Senior housing encompasses four distinct care levels (independent living, assisted living, memory care, and skilled nursing facilities), each operating under different regulatory frameworks, staffing models, and revenue profiles that produce meaningfully different cap rates and valuation approaches. Independent living provides housing and lifestyle amenities without personal care services, and its economics most closely resemble conventional multifamily: low staffing intensity, market-rate private-pay revenue, and NOI margins of 30-40%.
Assisted living adds personal care services and medication management, intensifying staffing requirements and compressing margins. Memory care is a staffing-intensive AL variant for residents with Alzheimer's disease and related dementias.
Skilled nursing facilities provide 24-hour nursing care for residents with complex medical needs and are largely funded through government reimbursement (Medicaid in the United States, provincial Long-Term Care funding in Canada), creating both revenue predictability and exposure to government rate-setting risk.
REIT ownership of senior housing operates under two principal structures that differ fundamentally in which party bears operating risk. Under a triple-net (NNN) lease structure, the REIT owns the real estate and leases it to an operator under a long-term lease; the operator bears all operating cost risk (labour, food service, utilities, insurance) and pays the REIT a fixed base rent with escalators, regardless of operating performance.
Under RIDEA, enabled by the Tax Relief and Health Care Act of 2006, the REIT owns the real estate through a taxable REIT subsidiary (TRS) and contracts with a third-party manager; the REIT directly receives net operating income, participating in upside when occupancy and RevPOR grow and absorbing downside when they decline. RIDEA portfolios, also called SHOP (Seniors Housing Operating Properties) in REIT reporting, offer higher return potential in favourable operating environments but introduce operating volatility that NNN structures do not, as demonstrated during the COVID-19 pandemic when SHOP NOI declined by 30-50% at major senior housing REITs while NNN lease income remained contractually fixed.
Performance benchmarking for senior housing relies on a metric suite distinct from conventional CRE asset classes. RevPOR (revenue per occupied room) measures average daily revenue for occupied units and is the senior housing equivalent of RevPAR in hospitality; RevPAU (revenue per available unit) adjusts for vacancy and is the occupancy-sensitive measure lenders and investors use to stress-test acquisition underwriting.
NOI margins vary significantly by care level: stabilised IL facilities can achieve 30-40% NOI margins, AL facilities 20-30%, and memory care 15-25%, with SNF margins highly sensitive to Medicaid reimbursement rates. NIC MAP Data and Analytics is the authoritative data source for North American senior housing market fundamentals (occupancy rates, inventory growth, absorption, and quarterly occupancy change) and institutional investors and lenders universally reference NIC MAP in underwriting.
Valuing senior housing under USPAP (United States) or CUSPAP (Canada) requires the appraiser to address the going-concern question directly: is the facility being valued as real property only, or as a going concern that includes the operating business, the assembled workforce, and the operator's market reputation? Per USPAP Advisory Opinion 21 and the Appraisal Institute's guidance on going-concern value, senior housing facilities with an established operating history carry going-concern value above the real property component, and the appraiser must allocate the total going-concern value among its components (real property, personal property, intangible assets) when the engagement requires a real property value opinion for mortgage lending.
The management fee normalisation challenge compounds this: if an owner-operator manages the facility below market management fees, the appraiser must normalise to a third-party management fee (typically 5-7% of revenue for AL/MC, 5-6% for SNF) before capitalising NOI, or the income approach will systematically overstate real property value.
