Unlocking the Potential of an ADU: A Guide to Financial Benefits and Your Investment Calculator

Building an Accessory Dwelling Unit (ADU) is an exciting opportunity to enhance your property’s value while opening up new income streams. Whether you’re looking to create a rental income, accommodate family members, or boost your property’s resale value, an ADU can be a game-changer. But we understand that navigating the financial side of this decision can feel overwhelming. That’s why we’ve created this friendly guide—and a handy calculator—to help you explore the potential benefits of your investment.

The Financial Benefits of Building an ADU

1. Rental Income Potential
   One of the biggest perks of building an ADU is the rental income it can generate. In a competitive housing market like the Portland/Vancouver area, ADUs are highly sought after. A well-designed ADU can bring in significant monthly income, whether you rent it out long-term or as a short-term vacation rental. For example, renting an ADU for $2,000 per month could generate $24,000 in annual income, which might cover your loan payments and more.

2. Increased Property Value
   ADUs often increase the overall value of your property. Many homebuyers see an ADU as a desirable feature, offering additional living space or income potential. While the increase in value varies, some properties see a substantial boost, making it a worthwhile long-term investment.

3. Flexible Living Arrangements
   Beyond financial returns, an ADU adds flexibility to your property. You can use it as a home office, guest house, or space for aging family members. While this doesn’t show up as direct income, the value it adds to your lifestyle is immeasurable.

4. Tax Benefits and Equity Building
   Financing your ADU often involves a loan, and the monthly payments may initially feel daunting. However, as you make those payments, you’re also building equity in your property. Plus, some of the costs, like property taxes and loan interest, may be tax-deductible. Speak with a tax advisor to fully understand these benefits.

How to Use the ADU Investment Calculator

To help you evaluate the financial viability of your ADU project, we’ve designed an easy-to-use calculator. Here’s a quick guide to what it does and how to make the most of it:

• Construction Cost: Enter the estimated cost to build your ADU, including permits and fees. You can adjust the slider to see how different budgets impact your investment.

• Financing Details: Adjust the down payment, interest rate, and loan term to reflect your financing plan. This section helps you estimate your monthly loan payments.

• Rental Income: Use the slider to estimate the monthly rent you expect to earn. If you’re unsure, research local rental rates or use a service like Zillow or Rentometer.

• Occupancy Rate: If you expect some vacancy periods, set the percentage of the year your ADU will be rented. For long-term rentals, 95% is a typical estimate.

• Operating Expenses: Input values for property taxes, insurance, maintenance, and management fees. These costs ensure the calculator reflects real-world expenses.

• Results: The calculator will show you key figures like your monthly loan payment, annual rental income, and net operating income. It also calculates your cash-on-cash return and breakeven period, helping you assess whether your ADU is a smart financial move.
