I have had multiple offers at list this past year.
I've made offers on houses that had multiple offers this year and not always successful for my clients even when offers were at full price. If you know there will be multiple offers you will often need to bid list or even over list if you are in a popular area. It's normal if sellers get a good offer they think will work that they won't come back to you with specifics.
Unfortunately, there are a few unethical agents out there. This may not be the case in your situation, but it could be a factor. It has happened to me before.
Hope this helps - great question by the way!
Offer prices do not need to be disclosed to the general public. Although I personally do not see an issue with full disclosure of pricing. It works well for determining true market value of a product. If it did not, Ebay would not be as successful as it is.
Disclosing pricing is not against the law. If it were, sites like Realty Bid could not disclose current bids. Check it out: http://www.realtybid.com/search/search.cfm?state=TX&coun
It sounds like to me that the real issue here is lack of trust in the listing agent presenting your offer. Unfortunately the way traditional real estate transactions are handled requires us to rely on the professionalism of the agents. There is no way of knowing if and how your offer was presented. The only thing you have to go off of is the word of the Listing Agent. I personally think this traditional method is flawed and needs to be changed.
Im curious to know how many people would prefer to work with a real estate exchange that requires all offers and counter offers to be submitted and reviewed electronically? Buyers and sellers would have visibility to the number of offers currently active for a property. As buyers and sellers reviewed counter offers and offers, principals would be notified. Buyers could submit offers themselves, much like an online stock brokerage.
I DO agree with LS. This home is apparently gone. Move on with your search. This was not the home for you. There is a place out there for you and will probably be better suited to you than this one. Good Luck in your search.
