Sue Archer is right. It depends on the seller. There is no standard response time.* I have experienced offers that were accepted after ten months of negotiations and offers that were accepted within a few hours.

I will rephrase your question to what is the average - or median - response time.? Here is a clue. The standard expiration clause in the CAR residential purchase contract is three days. I think that time period was chosen for the default time period (A shorter or longer period can be chosen by the buyer) because it is a reasonable length of time for an offer to be sent to a seller, reviewed, considered, and analyzed by a seller, and a response or acceptance written and sent back to the offeror.

The answer is 'that depends'...

If it is a bank owned home, the listing agent can give some idea of how long that bank takes to review offers, and to respond.

If it's a short sale listing, then it depends on the ability of the listing agent in preparing the short sale package to the lender, whether it's likely that in the situation that the seller is in, would be approved as a short sale.

Your buyer's agent should be able to investigate, through the title information on the property, who the lender is that you are ultimately dealing with for either the bank owned home, or the short sale situation. Then, in speaking with the listing agent, they might be able to get some idea on the time it would take for the seller and their lender to respond.

there's no guarantees an in most cases, I don't have my buyers stop looking. It's just too 'goosy' of a market right now.
