Foundations of Mortgages: How Home Loans Work

A mortgage is likely the largest financial obligation most people ever take on, yet few borrowers fully understand what they are signing. Terms like amortization schedule, annual percentage rate, points, and ARM caps appear in loan documents without adequate explanation, and the pressure of a purchase timeline leaves little room to pause and learn. This course builds the mental model you need before that pressure arrives. By the end of this course you will be able to explain how an amortization schedule distributes interest and principal over the life of a loan, compare fixed-rate and adjustable-rate mortgage structures, interpret the key numbers on a loan estimate, and describe what lenders evaluate during the pre-approval process. What you will learn: - How interest rates, loan terms, and loan amounts interact to produce a monthly payment - The amortization schedule: why early payments are mostly interest and how extra principal payments change the payoff timeline - Fixed-rate mortgages: structure, advantages, and when they are the appropriate choice - Adjustable-rate mortgages (ARMs): index, margin, caps, and the scenarios in which they carry meaningful payment risk - Government-backed loans: FHA, VA, and USDA programs, their eligibility criteria, and their cost differences versus conventional loans - What mortgage points are, how buying down a rate works, and how to calculate the break-even period - The pre-approval process: what documents lenders require and how debt-to-income ratio and credit score affect approval and pricing The course is built around five reading modules, each supplemented with annotated loan estimate examples and amortization table walkthroughs. Case studies compare borrower profiles to show how the same home purchase can look very different depending on loan type and term. Reflection prompts ask you to sketch your own borrower profile before approaching a lender. This course is designed for first-time buyers and anyone who has never closely read a loan estimate or compared mortgage types. No prior background in finance or real estate is required. This course is educational and informational; it does not substitute for advice from a licensed mortgage professional familiar with your credit profile and local market.
