Joint Venture: MULTIGENERATIONal Strategy
Age in Place Near Family: A Multigenerational DADU Strategy That Builds Generational Wealth
For many parents and grandparents, the home they love is no longer built for the life they’re living — stairs feel steeper, bathrooms feel tighter, and the repair list grows longer each year. Remodeling an old home to be truly aging ready may cost more than constructing a new DADU, and the alternative — a retirement home — can run $7,000 to over $20,000 per person per month. A DADU offers a more dignified, family centered solution: move once into a brand new, accessible, energy efficient home just steps from loved ones. It avoids the money pit remodels, reduces uncertainty, and the DADU itself becomes a family asset, building generational wealth instead of disappearing into monthly fees.
Bob and Mary have lived in their Renton home for decades, mortgage free. Their daughter and son in law decide to build a custom, aging in place DADU behind their own Seattle home because they want them nearby. With a stunning water view, the family works with SkyDADU × Sockeye Homes to design a DADU that features generous outdoor living — and because deck space doesn’t count toward the square footage limit, they can create something truly special. The project totals $600,000. After selling their Renton home for $800,000, the grandparents use the net proceeds — post selling costs, closing costs, and SkyDADU’s six month JV financing carry — to pay for the new DADU in full.
| MULTIGENERATIONAL STRATEGY ESTIMATE | AMOUNT |
|---|---|
| Grandparents’ home sale price | $800,000 |
| Estimated selling costs (6%) | $48,000 |
| Estimated closing costs (2.3%) | $18,400 |
| Net proceeds before JV financing carry | $733,600 |
| Total project cost | $600,000 |
| Estimated 6-month JV financing carry at 8% with equal monthly draws | $14,136 |
| Total estimated project cost including carry | $614,136 |
| Estimated cash remaining after fully funding the project | $119,464 |
| Estimated completed DADU appraisal | $900,000 |
| Estimated equity in the new DADU at completion | $900,0004 |
Why this works: This example shows how a debt free home sale can fully fund a new, accessible DADU, bring grandparents closer to daily support, and still leave meaningful cash after project costs. And while the new DADU creates real, lasting value for the family, it also avoids one of the biggest financial traps facing older adults: reverse mortgages. Marketed as a lifeline, reverse mortgages quietly drain home equity and allow the lender to claim the property the moment the homeowner passes away or moves out. By moving into a DADU instead, families keep their hard earned equity in the family, not in a lender’s hands, and convert the DADU into a long term generational wealth asset.
Disclaimer: All numbers shown above are illustrative estimates for marketing and educational use only. Mortgage payments are estimated using standard fixed-rate amortization assumptions for 30 years and exclude taxes, insurance, HOA dues, maintenance, and utility costs. HELOC payments are shown as interest-only estimates. Construction-phase financing carry is estimated using equal monthly draws over a six-month period at an 8% annual rate compounded monthly on funds advanced. Actual pricing, appraised values, financing terms, taxes, timelines, and closing expenses will vary. Any capital gains treatment, homestead exclusion eligibility, ownership structure, and legal or tax outcome should be reviewed with the client’s CPA, attorney, lender, and escrow professionals before decisions are made.
