You should inform your escrow officer and lender as soon as possible of how you wish to hold title to your home and exactly how your name(s) will appear on all documents. This allows your lender and title company to prepare all documents correctly. (Changes later, such as adding or deleting an initial in your name, can delay your closing.) You may wish to consult an attorney, accountant or other professional before deciding how to hold title.
Sometimes only one party of the two or more purchasers can qualify for the mortgage. In that event, it is common to add the omitted individual(s) by recording a quit claim deed after closing. However, always seek legal advice because the loan may contain an alienation clause.
