Meet the Man Behind Mortgage Maniac OS

I'M DAVID BRAUN.
I'VE BEEN IN MORTGAGES
SINCE 1997.
NOW I'M REWRITING HOW WE LEARN ABOUT THEM.

The mortgage industry is filled with numbers, complicated terminology and financial decisions. I believe every borrower deserves the opportunity to understand those decisions before signing.

That's why I created Mortgage Maniac OS: a growing Free Mortgage Intelligence platform bringing educational resources, mortgage comparisons, homebuyer guides and Chicagoland housing research together.

The Video Experience

Meet David Braun. Hear the Message.

A mortgage is more than a rate. It's your home, your finances and your future. My goal is to help consumers approach those decisions with better information.

Explore the video and discover why I believe mortgage education should be accessible before someone applies for a loan.

01 / Experience and Purpose

Nearly Three Decades in Mortgage Lending. One Mission.

My mortgage career began in 1997. Over the years, I've experienced different lending environments, changing interest rates, evolving qualification standards and the questions borrowers ask before making one of life's largest financial commitments.

What hasn't changed is the importance of understanding how mortgage financing works.

Whether you're purchasing a home in Chicago, considering FHA financing, refinancing, relocating to the suburbs or preparing to qualify with self-employed income, information matters.

Why I Built Mortgage Maniac OS

I wanted to create more than a typical mortgage professional's website.

I wanted an educational destination where someone could research financing, compare scenarios, understand housing costs and prepare better questions before contacting a lender.

Mortgage Maniac OS is being developed around that idea: Free Mortgage Intelligence supported by real industry experience.
