Sarah Chen was stuck. She knew it, her husband David knew it, and her bank had just confirmed it.
At 34 years old, Sarah was a registered nurse working full-time at a hospital in London, Ontario. She and David had bought their first rental property in 2022 — a three-bedroom semi-detached in a working-class neighborhood for $285,000. Six months later, they picked up a second one down the street for $310,000. Both were cash-flowing. Both were performing exactly as planned.
Then renewal time came around on their first mortgage. Sarah called her bank to discuss next steps, maybe pull some equity, maybe start planning property number three.
The banker told her she was done. Maxed out. Her debt service ratios were too high with two investment properties, and the bank wouldn’t approve another mortgage. She could renew what she had, but growing the portfolio wasn’t happening through them.
Sarah was 34, she had two rentals netting her $650 a month in combined cash flow, and according to her bank, this was as far as she could go.
That’s when she found LendCity.
Where Sarah Started: 2 Properties and a Ceiling
Let’s look at where Sarah actually stood when she first reached out to us in early 2023.
Property 1: 3-bedroom semi-detached, purchased for $285,000 in March 2022. Mortgage balance of $224,000 at 4.79%. Renting for $1,850/month. Positive cash flow of $280/month after all expenses.
Property 2: 3-bedroom semi-detached, purchased for $310,000 in September 2022. Mortgage balance of $248,000 at 5.14%. Renting for $1,950/month. Positive cash flow of $370/month after all expenses.
Combined portfolio value: roughly $650,000. Combined equity of about $178,000. Sarah’s T4 nursing income was $82,000 per year. David was earning $71,000 as a project coordinator.
On paper, she looked like a solid borrower. Combined household income of $153,000, good credit scores (both above 740), responsible debt levels, and two performing rentals. But her bank was only looking at one number: the ratio between her debt obligations and her income. And with the mortgage stress test pushing qualification rates above the contract rate, the math didn’t work for them.
The thing is, that math was wrong. Not wrong in the sense that the bank made an error — wrong in the sense that there were other ways to look at it.
The First Call with LendCity
When Sarah booked her first strategy call with us, she came in expecting to hear the same thing her bank told her. She figured a broker might find her a slightly better rate on renewal but wouldn’t be able to help her grow.
She was wrong about that.
The first thing we did was a full borrowing capacity analysis — not just what her current bank saw, but what her file looked like across the entire lending landscape. Different lenders calculate rental income offset differently. Some use 50% of rental income to offset your debts. Others use up to 80%. Some don’t cap it at all if the numbers are strong enough.
When we ran Sarah’s numbers through lenders that used more favorable rental income calculations, her debt service ratios told a completely different story. She wasn’t maxed out at all. She had room for at least two more conventional mortgages — possibly three — before she’d need to move to alternative lending.
We also identified something Sarah hadn’t considered: her existing properties had appreciated enough in the ten months since purchase that she was sitting on more equity than she realized. London’s rental market had been climbing, and her renovated semis were now worth roughly $320,000 and $345,000 respectively. That untapped equity was fuel for the next phase.
We mapped out a three-year plan. Conservative targets. Multiple financing paths depending on how the market moved. And we gave her homework: start looking for properties with value-add potential.
Properties 3-5: The BRRRR Phase
Sarah spent two months learning everything she could about the BRRRR method before pulling the trigger. David took a renovation course. They connected with a contractor who specialized in investor-grade renovations — functional upgrades that maximize appraisal value without overspending.
Then they started buying.
Property 3 — The First BRRRR (May 2023)
A two-bedroom bungalow in St. Thomas, listed at $215,000. It had been a long-term rental with deferred maintenance — original kitchen from the 1970s, worn carpeting, outdated bathroom, but solid bones. No structural issues. Roof was five years old.
Sarah negotiated a purchase price of $199,000.
Renovation budget: $38,000. They did a full kitchen and bathroom update, new LVP flooring throughout, fresh paint, new light fixtures, and addressed some electrical upgrades. Timeline was eight weeks.
After renovation, they listed it for rent at $1,750/month — $300 above comparable unrenovated units in the area. They had a tenant signed within two weeks.
Six months later, the property appraised at $295,000. They refinanced at 80% LTV through a lender we connected them with, pulling out $236,000. Their total investment had been roughly $237,000 (purchase price plus renovation). They got virtually all of it back.
Net monthly cash flow after the refinance: $190/month. Not spectacular on its own, but the point wasn’t the cash flow from one property. The point was getting the capital back to do it again.
Property 4 — Scaling the Formula (September 2023)
Armed with recycled capital, Sarah found a similar deal in Woodstock — a three-bedroom townhouse listed at $249,000, purchased for $232,000. Renovation cost: $41,000. Appraised value after: $335,000. She refinanced and pulled out $268,000 against total costs of $273,000. Left $5,000 in the deal.
Cash flow: $310/month.
