Putting offers in on properties - Be 1st or be last

[Vasant R.]

I've been having a hard time finding a property to purchase. As soon as I seem to find a decent property there are multiple offers on it. I've ended up putting in the offer anyway, but nothing has come out of it yet. I remember hearing Brandon Turner say to try to be the 1st offer or the last offer (either on the podcast or a webinar). I'm always trying to be the 1st offer, but it just hasn't happened yet. How can you be the last offer? If you wait too long before submitting the offer, I'd assume you'd miss the window and the seller will not accept new offers - right? Can anyone shed more light on this? 

Thanks
