Reverse Mortgage: Lump Sum or Monthly Advances?
Published July 2, 2026 · By YYZ Mortgage
The headline decision on a reverse mortgage is how much. The decision almost nobody spends enough time on is how — one cheque now, or a monthly deposit for years?
It sounds like a preference. It’s actually the single biggest lever on what the loan costs you, because of one rule: interest accrues only on money actually advanced.
The three ways to receive the money
- Single lump sum — everything on day one. Required at least in part when the loan must first pay off an existing mortgage or secured debt.
- Initial advance + ad-hoc draws — take what you need now, request more later (lender minimums apply, commonly $5,000–$10,000 per draw, ~$50 processing on some products).
- Scheduled advances — a fixed deposit monthly or quarterly, pension-style: HomeEquity Bank’s Income Advantage (setup fee $2,495) or Equitable Bank Flex scheduled advances. Amounts can typically be adjusted or paused.
Most real borrowers end up with a blend of 1 and 3. The mistake is defaulting to a full lump sum for money you won’t spend for years.
The math that should drive the choice
Illustrative example. You want $150,000 of support over the next decade, at 7% (compounded per Canadian convention). Two structures:
Option A — $150,000 lump sum today. The full amount compounds from day one. After 10 years the balance is roughly $298,000 — about $148,000 of interest.
Option B — $1,250/month scheduled advances. Same $150,000 of total principal, but the dollar you receive in year 9 only accrues interest for one year. After 10 years the balance is roughly $215,000 — about $65,000 of interest.
| Lump sum | Monthly advances | |
|---|---|---|
| Principal received | $150,000 | $150,000 |
| Interest after 10 yrs | ~$148,000 | ~$65,000 |
| Balance after 10 yrs | ~$298,000 | ~$215,000 |
Same money in your pocket; roughly $83,000 less against your estate. That’s not a rounding difference — it’s the whole argument for matching the draw schedule to the spending schedule. (Both figures are illustrative; your rate resets at each term and actual products differ. The full cost guide covers the rest of the fee picture.)
There’s a second, quieter benefit: money you haven’t drawn yet isn’t sitting in your chequing account tempting anyone — a real safeguard consideration that families managing a parent’s finances appreciate.
When each structure wins
Lump sum is right when the need is immediate and total:
- Paying off an existing mortgage — required at funding, and it ends a monthly payment.
- A major renovation, a grey-divorce buyout, clearing 20%-interest credit cards.
- Day-one money has to be day-one borrowing; no structure avoids that.
Scheduled advances are right when the need is monthly:
- Topping up retirement income — groceries-and-bills money, $800 or $2,000 a month.
- Funding in-home care with its inherently monthly cost profile.
- Any plan where the honest answer to “when will you spend it?” is “gradually.”
They also stack cleanly with government benefits: scheduled advances, like all reverse mortgage proceeds, don’t reduce OAS or GIS — unlike the RRIF withdrawals they often replace.
The blend — an initial advance for the immediate item plus modest scheduled advances after — is the most common well-designed outcome. What we push back on, every time, is the reflexive maximum lump sum “just to have it”: paying 7% compounding on money parked in a 2% savings account is a guaranteed loss with no upside.
Practical fine print
- Fees differ by structure: Income Advantage carries a $2,495 setup fee (vs $1,795 standard CHIP); Equitable’s setup is $995 across Flex products. Ad-hoc draws may carry small processing fees and minimums.
- Rates differ slightly between products and reset at term renewals — we compare the current sheets, with APRs, when we prepare your options.
- Flexibility is real but bounded: adjusting schedules and requesting extra draws works within your approved limit and product rules. Confirm the specifics before signing, not after.
Get the structure priced both ways
The right question isn’t “how much can I get?” — it’s “how much do I need, and when?” Bring the answer (even roughly) and we’ll show you the same plan priced as a lump sum, as scheduled advances, and blended — with ten-year projections for each, free.

Frequently asked questions
Can a reverse mortgage pay me monthly like a pension?
Yes. Scheduled-advance products — such as HomeEquity Bank's Income Advantage or Equitable Bank's Flex scheduled advances — deposit a set amount monthly or quarterly. Interest accrues only on money actually advanced, which makes this structure far cheaper over time than taking everything up front.
Which costs less: lump sum or monthly advances?
Monthly advances, dramatically, when the money is for ongoing spending. Drawing $1,250 a month for ten years costs roughly $65,000 in accumulated interest at 7%, versus about $148,000 if the same $150,000 had been taken as a day-one lump sum. The gap exists because most of the monthly money is borrowed years later.
When is a lump sum the right choice?
When the expense is immediate and total: paying off an existing mortgage (mandatory at setup), a major renovation, a spousal buyout, or clearing high-interest debt. Money you need on day one has to be borrowed on day one — the structure question only applies to money you'll spend later.
Can I combine a lump sum with monthly advances?
Yes, and many borrowers do: an initial advance clears the mortgage or funds the renovation, and scheduled advances top up monthly income afterward. You can also leave room to request ad-hoc advances later, subject to lender minimums.
Can I change the structure after starting?
Generally yes, within your approved limit — you can adjust or stop scheduled advances and request additional draws, subject to the lender's product rules and minimum advance amounts. Stopping advances also stops new interest from accruing on money you never took.
Do monthly advances affect OAS or GIS?
No. Like all reverse mortgage proceeds, scheduled advances are loan money, not income, so they don't reduce OAS, GIS or CPP — one reason retirees compare them against RRIF withdrawals for topping up monthly cash flow.
Figures shown are estimates only — not an offer of credit or a commitment to lend. The amount you may qualify for depends on the lender's assessment of your age(s), property type, location, appraised value and any existing liens. Reverse mortgage lenders require independent legal advice before funding. A reverse mortgage is not suitable for everyone; alternatives include refinancing, a home equity line of credit, or downsizing.