Property 5 — The Pattern Holds (January 2024)
A duplex in Stratford for $289,000 (listed at $319,000 — the seller was relocating and motivated). Renovation: $52,000 across both units. Post-renovation appraisal: $415,000. Refinanced at 80% LTV for $332,000 against total costs of $341,000. Left $9,000 in the deal.
Combined cash flow from both units: $580/month.
In nine months, Sarah went from two properties to five. Her cash flow jumped from $650/month to over $1,700/month. And she’d only left about $14,000 of capital permanently deployed across three new acquisitions.
But then she hit the next wall.
The Wall at Property 5: When Conventional Lenders Cut You Off
Here’s something most investors don’t know until they run into it: most A lenders (big banks and monoline lenders) have internal policies that cap how many residential mortgages they’ll give to a single borrower. The common limit is four to five financed properties. Some go to six. A few stretch to ten. But at some point, the answer becomes no regardless of how strong your file is.
Sarah hit that wall at property five. Her credit was still excellent. Her ratios still worked. Her properties were all performing beautifully. But lenders were declining her applications purely because she had too many financed properties.
This is the moment where a lot of investors get stuck for years, or permanently. They assume the answer is “wait until you pay some off.” That can mean a decade of sitting on the sidelines.
We took a different approach. We moved Sarah to a portfolio lender — a financial institution that holds loans on its own books rather than selling them to CMHC or other insurers. Portfolio lenders have more flexibility in their underwriting. They look at the whole picture: your track record, the performance of your existing properties, the strength of the new deal. They care less about rigid ratio calculations and more about whether the deal makes business sense.
The trade-off is rates. Portfolio lenders typically charge 50-100 basis points more than A lenders. Sarah’s new rate was 6.24% instead of the 5.5% she might have gotten at a bank. But 6.24% on a property that cash flows is infinitely better than 0% on a property you can’t buy.
The Big Move: A 6-Unit Apartment Building with CMHC MLI
Everything up to this point had been single-family or small residential. But when Sarah told us she wanted to accelerate, we suggested she look at something bigger.
In June 2024, a 6-unit apartment building came on the market in Chatham — a small city about an hour southwest of London with strong rental demand and relatively affordable prices. The building had six one-bedroom units, all occupied, in reasonable condition. The seller was retiring and wanted a clean exit.
Asking price: $685,000. Sarah negotiated to $650,000.
This is where things got interesting from a financing perspective. For properties with five or more units, you move into commercial lending territory. And commercial lending opens up tools that don’t exist on the residential side — including CMHC MLI Select.
CMHC MLI Select is an insurance program for multi-unit residential properties. When a property qualifies, lenders can offer dramatically better terms than conventional commercial financing. We’re talking 85% loan-to-value (meaning Sarah only needed 15% down instead of 25-35%), amortization periods up to 40 years (instead of the standard 25), and interest rates that are lower than uninsured commercial loans because the lender’s risk is backed by CMHC.
Sarah’s 6-unit building qualified. Here’s what her financing looked like:
- Purchase price: $650,000
- Down payment (15%): $97,500
- CMHC-insured mortgage: $552,500
- Amortization: 40 years
- Interest rate: 4.89% (significantly below the uninsured commercial rate at the time)
- Monthly mortgage payment: $2,410
The six units were renting for a combined $6,300/month. After mortgage, property taxes, insurance, maintenance reserve, and property management (Sarah hired a manager for this building), she was netting $1,290/month in cash flow.
Run the CMHC MLI max loan calculator on a deal like that and you’ll see why experienced investors love this program. The 40-year amortization alone drops the monthly payment significantly compared to a 25-year amortization, dramatically improving cash flow on day one.
This single acquisition added six units to Sarah’s portfolio and generated more cash flow than her first three properties combined. That’s the power of multifamily.
Properties 7-12: Portfolio Lending and Creative Structuring
With the apartment building performing well and cash flow increasing monthly, Sarah had momentum. Over the next year, she added six more properties using a mix of financing strategies — because at this scale, no single lender or product handles everything. This is exactly what we outlined in our guide to scaling from 5 to 20 properties.
Property 7 (September 2024): A triplex in Windsor, financed through the same portfolio lender. Purchase price $420,000, 20% down. Cash flow: $640/month across three units.
Property 8 (November 2024): Another BRRRR deal — a detached home in Tillsonburg purchased for $225,000, renovated for $35,000, appraised at $320,000. Financed through a B lender at 6.89%. Cash flow: $220/month. The plan was to refinance into better terms after 12 months of seasoning.
Property 9 (January 2025): A duplex in Sarnia. This one required a private bridge loan to close quickly because the seller accepted Sarah’s offer on a tight timeline and her portfolio lender couldn’t move fast enough. We arranged a 12-month private mortgage at 9.5%, which she converted to a portfolio lender term mortgage three months later at 6.35%. Cash flow after conversion: $410/month.
