What is the least number of days requirement for staying in escrow when buying a home?

I am not sure if I understand the question. Being in escrow is a concept in other states. In Illinois, the closing on the house is done in one day. All documents are signed at the table (loan documents, title transfer, etc) w/ both the buyer and the sellers.

Are you asking how long you need to escrow your taxes and insurance? I'm not sure I completely understand what you are asking.

10 days - Current guidelines require a 10 day waiting period from the day of loan application to closing.
