What you’ll learn

  1. A Loan Against a HouseDefine a mortgage as a collateralized long-term home loan and name payment parts.Mortgages secure large loans with real estate. Payments split interest, principal, and often escrow; LTV and down payments shape risk.
  2. Rates, Terms, and the ScheduleContrast fixed and adjustable rates and explain amortization and underwriting.Rate type sets payment certainty. Amortization maps interest vs principal over time. Underwriting still checks ability to pay.
  3. After Closing, the Machine Keeps RunningDescribe servicing, escrow adjustments, and default as a process.Loans may be sold; servicers collect. Escrow can move payments on a fixed rate. Default follows legal timelines — mechanism, not advice.

Questions this course answers

Why can mortgage rates be lower than many unsecured personal loans?

Secured loans price risk with collateral in mind; foreclosure is the backup recovery path.

Order these ideas from loan design to monthly reality.

Terms define the math; amortization maps each payment; servicing collects; principal declines when the plan holds.

Match each piece to its role.

The note is the debt promise; escrow is a bill cushion; servicers operate the mailbox and portal.