Properties 10-11 (April 2025): Two side-by-side duplexes in Chatham purchased together from the same seller for a combined $590,000. Financed as a single commercial deal through a credit union. Combined cash flow: $860/month across four units.
Property 12 (August 2025): A single-family home in St. Thomas — a return to where she started with BRRRR. Purchased for $215,000, renovated for $28,000, appraised at $305,000. Refinanced through a B lender. Cash flow: $240/month.
Notice the mix. A lender, B lender, portfolio lender, credit union, private bridge loan, CMHC-insured commercial. Every property had a different financing path because every property presented different requirements. That’s why having a broker who understands the full spectrum of lending options matters more and more as you scale.
Sarah’s Portfolio Today: The Numbers
Here’s a snapshot of Sarah’s portfolio at the three-year mark:
| # | Property | Type | Purchase Price | Current Value | Monthly Cash Flow | Mortgage Type |
|---|---|---|---|---|---|---|
| 1 | London semi | Single family | $285,000 | $340,000 | $280 | A lender |
| 2 | London semi | Single family | $310,000 | $365,000 | $370 | A lender |
| 3 | St. Thomas bungalow | Single family | $199,000 | $305,000 | $190 | A lender (refi) |
| 4 | Woodstock townhouse | Single family | $232,000 | $345,000 | $310 | A lender (refi) |
| 5 | Stratford duplex | Duplex | $289,000 | $430,000 | $580 | Portfolio lender |
| 6 | Chatham 6-plex | Apartment (6 units) | $650,000 | $780,000 | $1,290 | CMHC MLI |
| 7 | Windsor triplex | Triplex | $420,000 | $465,000 | $640 | Portfolio lender |
| 8 | Tillsonburg detached | Single family | $225,000 | $330,000 | $220 | B lender |
| 9 | Sarnia duplex | Duplex | $310,000 | $360,000 | $410 | Portfolio lender |
| 10-11 | Chatham duplexes (x2) | Duplex (x2) | $590,000 | $650,000 | $860 | Credit union |
| 12 | St. Thomas detached | Single family | $215,000 | $310,000 | $240 | B lender |
Totals:
- Properties: 12 (20 total doors)
- Total acquisition cost: $3,725,000
- Current portfolio value: approximately $3,800,000 (accounting for equity built through BRRRR and appreciation)
- Total monthly cash flow: $5,390
- Annual cash flow: $64,680
- Equity position: approximately $1,200,000
Three years earlier, Sarah’s bank told her she was maxed out at two properties. Today she has twenty doors generating over $5,000 per month in cash flow, and over a million dollars in equity. Her nursing job is still her primary income, but her real estate portfolio now generates more annually than many people earn at their full-time job.
What You Can Learn from Sarah’s Journey
Sarah’s path isn’t unique. The strategies she used are available to anyone willing to learn them and execute consistently. Here are the takeaways that matter:
Your bank doesn’t define your borrowing capacity. Sarah’s bank said she was done at two properties. She wasn’t. Different lenders use different qualification methods, and a mortgage broker who specializes in investors will find paths your bank doesn’t even know exist.
BRRRR works, but it requires discipline. Sarah’s first three BRRRR deals recovered nearly all her invested capital. That only happened because she bought right, renovated smart, and didn’t overspend. The strategy falls apart when you pay too much or renovate too aggressively.
You will need to change lenders as you scale. A lenders for the first few properties, portfolio lenders when you hit the conventional wall, B lenders for speed or flexibility, CMHC MLI for multifamily, private financing for bridge situations. Each tool serves a purpose at a specific stage.
Multifamily accelerates everything. Sarah’s single 6-unit building generates more cash flow than her first five properties combined. If you can qualify for multifamily mortgage financing, it changes the math dramatically.
You don’t need to quit your job. Sarah is still a full-time nurse. Her real estate portfolio is managed through a combination of self-management (for local properties) and a property manager (for the 6-plex and out-of-town properties). Building a portfolio doesn’t require you to become a full-time investor — it requires systems and the right team.
Start with a plan, then adapt. The three-year plan we built with Sarah in that first call wasn’t followed exactly. Markets shifted, opportunities appeared in unexpected places, and timelines moved. But having a framework meant every decision was made in context, not in isolation.
Your Portfolio Could Look Like This
Sarah’s story isn’t extraordinary because of what she did. It’s extraordinary because of what she almost didn’t do. If she’d listened to her bank and accepted that two properties was her limit, she’d still be collecting $650 a month in cash flow and wondering what could have been.
The difference between investors who stay stuck at two or three properties and investors who scale to ten, twenty, or more almost always comes down to one thing: financing strategy. The properties are out there. The markets are accessible. The limiting factor is almost always how you structure the money.
That’s what we do at LendCity. We help investors see paths their banks won’t show them, connect them with lenders who understand portfolio growth, and build financing strategies that evolve as their portfolios expand.
If you’re sitting where Sarah was three years ago — a few properties, solid fundamentals, and a bank that tells you no — it might be time for a different conversation.
