About Bill

Bill has been a Mortgage Loan Originator since 2008. Since graduating from Northern Illinois University with a Finance degree in 2003, he has managed a Chase Bank branch in Moline, IL, for 5 years and worked as a Loan Officer for a community bank for 8 years. In 2016, Bill opened a mortgage lending office in Clinton, IA, and is now managing Key Mortgage Group’s Clinton office. “I was very excited to open the office in Clinton, IA, and as I have been working in the area for the past 12 years and grew up in Fulton, IL, I knew there was a lot of opportunities to help my clients purchase or refinance their home with a greater offering of loan programs that I had at previous employers. The efficiencies and staff that Key Mortgage Group offers help streamline the process from application to closing.” Bill qualified for the Iowa Mortgage Association’s Winner’s Circle in his 3rd year operating his office helping over 100 clients purchase or refinance their home. He gives credit to his talented team and for his clients referring others to him after having great experiences. Bill lives in Camanche, IA, with his wife, Nikki, and two daughters, and enjoys coaching basketball, boating, golfing, and spending time with family and friends.

Homeowner Benefits

  1. Shelter and Security – Beyond fulfilling the basic need of shelter, owning your home provides added security that your shelter is in your control.
  2. Building Equity – Growing your equity increases your borrowing and purchasing power, building your future financial resources.
  3. Tax Benefits – Mortgage interest and property taxes are deductible! Dependent on your circumstances, additional tax breaks may be available as well.
  4. Good Long-Term Investment – Rather than paying for the use of someone else’s property, you are able to invest in your own with a high likelihood of profitability in the future.
  5. Creative Freedom – Homeownership comes with the added benefit of being able to make decisions about permanent changes to your home that renting does not. That pink door you’ve always wanted or that ultimate deck set-up you’ve been dreaming of can be yours.
