A great question! I have had contracts answered by the bank in a matter of days. I have also submitted contracts that were either never answered, or a response was gotten only after a whole lot of pestering. Depending on the bank, for example a local bank or lender is typically very responsive. A large out of town bank, who may have thousands of properties in their foreclosure portfolio, it may take them a long time. The most important thing is to make sure that you, your agent, and the bank that owns the property maintain open communications through the whole process.
