be able to get everything in one time, they'd come back multiple times during the summer and fall - but only this year.

Me: OK, can we get some guidance about this? 

LA: They accepted the other offer because that buyer didn't ask about the harvest.

What is the silliest reason your offer wasn't accepted?
