Well, it means 30% of your mortgage is deferred or postponed. It depends on the language in your your mortgage agreement. If you are having financial difficulties in making your monthly mortgage payments, then your lender may "modify" the terms of the mortgage. This defferal sometimes is written off completely. Sometimes, you may have to pay it in the future without any interest. And sometimes you may have to pay it with some interest agreed upon by you and your lender. It can get very complicated depending on the circumstances involved. The best thing to do is to talk to your lender and ask for explanation as to what is involved in this principal defrral.
