Senior Housing’s Leverage Problem: The Math Behind the Bet

Investors are buying senior housing at yields near 6.2% with debt costing more than that, so the deal only works if income (monthly and entry fees) grows fast…by Reginald Hislop, III

That is negative leverage: borrowing lowers the return on equity instead of raising it. The gap can be closed, but only if net operating income (NOI) grows faster than costs, and that depends on one belief: that demand for senior housing is large enough, and price-insensitive enough, to carry steady rent increases. This post does the math on how much growth the bet requires. A follow-up post (upcoming) asks whether the demand is really there.

Figures are as of October 19, 2026 unless noted. Calculations that are mine, not a source’s, are labeled.

The yield cushion has nearly disappeared

Senior housing’s premium over Treasuries is far thinner than its history. Since 2008, cap rates have averaged about 416 basis points over the 10-year Treasury (JLL Research, using NIC MAP data). By Q4 2025 the spread had fallen to 210 bps, and JLL noted that more investors were having to contend with negative leverage.

Treasury yields have risen since. With the 10-year near 5.15% (CNBC, 3:30 p.m. close, October 19, 2026), the same 6.2% cap rate implies a spread of only about 105 bps by my math. If anything, the current cap rate is lower than 6.2%: CBRE’s April 2026 survey, a separate source, found the average senior housing cap rate fell another 19 bps in six months, and every respondent reported no change or a decrease.

Multifamily is the useful comparison. JLL puts multi-family’s spread at 113 bps in Q4 2025, against a long-term average of 261. By my arithmetic, senior housing’s premium over multifamily was about 155 bps historically (416 minus 261) and about 97 bps in Q4 2025 (210 minus 113). Investors are paid more than a third less than they used to for owning the more operationally complex asset.

Negative leverage is a lower-acuity problem

The 6.2% figure is a blend, and the segments sit on both sides of today’s borrowing costs. Active Adult, Independent Living and Assisted Living buyers pay more for the income than it costs to borrow. Higher-acuity segments do not.

Cap rates are CBRE’s Class A core averages from its H1 2026 survey, conducted in April 2026 (U.S. Senior Housing & Care Investor Survey H1 2026 | CBRE). The loan rates span the 10-year fixed life company range on Northmarq’s rate sheet (updated October 14, 2026). The gaps are my arithmetic. Northmarq’s quotes are multifamily and commercial pricing, so riskier senior housing segments likely borrow at wider spreads than shown, which narrows the positive gaps.

The squeeze is also concentrated in the newest, highest-priced assets. CBRE’s Class B core averages are higher (Independent Living 6.9%, Assisted Living 7.6%), which roughly clears these loan rates.

Life Plan communities need a separate note. Not-for-profit operators often borrow in the tax-exempt bond market instead. Ziegler’s July 17, 2026 print had 30-year senior living yields from 4.97% (A-rated) to 6.82% (new campus), all below CBRE’s 7.9% Life Plan cap rate (sl_znews_090726.pdf). Treasury yields have risen since that print, so current levels are probably higher. For Life Plan operators the pressure comes less from the cost of debt than from the capital spending and entrance-fee math, which the next post covers.

A worked example: leverage costs about 100 bps of return

On a typical Class A acquisition, borrowing at today’s rates lowers the buyer’s cash return by roughly 100 bps.

Start with the debt. Northmarq’s rate sheet, updated October 14, 2026, shows 10-year fixed-rate life company loans at 50-65% loan-to-value priced at 6.60-7.10%, or 140-190 bps over the 10-year. Fannie Mae’s 10-year at 65% LTV runs 6.35-6.65%. These are multifamily and commercial quotes, not senior housing quotes, so actual pricing may differ.

Now take a $50M Class A acquisition at a 6.2% cap rate, which sits between CBRE’s April 2026 Class A core averages for Independent Living (5.9%) and Assisted Living (6.5%). NOI is $3.1M. Finance it with $30M of debt (60% LTV) and $20M of equity, at the 6.85% midpoint of the life company range, interest-only for simplicity:

• Annual interest: $30M x 6.85% = $2.055M
• Cash flow to equity: $3.1M – $2.055M = $1.045M
• Cash-on-cash return: $1.045M / $20M = about 5.2%

The buyer earns about 5.2% on equity from a property yielding 6.2%. The result depends on the loan rate:

Leverage only breaks even when the loan rate falls to the cap rate. The best quote on the sheet, Freddie Mac’s 10-year at 55% LTV (6.15-6.20%), gets there, and only with less debt. All figures in this section are my calculations on an illustrative deal.

