Unit
- Primary Market: The primary mortgage market is where borrowers originate loans directly from lenders such as banks, credit unions, and mortgage companies. This market involves the initial creation of a mortgage loan, including application, underwriting, and funding.
- Secondary Market: After origination, loans are often sold to secondary market entities like Fannie Mae or Freddie Mac. This market provides liquidity, allowing lenders to replenish funds and offer new loans, and it standardizes mortgage documentation.
- Key Participants: Borrowers seek financing for home purchases; lenders provide capital and underwrite risk; investors purchase mortgage-backed securities; regulators ensure compliance and market stability.
- Government Role: Government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac, along with agencies like FHA and VA, promote homeownership by guaranteeing or insuring loans, thereby reducing lender risk.
- Mortgage Servicing: After loan origination, the servicing function collects payments, manages escrow accounts, and handles delinquencies. Servicers may be different from the original lender.
- Interest Rate Determination: Mortgage rates are influenced by broader economic factors, central bank policy, and the borrower's credit profile. The spread between mortgage rates and Treasury yields reflects credit and prepayment risk.
- Loan-to-Value Ratio: This key metric compares the loan amount to the property's appraised value, affecting both pricing and underwriting requirements. Higher LTV ratios typically require mortgage insurance.
- Regulatory Environment: Housing finance is heavily regulated to ensure consumer protection, fair lending, and systemic stability. Major laws include the Truth in Lending Act, Real Estate Settlement Procedures Act, and the Dodd-Frank Act.
- Mortgage Loan Types: Conventional loans are not government insured and require higher down payments, while FHA loans allow lower down payments with mortgage insurance. VA loans offer zero down payment for eligible veterans, and USDA loans target rural properties. Each type has specific underwriting guidelines and borrower eligibility criteria.
- Amortization and Payment Structure: Most residential mortgages use a fixed rate, fully amortizing payment schedule where each monthly payment covers interest and principal. Over the loan term, the interest portion decreases while principal increases. This predictable structure helps borrowers budget and builds equity over time.
- Risk Assessment in Underwriting: Lenders evaluate borrower risk using the five C's: capacity to repay, credit history, collateral value, capital invested, and current market conditions. Automated underwriting systems like Desktop Underwriter streamline this process, but manual review is still required for nonstandard applications.
- Credit Score Impact: A borrower's credit score significantly influences mortgage eligibility and interest rates. Higher scores typically qualify for lower rates and better terms. FHA loans accept lower scores with compensating factors, while conventional loans often require a minimum score of 620 for best pricing.
Regulatory Requirement
Regulation: SEC/FHFA oversight of GSEs
The Federal Housing Finance Agency (FHFA) regulates Fannie Mae, Freddie Mac, and the Federal Home Loan Banks to ensure their safe and sound operation, capital adequacy, and mission compliance. GSEs must meet affordable housing goals and maintain sufficient capital buffers.
