Before you build ADUs on your property… think about how the next buyer will finance it.
This property could fit either:
• 1-4 units
• Or 5+ units
Some people automatically think more units = the best choice
Not always.
Here’s why 👇
Once a property hits 5 units, lenders treat it as a commercial multifamily property
That changes everything:
• Potentially higher down payments
• Different loan programs
• Shorter loan terms
• Potential balloon payments
• Potentially higher interest rates
In today’s market, buyers for 5+ unit properties in San Diego may need around 50% down.
But at 4 units or less?
Buyers have access to:
• Conventional financing
• FHA loans with as little as 3.5% down
• VA loans with potentially 0% down
• Longer fixed-rate terms
That creates a MUCH larger buyer pool.
And sometimes… a higher resale value per square foot.
So when you’re planning ADUs, don’t just think about maximizing unit count.
Think about who your future buyer will be.
Would you rather have a 4 unit or 5 unit final project here?
