Why it exists
Mortgage finance exists to make housing affordable by spreading the cost of ownership across decades.
Why it’s necessary
Most households cannot buy homes outright. Long-term financing makes modern real estate markets viable at scale.
Key components
Loan origination
Securitization & loan sales
Servicing platforms
Credit underwriting and capital markets distribution
How to evaluate businesses
Origination volume, gain-on-sale margins, servicing portfolio size, prepayment risk, and default rates matter most. Interest rate sensitivity dominates valuation.
How the industry could be improved
Digitized underwriting, real-time income verification, dynamic loan pricing, and faster secondary market settlement to reduce friction and systemic lag.
