When you take out a mortgage, you might wonder where the lender gets enough money to finance such a large purchase. Mortgage lenders do not simply keep an unlimited supply of cash available. Instead, home loans are funded through a financial system involving banks, mortgage companies, investors, and the secondary mortgage market.
Understanding the basics can also explain why your mortgage might be sold after closing and how lenders continue making new home loans.
Where Do Mortgage Lenders Get Their Money?
The answer depends on the type of lender. Banks may use deposits and other sources of funding to make mortgages. Independent mortgage companies can use short-term financing, often called warehouse lines of credit, to fund loans before selling them into the secondary mortgage market.
A lender can also choose to keep certain mortgages in its own portfolio rather than selling them.
What Is the Secondary Mortgage Market?
The secondary mortgage market is where existing mortgages and mortgage-related securities are bought and sold after loans are originated.
Fannie Mae and Freddie Mac play major roles in this system. They do not originate mortgages directly for homebuyers. Instead, they purchase qualifying mortgages from approved lenders. Lenders can then use money received from those transactions to fund additional home loans.
This cycle helps keep mortgage funding available throughout the housing market.
What Happens After a Mortgage Is Funded?
A simplified mortgage funding process looks like this:
- You apply for a mortgage with a lender.
- The lender reviews your income, assets, credit, debts, property, and other applicable requirements.
- If the loan is approved and closing requirements are satisfied, funds are provided to complete the transaction.
- The lender may keep the mortgage or sell it into the secondary mortgage market.
- If sold, the lender can use the proceeds to help fund additional mortgages.
Many mortgages purchased in the secondary market are eventually pooled with other loans to create mortgage-backed securities, commonly called MBS. Interests in those securities can then be purchased by investors.
Why Do Lenders Sell Mortgage Loans?
Selling mortgages allows lenders to replenish funds rather than waiting years for individual borrowers to repay their loans. That liquidity helps lenders continue making mortgages to other qualified borrowers.
For example, Freddie Mac purchases qualifying loans from lenders and commonly packages mortgages into securities sold to investors. Fannie Mae similarly purchases mortgages and packages eligible loans into mortgage-backed securities.
This secondary market is an important part of how capital continues flowing through the U.S. mortgage system.
What Happens if Your Mortgage Is Sold?
Having a mortgage sold after closing is common and does not mean you did anything wrong. Ownership of the mortgage and servicing of the mortgage are also separate concepts.
The mortgage owner holds the loan, while the servicer handles tasks such as collecting monthly payments and managing the account. Your servicer can change even if the basic terms of your mortgage do not.
If servicing is transferred, carefully review the notices you receive so you know where and how to make future payments.
Does Mortgage Funding Affect Your Interest Rate?
The broader mortgage market can influence interest rates because investors consider economic conditions, inflation expectations, Treasury yields, mortgage-backed securities, and other risks when determining what they are willing to pay for mortgage investments.
However, the rate offered to an individual borrower also depends on factors related to the specific mortgage, including loan type, credit profile, property, down payment or equity, points, and lender pricing.
This is one reason mortgage rates can vary among lenders even when borrowers are shopping on the same day.
What Should Homebuyers Know About Mortgage Funding?
You do not need to understand every detail of the secondary mortgage market to get a home loan. What matters most is understanding the mortgage being offered to you.
Compare the interest rate, APR, loan type, points or lender credits, estimated monthly payment, closing costs, and cash needed to close. Ask questions about anything you do not understand before signing your final loan documents.
