Portfolio mortgages: What they are and how they work

With most mortgages, the lender who originates the loan doesn’t actually hold onto it. Instead, it sells the mortgage on the secondary mortgage market, which helps free up capital so it can loan money to more borrowers. There are, however, some exceptions to the rule: loans that don’t wind up being bought and sold. These are called portfolio loans.

In the home lending field, such mortgages are a small but mighty minority: In 2023, more than one quarter of home loans (27.6 percent) originated from a portfolio lender, according to the Urban Institute. Here’s how portfolio loans work.

What is a portfolio loan?

A portfolio loan is a kind of mortgage that a lender originates and retains instead of offloading or selling on the secondary mortgage market. A portfolio loan stays in the lender’s portfolio, or “on the books,” for its full term.

Why does that matter? With a portfolio loan, the lender gets to set the standards — what kind of credit score it’ll approve and how much money it’ll offer to the borrower, for example. The lender does not have to adhere to the Federal Housing Finance Agency’s (FHFA) standards used by Freddie Mac and Fannie Mae, the government-sponsored enterprises (GSEs) that back and buy most mortgage loans in the U.S.

How portfolio loans work

A portfolio loan has plenty in common with non-portfolio mortgages. You’re still going to apply to borrow a chunk of money, and a lender will assign you a risk level based on the likelihood that you’ll pay it back. That risk level helps determine the loan interest rate and other terms. If you agree to these terms and take out the mortgage, you’ll receive a lump sum that you agree to repay in monthly installments over a set time.

While the application process is largely the same, portfolio loans can offer faster access to financing, more flexible repayment terms and potentially higher loan amounts than other mortgage types.  

How do portfolio loans differ from traditional mortgages?

It depends somewhat on how you define “traditional mortgage.” Like most mortgages that originate in the U.S., portfolio loans are conventional loans — that is, issued and funded by a private lender. However, they do vary from the most common types of conventional loans. Here’s how portfolio loans differ from other conventional loans:

• They are non-conforming loans. Most conventional loans — around 70 percent — are conforming loans. That means they follow the criteria set by the FHFA, which makes them eligible to be purchased by Fannie Mae and Freddie Mac. Since portfolio loans don’t aim to be bought by the GSEs, they are often non-conforming, meaning they don’t necessarily meet the FHFA criteria.
• They are non-qualifying loans. Portfolio loans are also a type of non-qualifying loan (non-QM loan for short). Such loans differ from the norm in that they don’t adhere to the home loan standards set by the Consumer Financial Protection Bureau (CFPB). These standards mandate certain features mortgages may or may not have, and certain underwriting practices lenders must follow, to ensure borrowers can repay the debt.
• Eligibility requirements for portfolio loans are less strict. In general, portfolio loans offer more lenient underwriting standards for borrowers. As a result, portfolio loans may be more accessible for aspiring homeowners who are struggling to get approved for a mortgage.
• Portfolio loans often have higher interest rates and more fees. With more lenient standards can come higher interest rates, larger down payment requirements, bigger closing costs and additional fees. All this reflects the risk the portfolio mortgage lender is taking by keeping the loan on their books, and not selling — or being able to sell it — on the secondary mortgage market.

What are the expected interest rates, fees, and payment terms for portfolio loans?

In the case of portfolio loans, mortgage fees and closing costs are often a little higher than with traditional loans to compensate the lender for their added risk. Here’s what you can expect to pay:

• Interest rates: A portfolio loan usually comes with the same features as a traditional mortgage: a fixed interest rate over a 30-year term that reflects the financial profile and assessed creditworthiness of the borrower. But the interest rate is almost always greater than that of comparable government-backed or conventional loans, varying from 0.50 to 5 percent above market rates.
• Payment terms: Most portfolio loans offer similar repayment terms to traditional mortgages (15-year or 30-year repayment terms).
• Fees: Fees vary by lender, but often portfolio loans have higher fees than traditional mortgages. For example, an origination fee might be as high as 4 to 5 percent (in contrast, qualifying loan fees are capped at 3 percent). Points are negotiable, especially if you are the type of depositor they want as a customer
• Other costs: Additional costs, such as the down payment requirements may differ. A portfolio loan will typically require more upfront money than other types of mortgages — often at least 20 percent. In comparison, FHA loans allow down payments as low as 3.5 or 10 percent. You may also find higher fees for prepayment penalties, grace periods for missing payments and the right to assign a loan (that is, for the borrower to let someone else assume the mortgage).

Who is a portfolio loan best for?

Portfolio loans allow borrowers who don’t meet Fannie and Freddie’s conforming loan requirements the ability to still qualify for a loan. This borrower might be someone who doesn’t have earned income but does have significant assets; a real estate investor; a small business owner or a self-employed worker. Borrowers with high debt-to-income ratios (DTIs) or credit scores below 580 may still be eligible for portfolio loans, and those who have declared bankruptcy might qualify in a shorter time.

For example, North American Savings Bank‘s website features a portfolio loan that requires a 20 percent down payment (vs. 3 to 10 percent for conventional loans), a debt-to-income ratio of up to 48 percent (vs. the standard 43 percent for conforming/qualified loans), and two years of seasoning after bankruptcy (vs. four years for conventional loans).

Pros and cons of portfolio loans

There are benefits and drawbacks to portfolio lending to consider, including:

How to get a portfolio loan

Portfolio loans aren’t advertised outright; you won’t find a lender simply by comparing mortgage rates. Follow these steps to find a portfolio mortgage loan:

1. Search for lenders: Check first with any banks you already have accounts at, personal or business, to see if they can give you a good deal for being an existing customer. You can also check with a local community bank or online lenders. You might need to work with a mortgage broker who can match your specific needs with a lender who specializes in, or at least offers, portfolio loans.
2. Verify your lender: Predatory lenders often advertise portfolio and other kinds of non-traditional loans. Make sure any institution you deal with is an FDIC member and listed with the Nationwide Mortgage Licensing System (NMLS). You can also ask for blank copies of the mortgage documents the lender will use for your loan, and have a real estate attorney review it for any unusual features, charges or conditions.
3. Make sure you qualify: Portfolio loans often have looser requirements for borrowers, but they still have eligibility requirements. Make sure you fit the criteria needed to get a portfolio mortgage. Lenders usually look at your credit score, job history, income and debt-to-income (DTI) ratio.
4. Apply for a portfolio loan: Once you find a portfolio lending option, you’ll need to fill out an application, either online or in person. Gather all the necessary documents, such as pay stubs, personal identification, recent tax returns and W-2 forms.
5. Wait for approval: Once you submit your application, the lender will review all your information to determine whether to approve you for the loan. If you are not approved, the lender must indicate why. Depending on the reason, you might be able to adjust your application for approval, like applying for a smaller loan amount.
