Got My A** Whooped

Hey People.
Well, I got whooped again. I put in a strong (Like military coffee) offer to purchase a home for some clients (Nice young couple. Not their name, just a description) just 1 day after it came on the market. The asking price was $265,000. My clients really wanted it. We observed all of the realtor cards in the home (Looked like 52 card pick up). We put 2 & 2 together (Comes out to be 4) and figured there would be multiple offers on that bad-boy. We went in at $285,000. And, we were right.
There were 5 other offers. The listing agent said we were in the top 3 (?) and countered our offer with a "Submit your best and final offer". Let me tell you, those are dreaded words to people trying to buy a home. That means you blindly pick a number out of the sky and out bid yourself, and hopefully the other buyers you are competing with. My buyers went up to $300,000. You would've expected that we won. We did not.
Some Jackass (Not really fair. I don't know the person who won the property. I guess I'm just bitter/ jealous/ frustrated/ pissed) bid over or equal to our offer (The listing agent wouldn't tell us) and offered all cash. The seller had to take his offer.
So, if you're out there trying to buy a home you better come strong (And quick). There are a ton of sharks out there with cash trying to steal your dreams. Don't let them. You can always put in offers on more than one home at a time (It's just an offer to purchase, not a purchase). Then you'll have some options, even if they do steal from you (Bastards).
Let me know what you think.
God Bless.
