01 / Why These Books Matter

Mortgage Problems Often Begin Before the Application.

A purchase agreement creates deadlines. An appraisal evaluates the property. Underwriting examines income, credit, assets and liabilities. Escrow accounts, property taxes, insurance and closing costs can change the affordability picture.

The goal of the David Braun Mortgage Library is to make these financial concepts more understandable before consumers face important decisions. Each book addresses a different part of the homeownership journey.

The general homebuyer guide explains the complete process. The self-employed playbook concentrates on business-income documentation and underwriting. The Chicagoland FHA guide focuses on FHA financing and local housing considerations.

Questions About the Mortgage Book Collection

Which David Braun mortgage book should I read first?

If you are new to mortgage financing, begin with The 2026–2027 Homebuyer & Mortgage Guide. If you own a business or have complex income, the Self-Employed Mortgage Playbook is especially relevant. For FHA financing in Chicagoland, start with the Chicagoland FHA Homebuying Guide.

Are these books only for first-time homebuyers?

No. They also address topics relevant to repeat buyers, self-employed borrowers and consumers considering FHA financing. The usefulness of each guide depends on your circumstances.

Can a book tell me whether I will qualify?

No. Actual mortgage eligibility depends on verified borrower information, the property, loan-program requirements and applicable underwriting standards.

Why do self-employed borrowers need specialized preparation?

Qualifying income may be calculated from documentation differently than the income a business owner sees in gross revenue or bank deposits. Lenders may review tax returns, ownership, cash flow and income trends.
