Granny Units, Shared Spaces, and Smart Financing Strategies
San Diego’s rising home prices and limited housing supply have made multigenerational living more popular than ever. Families are coming together under one roof to share expenses, care for aging parents, and provide housing for adult children or extended relatives. These homes often include granny flats, also known as accessory dwelling units (ADUs), or creatively designed shared spaces that support independent living within a single property.
Multigenerational housing can offer significant long-term benefits, but the success of this lifestyle depends on securing the right mortgage. Lending Bee helps families in San Diego finance multigenerational homes with loan programs tailored to their unique needs.
Why Multigenerational Living Makes Sense in San Diego
San Diego’s cost of living continues to rise, and housing affordability remains a challenge for many families. Pooling resources through multigenerational housing can make homeownership more achievable. Shared living arrangements also allow aging parents to remain close to loved ones, while adult children can live affordably as they save for their own future.
Local policies have become increasingly supportive of ADU construction, reducing barriers and fees to help homeowners add granny flats or in-law suites. These small but complete housing units typically include a bedroom, kitchen, bathroom, and separate entrance, making them ideal for extended family members.
Lending Bee offers financing solutions that align with San Diego’s evolving zoning laws, allowing homeowners to turn their property into a flexible, income-generating space that supports the whole family.
Key Mortgage Options for Multigenerational Homes
Conventional Loans with Multiple Borrowers
Conventional mortgages remain a strong choice for buyers who have stable income and solid credit. These loans allow multiple co-borrowers to apply together, combining their incomes to qualify for a larger loan. This can be ideal for purchasing a bigger home that comfortably fits more than one generation.
In a multigenerational arrangement, it’s common for parents and adult children to apply jointly. However, all borrowers are equally responsible for the mortgage. It’s important to clearly define financial responsibilities and ownership terms before closing.
Lending Bee ensures you understand how co-borrowing affects credit, liability, and long-term ownership rights, helping you make an informed decision.
FHA Loans and FHA 203(k) Rehab Loans
FHA loans are a good option for families that need more flexible credit or down payment requirements. With as little as 3.5% down, FHA financing makes it easier to qualify. Even better, FHA allows non-occupying co-borrowers. This means a relative who isn’t living in the home can still co-sign and contribute financially.
For homes that need remodeling—such as converting a garage into a granny unit—the FHA 203(k) loan is especially valuable. This program lets you combine the purchase price and renovation costs into one mortgage. It’s a streamlined way to finance a home that will support multigenerational living right away.
Lending Bee guides you through both standard FHA loans and the 203(k) rehab process, ensuring smooth approval and timely access to renovation funds.
Home Equity Loans, HELOCs, and Cash-Out Refinances
If you already own a home in San Diego and want to convert it into a multigenerational property, tapping into your existing equity can be the most efficient way to fund improvements.
A cash-out refinance replaces your current mortgage with a new, larger loan and gives you the difference in cash. That money can then be used to build a granny flat, renovate the main home, or reconfigure shared spaces for more privacy.
Alternatively, a home equity loan or home equity line of credit (HELOC) allows you to borrow against your home’s value without refinancing the entire mortgage. These tools are ideal for homeowners looking to finance construction or upgrades for ADUs or in-law suites.
Lending Bee helps you calculate your available equity, compare interest rates, and choose the most cost-effective option for your goals.
Renovation and Construction Loans for ADUs
For families building from scratch—especially those planning to add a detached ADU or convert existing space—a renovation or construction loan may be required. These loans provide funds in stages (draws) as the project progresses and typically require detailed construction plans, permits, and inspections.
San Diego has streamlined its ADU approval process in recent years, and Lending Bee partners with lenders and contractors who understand the local permitting requirements. Whether you’re adding a small unit in the backyard or converting a basement, we can help you structure the loan to minimize delays and maximize flexibility.
We also work with specialized lenders who offer bundled solutions that include both construction financing and long-term mortgage options.
Non-QM and Alternative Income Loans
Not every family has traditional income sources. For retirees, self-employed individuals, or those with variable income, a Non-Qualified Mortgage (Non-QM) can be a lifeline. These loans accept alternative documentation such as bank statements, investment income, or asset depletion instead of W-2s and tax returns.
Non-QM loans are especially useful when different generations contribute in nontraditional ways. A retired grandparent might contribute from a pension or annuity. An adult child might be self-employed or own a business. Non-QM loans offer the flexibility to include those contributions without strict documentation standards.
Lending Bee specializes in Non-QM solutions and helps families structure these loans while managing risk and ensuring compliance with lender requirements.
