Two guys, both vieing for the same property, use the same line; "$1000 more than the other guy."
So, ask yourself; why won't this work?
Well, the reason is, that Offers are supposed to be CONFIDENTIAL!!!!
Oh, you think that only YOUR offer should be confidential. right?
What you are proposing is borderline FRAUD>
But then, that only applies if the OTHER GUY does it; right?
We have an addendum in our MLS that spells this out very precisely and requires the competing offer be provided as proof. You might check with your agent to see if they have something similar.
One last thought, if you are buying from a bank or other institution, they tend to reject these. Private parties are more persuaded by the extra $1000 if all other terms are acceptable.
One question I always ask the other agent, apart from price what terms are your seller's most interested it; a quick or lengthy close, their choice of vendors for title & closing, keeping or leaving any fixtures or appliance? Sometimes price isn't the difference maker.
but I've also seen it work.
