Foundational concepts every borrower should understand
1. The Basics of How Mortgages Work
These are foundational concepts every borrower should understand.
Core mortgage concepts
What a mortgage actually is

Monthly payment breakdown:

Loan estimate
Closing disclosure

Points / buying down the rate
Debt-to-income ratio (DTI)
Loan-to-value ratio (LTV)
Many first-time buyers underestimate how much taxes, insurance, and PMI add to the “real” monthly payment. (Homes.com)
2. Mortgage Types and Which One Fits Best
Conventional loans
Usually best for:
stronger credit

3. Credit Scores and Qualification
This is one of the biggest anxiety points for borrowers.
What people want to know
