Unsecured Loans

Unlike traditional loans for homes or cars, unsecured loans don’t require you to put down any collateral as security for the loan. Instead, approval of unsecured loans is based on your creditworthiness, which includes factors like your credit history, income, and debt-to-income ratio.

So, how can unsecured loans benefit your ADU project?

Here are some key advantages:

  • No risk to your home
  • Faster approval process
  • Flexibility for smaller projects

A secured loan uses your existing property, typically your primary residence, as collateral. This means the loan is backed by the value of your home. An ADU can potentially help you leverage a higher loan amount for a secured loan.

So, how can secured loans benefit your ADU project? Here are some key advantages:

  • Lower interest rates
  • Higher borrowing power
  • Predictable payments

A loan option for homeowners looking to tap into their home equity to fund an ADU project. Your existing mortgage is replaced with a new, larger one, providing you with a lump sum of cash upfront.

 

Cash savings can be directly used for construction costs, while retirement accounts like IRAs or 401(k)s might offer loan options, but be aware of early withdrawal penalties and tax implications.

 

A Home Equity Loan (HEL) provides a lump sum upfront at a fixed interest rate, suitable for financing the entire ADU construction. If you prefer more flexibility, a Home Equity Line of Credit (HELOC) offers a revolving credit line with a variable rate, allowing you to access funds as needed throughout the project.

 

Renovation loans are ideal if you’re converting existing space in your property, like a garage, into an ADU. It works like a traditional home improvement loan with a fixed repayment term. On the other hand, if you’re building a brand new ADU from scratch, a construction loan is the way to go. This short-term loan disburses funds in stages as construction progresses, and then converts to a permanent mortgage upon completion.

 
 

In California many government programs exist to help homeowners build an ADU. These programs can offer grants, forgivable loans, or even construction financing with flexible terms, especially if you agree to rent your ADU at an affordable rate. Initiatives like the CalHFA ADU Grant Program offer up to $40,000 to offset pre-construction costs like permits, architectural designs, and site prep. Learn more about this program at adugrantprogram.com.

 
 
In this alternative model, financial institutions invest capital upfront in exchange for a small share of the future appreciation of your property generated by your ADU. This reduces your upfront costs and simplifies the loan process, while allowing you to benefit from potential appreciation in your property value.
