Aging in Place vs Assisted Living: The $66,472 NPV Gap When September 2026's Flat Mortgage Rates Meet $0.10 Wage Growth
The question nobody answers with a spreadsheet
"Should Mom stay in her house or move to assisted living?" gets answered with feelings 95% of the time — "she doesn't want to leave," "we can't watch her fall again," "assisted living feels safer." Feelings matter. But underneath the feelings is a math problem, and this week's economic data changes the math more than most families realize.
On September 18, 2026, NerdWallet reported mortgage rates held flat for the week as bond markets digested Fed news — meaning if you're financing home modifications with a HELOC, your borrowing cost isn't moving in either direction right now. Meanwhile, the Bureau of Labor Statistics' latest release shows CPI up 0.4% for the month, unemployment steady at 4.1%, and average hourly earnings up just $0.10. That last number matters more than it sounds: slow wage growth for home health aides means in-home care costs may climb more gently over the next few years than facility costs, which carry insurance, real estate, and staffing-agency overhead layered on top of wages.
Here's a full worked example showing how that plays out — and why your numbers, not this example, are what should drive your decision.
The example household
Meet a hypothetical case we'll call the Thompson scenario: a 78-year-old widow, home worth $380,000 and paid off, currently needing help with 2 ADLs (activities of daily living — bathing and mobility). She's not in crisis, but her family is trying to decide now, before a fall forces the decision.
Aging in place costs (Year 1):
- Home modifications (grab bars, walk-in shower, stairlift, entry ramp): $28,500, financed via HELOC at today's flat rate
- In-home care, 25 hours/week at $33/hour (current market rate for home health aides): $42,900/year
- Year 1 total: $71,400
Assisted living (Year 1): median $5,900/month = $70,800/year
Nursing home, semi-private (Year 1): median $9,733/month = $116,796/year
Nearly a wash in year one between aging in place and assisted living. This is exactly why so many families stall — the sticker prices look close enough that the decision defaults to emotion. The gap only reveals itself once you project the ADL decline curve forward.
Where the ADL decline curve changes everything
This example household is losing roughly one additional ADL every 12-18 months — a fairly typical escalation pace discussed in the aging-in-place vs assisted living decision framework built around 3 ADL losses and 32 care hours per week. As ADLs decline, in-home care hours climb (in this example, roughly 4 hours/week per year), and facility care adds "level of care" surcharges — typically $125-$175/month per ADL loss beyond the baseline.
Running that forward five years, with home health aide wages growing modestly (~1.5%/year, consistent with the BLS's $0.10 hourly earnings print) versus facility costs growing near 5%/year (driven by insurance, staffing contracts, and the CPI pressure BLS flagged this month):
| Year | Aging in Place | Assisted Living | Nursing Home |
|---|---|---|---|
| 1 | $71,400 | $70,800 | $116,796 |
| 2 | $50,518 | $74,340 | $122,636 |
| 3 | $58,344 | $79,857 | $128,768 |
| 4 | $66,363 | $85,560 | $135,206 |
| 5 | $74,647 | $91,458 | $141,966 |
| 5-yr nominal total | $321,272 | $402,015 | $645,372 |
Discounted at 6% (a reasonable proxy for the cost of HELOC capital and opportunity cost combined) to get present value:
| Option | 5-Year NPV |
|---|---|
| Aging in place | $269,657 |
| Assisted living | $336,129 |
| Nursing home | $540,683 |
That's a $66,472 NPV gap favoring aging in place over assisted living, and a $271,026 gap versus nursing home care, for this specific household over five years. This is the kind of analysis Dorevanti runs for you — so you don't have to build the spreadsheet yourself, adjust the discount rate, or re-run it every time a new wage or rate print comes out.
Why "free money" for the home modification isn't free
NerdWallet's piece on homebuying assistance programs — "Locked Out: Should You Take 'Free Money' to Buy a Home?" — makes a point that applies directly here, even though it's about mortgages, not care: assistance that lowers your upfront cost often comes with strings — resale restrictions, forgivable-loan clawback periods, income caps that disqualify you later. The same logic applies to financing the $28,500 in home modifications in our example.
A HELOC at today's flat rate is straightforward debt you control. A reverse mortgage covers the modification cost without monthly payments but reduces the equity your estate — or your Medicaid spend-down calculation — can draw on later. A state or nonprofit home-modification grant might be genuinely free, but often comes with income limits or a requirement that you stay in the home for a set number of years. None of these are wrong choices. But treating the $28,500 as "just a cost" ignores that how you finance it changes your effective NPV by thousands of dollars, and changes your Medicaid eligibility timeline if a spend-down becomes necessary later.
The Medicaid spend-down wrinkle
If the ADL decline accelerates faster than this example — say, three ADL losses within 24 months instead of 60 — countable assets get depleted faster, and Medicaid eligibility for nursing home coverage moves closer. Home equity above your state's exemption limit counts against you during the 60-month look-back period, which is exactly why the financing choice above matters: a reverse mortgage draws equity down (helping spend-down math), while a HELOC preserves equity but adds debt that offsets it differently in an asset test. If your household is asset-light enough that Medicaid nursing home coverage is realistically 3-5 years out, the "aging in place wins" conclusion above can flip — nursing home NPV effectively drops once Medicaid starts picking up the bill, something the full crossover analysis across all four care levels walks through in more detail.
VA Aid & Attendance can close — or erase — the gap
If either spouse is a wartime veteran, VA Aid & Attendance benefits can meaningfully offset either side of this comparison. Suppose this example household qualifies for roughly $2,795/month in combined benefit (a plausible figure for a veteran/surviving spouse pair meeting the eligibility criteria) — that's $33,540/year, or roughly $142,000 in 5-year NPV terms at the same 6% discount rate. Stack that against either the aging-in-place or the assisted-living side and the $66,472 gap either nearly disappears or nearly doubles, depending on which option the benefit applies to and how your state treats it. This is precisely the kind of benefit-stacking calculation the VA Aid & Attendance stacking analysis covers in depth — and it's not optional math if a veteran is in the picture, because it can be the single largest variable in the whole comparison.
Life expectancy: the variable everyone skips
Every number above assumes a 5-year horizon. If this individual has a life expectancy closer to 8-10 years (reasonable for a 78-year-old woman with moderate ADL impairment, per standard actuarial tables), the aging-in-place advantage compounds — home modifications are a sunk cost that doesn't repeat, while facility costs keep escalating every year of the extended horizon. Conversely, if life expectancy is closer to 2-3 years, the $28,500 modification cost barely gets amortized before the comparison becomes moot. You can model this for your specific situation at Dorevanti, adjusting the time horizon, discount rate, and ADL decline pace independently rather than relying on a single fixed projection.
What actually determines your answer
None of the numbers above are universal. Your answer depends on:
- Your home's modification cost — a single-story ranch needs far less than a two-story colonial
- Local in-home aide wages, which vary $8-10/hour by region even with flat national wage growth
- Your actual ADL decline pace, which can be steady, sudden (post-stroke), or plateaued for years
- Whether VA benefits apply, and how much
- Your realistic life expectancy, adjusted for existing conditions, not just population averages
- How you finance the up-front cost, and what that does to your Medicaid spend-down clock
The September 2026 data — flat mortgage rates, 0.4% CPI, $0.10 wage growth, 4.1% unemployment — sets the backdrop everyone's calculation runs against right now. But the backdrop isn't the answer. Your household's specific numbers are. If you're staring at this decision for a parent or spouse, run your own version of this NPV comparison at Dorevanti before the decision gets made for you by a fall, a hospitalization, or a waitlist deadline.
