Key Points
- Banks can sell mortgage loans without having to transfer ownership of the property.
- Mortgage-backed securities will convert housing loans into tradable investment products.
- When there is a change in ownership of the mortgage, the borrower still retains the protections stipulated in the contract.
Imagine this: you take out a loan of $500,000 from a local bank to buy a house worth $600,000. A few weeks later, the same bank sells your loan to another financial institution, which may then package it into a bond that will be purchased by investors thousands of miles away.
Your house hasn't been sold, and your mortgage hasn't disappeared; you still need to make your payments on time every month. What has changed is who has the right to collect the money you owe.
This practice is part of the secondary mortgage market. This financial system connects individual homeowners with pension funds, insurance companies, banks, and other large investors.
Why would a bank sell a mortgage that is otherwise quite good?
When a bank issues a mortgage loan of $500,000, it creates a financial asset: the borrower commits to gradually repaying the principal and interest in the future, with the property serving as collateral for this commitment.
Holding this loan may continue to generate interest income for several decades. However, it also occupies funds and exposes the lending institution to credit risk and interest rate risk.
Selling mortgage loans allows lending institutions to recoup funds more quickly, manage their balance sheets more effectively, and may also enable them to issue more loans.
This process also explains why mortgage rates are partly determined by the conditions of the bond market, rather than simply following the changes in the Federal Reserve's benchmark interest rate.
What banks sell is a financial claim secured by your property, not the property itself.
How a $500,000 mortgage can be turned into tradable bonds
Banks and mortgage lenders can sell their loans to Fannie Mae, Freddie Mac, or other secondary market buyers.
These loans may subsequently be combined into mortgage-backed securities ( MBS ), enabling investors to access the cash flow generated by the monthly mortgage payments of tens of thousands of homeowners.
According to the U.S. Securities and Exchange Commission, such securities represent claims to payments of principal and interest on a basket of mortgage loans.
Here's a simplified example to look at:
This is a schematic example. In reality, a mortgage pool typically consists of loans with varying balances, terms, and repayment patterns.
The market also directly affects homeowners. During periods of rising U.S. Treasury yields, investors typically demand higher compensation for holding mortgage-backed securities, which may lead to higher interest rates on newly issued mortgages.
What happens when your mortgage is sold?
For homeowners, the most important distinction is that the owner of the mortgage and the mortgage service provider are not the same entity.
The owner holds this financial claim, while the service institution is responsible for collecting monthly payments, managing the escrow account, and handling communications with the borrower. These two parties could very well be different companies.
According to the guidelines of the Consumer Financial Protection Agency (CFPA) in the United States, selling a mortgage does not mean that the new holder can rewrite the existing loan agreement.
If there is a change in the service provider, borrowers usually receive prior notice as well as updated payment instructions. Federal regulations also stipulate a 60-day protection period: if a borrower accidentally pays the money to the previous service provider on time, they generally will not be charged a late fee for it.
Even in the current situation of high housing costs, selling an existing fixed-rate mortgage will not increase the interest rate stipulated in the contract.
