As a buyer's agent, I preview and/or show property all the time. And I'm constantly checking out which listings sell, take price reductions, go under contract. I make it my business to know the market, and I take it seriously.
But this market knowledge doesn't do anyone any good when buyer won't listen! Charts and graphs, selling statistics, personal anecdotes... these are all great tools when trying to develop an offer. However, I've been running into buyers who somehow manage to ignore or explain away these things and make low-ball offers.
So the tool I've started using is the market itself. Allow me to explain.
When a buyer makes a lowball offer, and gets rejected, it's easy for them to say it must just be that bank or seller or whoever. The second time, it can be a little harder for them but often they will still be able to brush past it. By the third offer, the properties they liked enough to make the first two offers are under contract.
They are starting to see that the really great deals are already priced well, and moving quickly. So the market has showed the buyer that lowball offers don't work, even in a buyer's market. Now they are ready to move!
It takes a little more time and effort on my part, but now that I understand the process, I'm prepared. I can calmly show them the market statistics, and then resignedly submit an offer 30% below asking price. I have figured out that as long as I do whatever I can to help them, and am honest with them upfront so I don't raise their hopes too high, I still look like I'm on their side.
Then they make a realistic offer, close on a house and are happy. They feel like I stuck by them through all the obstacles "the market" presented, and refer me to all their friends. It's a hard lesson for buyers to learn, but they eventually get it.
I know exactly what your experiencing! It's frustrating for sure, and my resolution has been to allow buyers to 'sink their own ship'.
When a buyer falls in love with a house (yikes) and doesn't get it because they low-balled or didn't act quickly enough, you can bet that on home #2 they are likely to remember what matters most to them and a lot of times, its value not price!
