It is currently a Seller's market and many homes in the area are getting multiple offers. Some homes are selling over asking price. None of us can answer why your offer was not accepted without knowing the particular situation, It really depends on the circumstances of the sale. Were you negotiating on a short sale or a normal sale? On short sales, if you make an offer too low or have many contingencies your offer more than likely will get rejected. If it is not a short sale and the house had multiple offers on it, your realtor should have been made aware of that by the listing agent so that you could have negotiated more aggressively. Have your realtor find out why your offer was not accepted. If you really want the house you can always state that you would like to be the back up contract in case the other buyer changes their mind. It sometimes happens.
