What C$600,000 in Northern BC rental houses can do over 20 years: if you stop buying at Year 10 and let the portfolio sit, and if you spend the cash flow instead of reinvesting it.
Then let it sit
The portfolios from the flywheel model, but after Year 10 nothing is bought or refinanced. Loans keep amortizing, rents and costs keep rising, values keep growing at 3.5%, and the cash flow banks at 4.5%. Then everything is sold at Year 20.
| Strategy | Y10 net worth | Y20 net worth | Multiple of C$600k | 20-yr IRR | Y20 LTV | Y20 DSCR | Y20 cash flow |
|---|---|---|---|---|---|---|---|
| Buy-and-hold | C$2.02M | C$4.69M | 7.8× | 10.8% | 20.3% | 2.05× | C$91k |
| Conservative flywheel (75%) | C$2.43M | C$7.36M | 12.3× | 13.4% | 34.2% | 1.73× | C$175k |
| Aggressive flywheel (80%) | C$2.68M | C$9.76M | 16.3× | 15.0% | 41.9% | 1.55× | C$232k |
| Ungoverned 80% | C$2.80M | C$11.54M | 19.2× | 15.9% | 43.2% | 1.50× | C$278k |
| Stock index fund (7%) | C$1.18M | C$2.32M | 3.9× | 7.0% | – | – | – |
| 60/40 balanced | C$0.93M | C$1.45M | 2.4× | 4.5% | – | – | – |
Net worth after 3.3% sale costs, before income and capital gains tax. Selling everything in one year would trigger a large tax bill, so most investors would sell gradually or hold for income instead.
The conservative flywheel’s C$0.4M lead over buy-and-hold at Year 10 becomes about C$2.7M by Year 20, with no new purchases. The larger portfolio simply compounds for longer.
By Year 20, LTV has fallen to 34–42% and coverage has risen to 1.55–1.73×. The conservative portfolio pays about C$175k a year before tax, close to twice buy-and-hold.
Even in the Severe case, the governed portfolios reach about C$1.5–1.7M by Year 20 (2.6–2.8×). That trails a 7% index fund (C$2.32M), which is shown without market drops.
Or take the income
The 20-year figures above assume surplus cash flow is reinvested. Many investors would rather live on it. Here the same portfolios pay out all cash flow above the reserve every year, and only refinance proceeds from paydown and appreciation buy new houses. Bought and refinanced through Year 10, then held to Year 20.
| Income version | Income Y1 | Income Y10 | Income Y20 | Paid out over 20 yrs | Doors | Y10 net worth | Y20 net worth |
|---|---|---|---|---|---|---|---|
| Buy-and-hold | C$31k | C$56k | C$91k | C$1.18M | 6 | C$1.50M | C$2.98M |
| Conservative flywheel (75%) | C$31k | C$60k | C$106k | C$1.29M | 8 | C$1.62M | C$3.55M |
| Aggressive flywheel (80%) | C$31k | C$66k | C$148k | C$1.57M | 14 | C$1.81M | C$5.05M |
Income is pre-tax cash flow paid to the owner. Net worth is after 3.3% sale costs and excludes the income already paid out. Reinvesting everything instead ends Year 20 at C$4.69M, C$7.36M and C$9.76M.
About C$31k in the first year on C$600,000, rising with rents and doors to C$56–66k by Year 10 and C$91–148k by Year 20, before tax.
With no cash flow reinvested, the aggressive version still grows from 6 doors to 14 on refinance proceeds alone, pays out C$1.57M over 20 years and ends at about C$5.05M. The conservative version adds only one house: its 75% gate leaves little to take out once cash flow is spent.
Reinvesting everything for the first 10 years leaves the flywheels about 1.5 times better off at Year 20, even after adding back the C$1.3–1.6M the income versions paid out. The real choice is income now or a bigger engine later, and many clients blend the two: reinvest until the portfolio reaches their “enough” number, then switch to income.
In the Severe case, payouts fall to near zero for most of Years 2–9 in every version, and the reserve carries the portfolio. Income starts again as rates and vacancies normalize.
Same houses, same rules

The income you want, when you want it, and the capital you have. I’ll run it through the same model and show you the trade-off between income now and a bigger portfolio later.
Method, limits and disclosure
An annual simulation with per-loan tracking, monthly compounding and pre-tax, nominal CAD figures, run for 20 years with no purchases or refinances after Year 10. Net worth is after 3.3% sale costs and before income and capital gains tax. Income is pre-tax cash flow above the reserve requirement. The stock-index (7%) and 60/40 (4.5%) benchmarks are net of fees, before tax, and shown without market drops. Surplus cash and reserve yields follow the FP Canada 2026 Projection Assumption Guidelines.
