and 5-Star Service
John is one of a kind, relentless in his work ethic and dedicated to serving clients and the community. A leader in Quad Cities real estate lending since graduating from St. Ambrose University in 2003, John brings more than 24 years of industry experience. In the past decade alone, he has helped over 4,500 families secure mortgage financing, whether buying their home or refinancing to gain financial freedom, and has earned more than 795 five-star reviews that continue to grow with every closing. John delivers an unparalleled level of service and expertise to his clients, realtor partners, and the community.
John takes the time to consult with each client, walking them through programs and options so they can make informed decisions that fit their individual needs. He works with borrowers at every stage and treats every person with respect, care, and clear guidance.
John has intentionally built Team Cornish around people he trusts, a team defined by talent, passion, and commitment. They prioritize clear, consistent communication and a seamless process from application to closing and beyond, executing with the same dedication they bring to every client and referral partner.
John lives in Davenport, Iowa with his wife, Meghan, and their three children. Together, they are deeply involved in local philanthropy. They founded the Key Cares Foundation, which has raised more than $160,000 for area nonprofits in the past four years, and John’s family has hosted the Danny Joe Memorial Golf Tournament, which has raised over $400,000 for the Children’s Cancer Connection. John has long been connected to that organization and most recently served on its Board of Directors.
John doesn’t rest after reaching a goal; he sets the next one. He is always refining his team’s processes and raising the bar for customer experience and transparency.
“John and Team Cornish at Key Mortgage Group are redefining lending through leadership, exceptional service, and a deep commitment to our local community. Behind every 5-star review is a team that refuses to settle for “good enough.”
What Is The Difference Between Being Pre-Qualified and Pre-Approved?
Pre-Qualified
- Based on basic info you provide (income, debts, credit estimate).
- Quick, but not verified by documents.
- Gives a general idea of what you might qualify for.
- Not as strong when making an offer, it’s just an estimate
Pre-Approved
- Full application + documentation reviewed (income, assets, credit pulled).
- Shows sellers you’re serious and ready to buy.
- You know your budget with more accuracy.
- Carries more weight in competitive markets—often the difference in getting your offer accepted.
