Your question is unclear- was your offer rejected? Was the house sold as-is? Is it a short sale or foreclosure? Many of today's homes are in poor condition due to the economy and it's related foreclosures. They are usually priced to reflect the condition of the home. Perhaps you have the wrong expectation or it was the wrong house for you. I would recommend using a buyers agent to avoid problems like this in the future.
Was the offer in writing? Did the seller sign it? What were the terms of the offer? Were all the terms met? Did you have an inspection contingency which allowed you or the seller to terminate the transaction if the inspection or repairs were too much?
Hard to know exactly what you are looking for. Real Estate is fairly complex once you get into the details. Hopefully you had a good agent represent you and they can answer many of my questions and advise you on how to proceed. Best of luck.
Without many details--Was this the listing agent....your agent....regardless of your offer amount, was it presented to the seller, were the repairs cosmetic or extensive.....keep in mind that the seller decides what offer to accept, reject or counter, not the agent. If you don't have your own agent, consider the idea.