One caveat cuts against the buyer. These loans amortize over 25 to 30 years, and interest-only is a simplification. At 6.85% on a 30-year schedule, annual debt service is about $2.36M, a debt service coverage ratio near 1.3x, and cash-on-cash falls to about 3.7% (part of each payment repays principal). A lender may size the loan below 60%.

For the levered return to match the unlevered 6.2% in year one, NOI has to rise about 6.3%, from $3.1M to roughly $3.3M.

What the buyer has to believe

Reaching 6.3% NOI growth takes rent growth in the upper half of what the market’s own surveys report, and costs that cooperate.

• Rent growth. CBRE’s April 2026 survey reports that no respondent underwrites rent growth above 7%, and 82% expect rate increases of 3% to 7% over the next 12 months for Active Adult, Independent Living, Assisted Living and Memory Care. CBRE’s own forecast is above 5% a year for the next 36 months.
• Fee increases. Ziegler’s Z-News for the week of September 7, 2026 reports average monthly fee increases for Independent Living falling from 6.2% in 2023 to 5.2% in 2024, 4.7% in 2025 and 4.1% in 2026, with 4.3% projected for 2027. These are fee increases to existing residents, not market rents, so they are not directly comparable with CBRE’s figures.
• Exit pricing. Underwriters are not leaning on cap rates falling further. JLL’s survey found that over half of respondents assume a terminal cap rate 50 bps above the going-in rate on a 10-year hold. CBRE found only 59% now expect cap rates to compress over the next 12 months, down from 84% six months earlier.

Occupancy is the one lever that could help. JLL puts primary-market occupancy at 89.9% and secondary markets at 90.0% in Q4 2025, so there is room to fill. But filling units adds revenue once. It does not change the annual race between rent growth and cost growth, which is the subject of the next section.

The cost side: only one scenario clears the bar

Sourced estimates put operating expense growth at 3.5% to 5.0% a year, so whether a buyer reaches 6.3% NOI growth depends on whether rents outrun that range.

Haven Senior Investments puts operating expense growth in senior living and Life Plan communities at a baseline of 3.5% to 5.0% annually, a meaningful deceleration from the spikes of recent years. Based on what I’m seeing in labor, utilities, insurance and food costs, I think the real figure is closer to 5%.

Labor is the biggest driver. ASHA’s 2024 State of Seniors Housing, as reported by Senior Housing News, found operators spend about 55% of operating expenses on labor-related costs. Underwriting looks light against that. In JLL’s survey, about two-thirds of respondents underwrite 3% inflation and a little under a quarter use 4%, at or below the low end of Haven’s range.

Operating leverage makes the gap matter. Welltower’s same-store NOI margin was 27.7% in Q1 2026 (as reported by MMCG Invest), so expenses are roughly 72% of revenue. That is a premium portfolio, so treat it as illustrative. At that margin, each point that expenses outgrow revenue cuts NOI by about 2.6%. Applied to the $50M example ($3.1M of NOI on about $11.2M of revenue and $8.1M of expenses), year-one NOI growth looks like this:

The scenarios are my calculations. They assume flat occupancy and that revenue growth equals rate growth. Occupancy gains could add revenue, which is the one real offset. But only the first row, with rents at CBRE’s forecast and costs at the midpoint of Haven’s range, clears the bar. If expenses grow 5%, revenue has to grow about 5.4% to deliver 6.3% NOI growth, which is above CBRE’s forecast.

Where this leads: the bet is on demand

Buyers are not paying for today’s income. They are paying for a belief that rents will keep outrunning costs.

The case for that belief is real. JLL says high-quality assets are trading below replacement cost, at an average of $182.8K per unit (2026 Seniors Housing & Care Investor Survey and Trends). CBRE, citing NIC MAP, reports only 19,839 units under construction in Q1 2026, 16 straight quarters of decline, against a need for more than 190,000 units by 2028. JLL projects the 80+ population will grow 36.6% over the next decade, against 5% for the total population.

Those numbers say how many people will be old. They do not say how many can pay. The math above needs rent growth of 5% or more, year after year, from residents who pay privately. NORC’s Forgotten Middle research (New Projections Anticipate a Slowdown in Household Growth and Housing Demand | Joint Center for Housing Studies), as summarized by MMCG Invest, finds that 75% of middle-income households aged 75 and older cannot afford private-pay assisted living without selling home equity, and 39% cannot afford it even after selling. https://rhislop3.com/a-population-peek-at-housing-demand/

The next post takes up that question: whether the demand the underwriting assumes is real, or phantom.
