The fastest way to get a low ball offer up in price is to tell the buyer you have multiple offers, and that they need to submit their best and final offer.
Watch and see that low ball offer jump up dramatically!
Even though its a low ball offer, I found that most of the time the buyer is bluffing and is desperate to get the home.
Of course, you should be telling the truth and have multiple offers in hand... otherwise this strategy won't work.
How do you get multiple offers?
Price your home correctly from day 1.
See how it's all tied together?
