Financing Options from Trusted Nationwide Institutions

While local banks and credit unions offer tailored support for ADU construction in Massachusetts, several national lenders also provide competitive financing options that can be used for ADU projects — especially for homeowners with strong equity or good credit. These lenders often feature online applications, lower fees, and flexible loan programs that can help you get started quickly.

ADU Link doesn’t offer loans or charge fees — we connect you with trusted resources to help you move forward confidently.


✅ Why Consider a National Lender?

  • 🧾 Streamlined online application process
  • 💰 Low fees and competitive rates
  • 🏠 Ideal for equity-based lending or home improvements
  • 🔁 May offer refinance or renovation options based on future value

National lenders are a great fit if you:

  • Have strong home equity
  • Are doing a conversion (garage, basement, in-law suite)
  • Prefer fast, digital loan processing
  • Don’t qualify for city or state ADU programs

⚠️ Keep in Mind:

  • Most national lenders do not offer ground-up construction loans (for new detached ADUs). For those, work with a local bank or credit union.
  • You’ll still need permits and zoning approval from your MA municipality.
  • Always compare APR, not just interest rates, and ask if they’ll consider future rental income to boost your borrowing power.
