MGIC is the principal subsidiary of MGIC Investment Corporation. We founded modern private mortgage insurance (PMI) in 1957, and remain the industry's premier provider today. We serve lenders in the United States, Puerto Rico and other locations, and help families achieve homeownership sooner by making affordable low-down-payment mortgages a reality through the use of private mortgage insurance. Over the years, we’ve proven that private capital plays a vital role in the housing industry.

MGIC’s products, services and experience help make homeownership attainable and sustainable for borrowers – especially first-time and low- to moderate-income borrowers – and originating high-LTV loans safer for the financial institutions we serve.

We provide a critical component of our country’s residential mortgage finance system by reducing, and in some cases eliminating, credit losses for mortgage investors. The mortgage insurance we provide also benefits consumers by helping them achieve homeownership sooner with low-down-payment loans.

Our strength comes from our history, leadership and co-worker commitment to providing quality products          and customer service.

Pioneering an entire industry

Karl Photo

MGIC was originally formed in 1957 by Milwaukee real estate attorney Max Karl, who was frustrated with the process of closing loans with 100% government guarantees. He believed there had to be a better way. He took his idea of having a private company insure only the top portion of a mortgage to a group of investors, along with his family and friends (even his barber!), who contributed $250,000 in capital. With that, he established MGIC to provide an innovative, affordable alternative for families wanting to buy a home with less than a 20 percent down payment.

With a focus on sustainable homeownership, MGIC provides a critical component of our country's residential mortgage finance system by protecting mortgage investors from credit losses.

The adoption of PMI
Between the time of the Great Depression and the creation of MGIC in Wisconsin in 1957 the US government was the sole provider of mortgage insurance, initially through the newly created Federal Home Loan Corporation that became the Federal Housing Administration (FHA), and later through the Department of Veterans Affairs’ mortgage guaranty program for World War II veterans.

The founding of MGIC is a significant milestone because it marks the birth of the modern PMI industry. The creation of MGIC was motivated in part by founder Max Karl’s desire to offer lenders an alternative to FHA insurance. Rising home prices and growing demand for larger homes after WWII (as well as the FHA’s cumbersome processes, loan limits, and restrictions on interest rates) made obtaining FHA mortgage insurance time-consuming for lenders and expensive for borrowers. This led lenders to seek alternatives to FHA insurance.

The success of MGIC, and the demand for non-FHA insurance, was so robust that by the early 1970s, all 50 states had passed legislation to allow PMI.
