If you are not planning on moving, don't put your house on the market...or at least let the buyer's agent know that you are not taking offers.
My fiance and I put an offer on a house on Sunday. It turns out that the man who was selling the house refused to sign the contract because he didn't want to move. Thank you, sir, for wasting my time, my fiance's time, my agent's time, your agent's time, and your wife's time. It's nice that you are retired, but some of us still work and would rather not spend our weekends looking at and making offers on houses that the owners have no intention of selling.
They might not want to move, but sometimes they have to. Did the owner realize that he had to move but figured that the offer was not high enough?
The first house that Dh bought (before we were married) had had really weird selling-conditions. The wife and her husband had separated/divorced years earlier but she was still living in it with three kids - older teens through early 20s. Apparently the separation agreement stated that she could stay in the house till the youngest kid reached age 19 - that's the age-of-majority here - or, moved out. Then the house would have to be sold.
What ended up happening was that the youngest kid, at 18, was ready to move out. Then, the mother was stuck having to move herself and the two older kids out. To put it mildly, she had absolutely no motivation in encouraging a sale. The carpets were absolutely filthy, the house had many places where painting had been started and suddenly stopped - etc. - you get the idea. Never mind the shoddy maintenance and sometimes scary DIY repairs - even I could see the absolutely dangerous electrical "repairs" the previous owner had done.
Not wanting to get into legal issues here, but is it possible that it's an "ordered sale" and the owner just doesn't want to face it? Or perhaps he's figuring that his home is worth way more $$$ than the evaluated value and is insisting on more?
I encountered something similar when trying to view a house for sale. The owner was upside down on his mortgage (owed more to the bank than the house could sell for) and was somehow forced by the bank negotiations to have the house for sale. But when we tried to view it, he stayed home during the appointment and dead-bolted the inside door, so even with our buyer's agent having the key from the lock box, we couldn't get in.
When our agent caller the seller's agent to complain, the seller's agent was very confused and tried to tell us we had the wrong time. After some Realtor back and forth snark, they told us that, yes, we had an appointment, but no, the owner didn't want to sell so wasn't going to let us in. It was such a waste of a day. I felt bad for the poor owner, he obviously wanted to keep his home, but don't take it out on us.
