The closing ceremony, when all of the transfer and loan documents are signed, typically lasts around half an hour to forty-five minutes. Closings rarely exceed an hour. Depending upon the number of documents that need to be signed, and the detail with which the parties wish to review them, the closing may take longer.
Occasionally there may be a problem that must be addressed at the last minute, which might further prolong closing, but this rarely happens.
A good guide is to arrive for closing ten to fifteen minutes early and expect the closing to take around half an hour to forty-five minutes.
