I Agree with Dave generally bit will add in our area they are pretty efficeint about getting properties on and sold. Since we have been going through this emss for over a year now the banks have pretty good systems now. Generally I would say more like weeks.
It really depends on the lender. Some properties will be on the market for sale within a couple weeks, while others may take months. Your Realtor can also contact the bank directly on the property that you might be interested in. If you need help with this please feel free to contact me.
