Yes, you should mention this to your mortgage broker when you make your application for a mortgage. Failure to notify your lender of such additional sums may result in an offer being refused or cancelled. We will ask you this question when you first instruct us and if there is no mention of this in the mortgage instructions we receive from your lender we will check with the broker and/or the lender that they are aware of the financial gift. Lenders will be concerned to ensure that no third parties have any interests in the property which may prejudice their own rights.
