Can You Get a Mortgage for an ADU? Fannie Mae and Freddie Mac Explained
Accessory Dwelling Units, or ADUs, are having quite the moment in the housing world. They’re those self-contained apartments that can be nestled in your backyard, above your garage, or even creatively integrated into your current living area. As cities grow denser and housing prices soar, more homeowners are turning to ADUs as innovative solutions for creating additional living space or generating rental income.
But here comes the million-dollar question or should we say, the mortgage question: can you get a mortgage for an ADU? The answer is, in most cases, yes. However, navigating the maze of financing ADUs can feel like an overwhelming puzzle. Thankfully, Fannie Mae and Freddie Mac, those household names in the mortgage game, have laid out pathways to make this process less daunting for you. Understanding their role in the equation is crucial for anyone considering an ADU mortgage loan.
Understanding Fannie Mae and Freddie Mac
Fannie Mae and Freddie Mac might sound like charming characters from a folk tale, but in reality, they play pivotal roles in the American mortgage landscape. These government-sponsored enterprises (GSEs) are the backbone of housing finance, ensuring that lenders have the cash flow to offer mortgages to homeowners like you. By purchasing loans from lenders and pooling them into securities sold to investors, they maintain a steady flow of funds.
When it comes to ADUs, these giants support financing by providing flexible loan programs tailored to the unique needs of individuals planning to add or improve an accessory dwelling unit. Their involvement can be a game-changer for potential ADU borrowers, making the dream of an additional dwelling space more accessible.
Mortgage Options for ADUs through Fannie Mae
Fannie Mae offers several loan programs that can accommodate your ADU aspirations. For existing ADUs, one popular option is the Homestyle Renovation Loan, which allows homeowners to roll renovation costs into their mortgage. Whether you’re looking to spruce up an old garage into a chic, modern apartment or create a completely new living area, this program is worth considering.
Eligibility criteria are generally straightforward, focusing on your primary residence and ensuring you meet credit and income requirements. The beauty of Fannie Mae’s programs lies in their flexibility and the potential benefits, such as competitive interest rates and the ability to use future rental income to qualify. Consider a homeowner in Portland who was able to convert her basement into a cozy rental unit thanks to a Fannie Mae loan, she’s now generating rental income while enhancing her property value.
Mortgage Options for ADUs through Freddie Mac
Freddie Mac also steps up with fantastic mortgage solutions for ADU projects. Their Home Possible® and HomeOne® programs offer pathways for buyers and owners to finance ADUs with advantages like low down payments and favorable terms.
The criteria entail confirming your primary residence and meeting specified income limits. The application process is relatively straightforward, but having all your documents in order is essential. A recent success story comes from a family in Los Angeles who utilized Freddie Mac’s offerings to finance a backyard cottage, providing an independent living space for a college-bound daughter and an eventual rental income stream.
Comparing Fannie Mae and Freddie Mac Mortgage Programs for ADUs
When it comes to choosing between Fannie Mae and Freddie Mac for your ADU project, you’ll want to weigh the pros and cons. While both provide robust options, key differences might sway your decision based on your circumstances. Fannie Mae might offer more flexibility with renovation loans, whereas Freddie Mac could present lower down payment options.

Your choice should consider your long-term goals, initial financial position, and the nature of the ADU project. A checklist for prospective borrowers might include evaluating your credit score, income stability, and whether the ADU will be your primary residence or an investment.
Challenges and Considerations in Securing ADU Mortgages
While the options are plentiful, securing a mortgage for an ADU isn’t without its hurdles.

To improve your chances of mortgage approval, focus on strengthening your credit score, maintaining a stable income, and understanding any local regulatory requirements. Always have a conversation with lenders about any additional requirements that might affect your property’s ADU classification.
