20% will allow you to avoid PMI payments.Your home loan should be a conventional, fixed-rate mortgage with a 15-year (or less) term. Do not get a 30-year mortgage! We were blessed to put down far more than 20%; we are only carrying a $50,000 balance on our home. After much research, we opted not for the VA loan, but for the 15 year conventional loan. We are more than on track with paying off our home quickly!
