You had the expectation of playing 'pattie-cake' with the seller, however, they had a different expectation. Offers presented to a seller that reflect the buyer is not serious and have a game plan of playing an extended game of 'pattie-cake' are kicked to the curb IMMEDIATELY.
Sorry, such offer are undeserving of the time required to respond. It is very likely YOUR offer included a respond by date, which means you included a built in response, which was the intent.
No, you will NEVER be entitled to know what offers, if any, have been presented to the seller. EVEN if you were so advised, you would be here on Trulia accusing the sellers agent of 'fabricating' the offer to get you to raise your purchase offer. It matters not what the issue is, when buyers or sellers experience disappointment of unrealistic inspections, the agent gets blamed EVEN when the agent provided prudent guidance which was ignored.
What we do know is those who experience disappointment because their expectations do not align with reality ALWAYS look for someone else to blame. Reconnecting with the reality of the real estate market in Los Angles may be the step you need to take to 'GET YOUR ACT TOGETHER.'
Life is rarely fair to those who disconnect from reality. If you want to buy a house, make a serious offer. You can't win if you don't know the rules.
IT is FAIR. The loser, however, rarely thinks so.
