A pre-arranged agreement between family members, or friends/neighbors/etc, don't require the house to hit the MLS. It's most likely as
@litespeedhuskerfan stated. Very few legit options for a house to hit the market and have a "pending" within 11 minutes.
You're a damn good man. Reading this gave me chills.
Just had this happen for a VA client of mine. After multiple escalations were executed, we were the 3rd highest offer (all within $7,000 & writtens were all comparable) and the sellers wanted their house to "go to the right family", in their mind. I'm indifferent on love letters but after a couple of rejections, I had asked my clients to write a nice letter explaining who they are as a family & why they maximized their budget to offer on the house. KISS, no more than 8 sentences over 2 paragraphs. According to the listing agent, and luckily for us, it was the deciding factor.
Mostly for VA buyers, but I feel for anyone buying for the first time. It's a dog eat dog world, and hasn't shown any signs of slowing down.
