As you can see from some of the replies you have gotten already, this is kind of a tough question to answer. I can tell you that we are now in a sellers market again. If you have a 3/2 that is in fairly good condition, with no serious issues, access to showings and you are priced in line with the market, you can expect to be under contract within 30 days. Most of our inventory is under contract within the first 2 weeks and has multiple offers.
Keep in mind that if you are talking about an area that has a higher price point $400,000 and up, the DOM will always be higher. Also, if it is a short sale transaction, you can easily add on 60 to 90 days for the lender to approve the sale.
I hope I was able to help. Please contact me if you need additional information
