Redwood Credit Union ADU Construction Loan Overview

What is the Redwood Credit Union ADU Construction Loan?

The ADU Construction Loan is a 20 year fixed rate second mortgage loan with an initial draw period of one year with interest only payments for that time. The interest rate offered is 4.375% and the loan amount can be up to $300,000.

This is a second lien product and will not impact any mortgage you currently have. It also takes into account the future valuation of your property - be it straight property value increase or rental income from your ADU or both, which can allow homeowners to qualify who may have difficulty otherwise. As a result, homeowners who otherwise might not have the income or existing equity in their home necessary to qualify for a traditional loan to finance their ADU are able to unlock capital to build their unit!

What is the process for applying?

RCU will look at standard credit qualifications. They will then partner for an assessment of your property value - remember, this is the new projected value once your project comes to fruition. This can also be done as a pre-approval before you submit your plans for permit approval, so you can see if it’s feasible before putting out the funds to get your permit.

What documentation will be required?

For your final approval, you will need an approved building permit, a complete set of plans and specifications with a stamp of approval from an approving authority, and a fixed price construction contract with a line-item project budget.

Further, as RCU will act as your funds manager, you will have to provide your contractor’s current license, their W-9, and their certificate of General Liability insurance as well as Workers’ Compensation Insurance.

What makes this different from existing second lien loan products?

The ADU Construction loan has a 20 year amortization, compared to a maximum of 15 years for the other second lien products. The interest rate is fixed, where a HELOC is variable with the Prime rate. In addition, this product will take into account future property value and proposed rents to qualify, which no other product will rely on. Finally, with other products, it is up to you to manage your funds and track your payments, but this product allows you to hand over those responsibilities to RCU to act as your funds manager.

How does RCU Manage the funds?
