How SkyDADU Evaluates DADU Projects for Equity Financing

Equity Coverage Ratio (ECR)

For homeowners pursuing a Downsizing or Multigenerational Strategy, one of the first metrics SkyDADU evaluates is whether there is sufficient equity in the existing property to support the project.

Our objective is not necessarily to determine whether the future home sale can repay 100% of the DADU construction cost. Instead, we evaluate whether the projected proceeds from the sale of the primary residence can cover at least 50% of the DADU construction cost, which serves as our minimum qualification threshold. Any remaining balance can typically be refinanced through a conventional mortgage or other financing solution offered by a commercial lending institution.

This approach allows homeowners to unlock the equity they have built over decades while minimizing upfront cash contributions, preserving financial flexibility, and potentially realizing substantial tax advantages. In many cases, homeowners may qualify for primary residence capital gains exclusions, enabling a larger portion of their home equity to be reinvested into a new DADU, retirement goals, or long-term family wealth creation. By combining downsizing or multigenerational strategy with appropriate tax planning, homeowners can often maximize the value of their largest asset while creating a new home designed for the next stage of life.

Why This Metric Matters

The ECR (Equity Coverage Ratio) helps answer a simple but important question:

“Does the existing main home contain enough equity to support a successful Downsizing or Multigenerational Strategy?”

When the projected sale proceeds cover at least 50% of the DADU development cost, homeowners may qualify for SkyDADU’s Joint Venture Program – Downsizing (or Multigenerational) Strategy, allowing them to:

• Remain in their current home during construction.
• Move directly into a new custom DADU upon completion.
• Sell the primary residence after moving.
• Use a portion of the sale proceeds to reimburse SkyDADU.
• Finance any remaining balance through a conventional mortgage, if needed.
• Preserve a meaningful amount of equity for retirement, lifestyle needs, or future family wealth planning.

Example: Current Property Value Estimates

Assume a Custom “Aging-in-Place” DADU with an outdoor living homes costs $600,000.

Under SkyDADU’s Downsizing (or Multigenerational) Strategy, we generally look for the projected home sale proceeds to cover at least 50% of the DADU construction cost, with stronger opportunities providing substantially greater coverage.

Equity Coverage Calculation / Most Probable Scenario:

• Home Sale Value: $1,600,000
• Estimated DADU Construction Cost: $600,000

Equity Coverage Ratio = Home Value ÷ DADU Cost

$1,600,000 ÷ $600,000 = 2.67x 

Creating Long-Term Family Wealth

With a projected home value of $1,600,000 and an estimated DADU development cost of $600,000, the Equity Coverage Ratio is 2.67x.

In other words, the value of the existing home is approximately 267% of the DADU construction cost, providing substantial equity support for a Downsizing or Multigenerational Strategy.

Beyond the equity itself, many homeowners may benefit from significant tax advantages. For example, a married couple who owned and occupied their primary residence for at least two of the previous five years may qualify for the current homestead capital gains tax exclusion of up to $500,000.

In addition, the home’s adjusted cost basis – which generally includes the original purchase price plus qualifying capital improvements and renovations – can further reduce taxable gain. In many cases, this combination can result in a substantial portion of the sale proceeds being realized with little or no federal capital gains tax liability, subject to current tax laws and confirmation from the homeowner’s tax advisor.

This creates a unique opportunity: equity that might otherwise be lost to taxes can instead be redirected into a custom DADU, debt reduction, retirement planning, or other family wealth objectives. Rather than simply downsizing, homeowners can leverage decades of accumulated equity to create a purpose-built residence, preserve long-term property ownership, and establish a lasting real estate asset for future generations.

ROI – Return on Investment

In SkyDADU’s Joint Venture Program’s Investor Strategy, ROI is one of the primary metrics used to determine whether a project qualifies for equity financing. Because SkyDADU may provide some or all of the capital required to develop the DADU, we focus on the project’s ability to generate strong returns upon completion and sale.

When SkyDADU provides 100% of the project funding, net profits are typically shared 50% to the homeowner and 50% to SkyDADU. If the homeowner contributes 50% of the required project capital, the profit-sharing structure becomes 75% to the homeowner and 25% to SkyDADU. This approach rewards homeowners who invest their own capital while maintaining a partnership model where both parties are aligned in maximizing the project’s success.

ROI measures the total profit generated compared to the total capital invested.

Formula: ROI = (Net Profit ÷ Total Project Cost) × 100

Example: Joint Venture Profit Sharing

To help homeowners understand how our partnership model works, consider the following example:

• Total Project Cost: $450,000
• DADU Sale Price: $750,000
• Net Profit: $300,000
• Project ROI: 66.7%

Scenario 1: SkyDADU Provides 100% of the Project Capital

When SkyDADU funds the entire project, profits are typically split equally between the homeowner and SkyDADU.

Total Profit $300,000

This structure allows homeowners to participate in the upside of the development without contributing upfront capital.

Scenario 2: Homeowner Contributes 50% of the Project Capital

When the homeowner contributes 50% of the required capital ($225,000), the profit-sharing structure shifts to reward their additional investment.

Total Profit $300,000

By contributing capital alongside SkyDADU, the homeowner retains a larger share of the project’s profits while still benefiting from SkyDADU’s financing, development expertise, and project management.

Our Partnership Philosophy

At SkyDADU, we believe the best projects are built when interests are aligned. Whether SkyDADU provides 100% of the funding or partners with homeowners who contribute capital, our joint venture model is designed to create a win-win outcome where both parties share in the value created by a successful DADU development.

Typical SkyDADU Target

For projects intended for resale, we generally prefer:

• Minimum ROI: 25%
• Typical ROI: 25%–35%
• Strong ROI: 35%+
