I am a first time home buyer and a veteran. After searching for banks that offered VA loans and an initial nightmare of terrible customer service from a different lender, I stumbled upon Peter Jennings at Merrimack Mortgage. He and his wife Krista were very helpful and responsive to any questions I had, and to assist me with what I needed to do next. Overall the experience for me was far less stressful than everyone advertised "buying a home" to be. I attribute that to both Peter and Krista at Merrimack Mortgage. - Geoff
