Managing 10 Condos Is Not 10 Times the Work of Managing One

Estimated reading time: 8 minutes

In May 2026, Montreal-based Jesta Group announced plans to spend $500 million buying more than 1,000 newly built Toronto condos — converting unsold developer inventory into a managed rental portfolio. The move was widely covered as a signal that institutional investors see value in Toronto’s battered condo market at current prices.

Less discussed was the infrastructure required to make that bet work. Jesta is not buying 1,000 condos and managing them alone. They have capital allocation teams, asset management systems, leasing operations, maintenance networks and financial reporting infrastructure built specifically for this kind of portfolio. The investment thesis and the management infrastructure are inseparable. You cannot have one without the other.

The individual investor looking at the same market opportunity — a handful of newly completed condos available below replacement cost, rental demand that remains structurally intact, a window to build a meaningful income portfolio — is working with the same asset class and a fundamentally different operational reality.

This article is about that gap. Not to argue that individual investors shouldn’t pursue portfolio growth — many should, and many will do it successfully. But to map, as honestly as possible, what actually changes as a condo portfolio grows. Because the complexity curve is not linear, and the investors who get into trouble are almost never the ones who made a bad decision at unit one. They’re the ones who added unit seven without noticing that the job had already changed.

The self-management ceiling: there is no magic number

Managing one rental property yourself is entirely reasonable for most people. A single condo in Toronto requires finding and screening a tenant, executing a lease, collecting rent each month, responding to maintenance requests, coordinating repairs, conducting periodic inspections and handling the annual financial summary for tax purposes. For someone organised and attentive, this is a manageable part-time commitment.

Where it gets complicated is not a function of a specific unit count. It is a function of the person, their situation and the tenants they happen to have.

Consider two scenarios. An investor with a six-unit building and stable, considerate tenants who have lived there for years may find the management workload genuinely light — a maintenance call here, a renewal notice there. The same investor with a duplex whose two tenants are in open conflict over noise, shared garbage and a disputed utility split may find that two tenancies consume more time and emotional energy than they ever anticipated.

The number of units is not the variable. The nature of those tenancies is.

“It’s case by case. You could have a six-plex with great tenants that’s easier to manage than a duplex with two tenants who can’t stand each other. The number of units isn’t the thing — it’s the nature of those tenancies, and how much of your life you’re prepared to give to managing them.”

— Brian Reid-Moran, Operations Manager, LandLord Property & Rental Management

What does reliably increase with unit count is the probability that something will require your full attention at the exact moment something else does too.

One condo is easy — until it isn’t. Two condos are manageable — until both need something at the same time.

The more units you add, the more certain it becomes that you will face simultaneous demands: a vacancy to fill, a maintenance emergency to coordinate, a tenant dispute to navigate, a lease renewal to negotiate.

Not sequentially. At the same time.

“There’s no magic number. One condo is easy, until it’s not. The more units you add, the higher the probability that you’ll have to do something — and that something will arrive at the worst possible moment.”

— Trevor Valade, Vice President, LandLord Property & Rental Management

Two variables determine where an individual investor hits their ceiling.

Interpersonal capacity

The first is interpersonal — the capacity to manage conflict, to have difficult conversations with tenants and to hold a firm position on a lease clause without the exchange becoming adversarial.

Property management at any scale is a people business. The administrative load is real but learnable. The human dynamics are harder to systematise.

Administrative capacity

The second is administrative — the capacity to maintain accurate financial records, track multiple compliance timelines and respond to maintenance requests promptly across several properties at once.

For someone who is retired or has significant time available, this is a different constraint than for someone managing a portfolio alongside a full-time career and family commitments.

Neither variable is fixed. Both are worth assessing honestly before adding the next unit.

The investors who get into difficulty are rarely the ones who made a bad decision at unit one. They are the ones who added unit five or unit six without noticing that the nature of the job had already changed — that what had been a manageable part-time commitment had quietly become something that required more than they had to give it.

At that point, the work you are simultaneously carrying includes:

• Multiple active tenancies at different stages — some mid-lease, some approaching renewal, some in the process of turnover
• Multiple maintenance streams — different issues at different properties, with different vendors, at different stages of resolution
• Multiple financial reconciliations — statements across multiple buildings, multiple condo corporations and multiple expense profiles
• Multiple leasing cycles — units coming available at different times, requiring simultaneous marketing, showings, screening and lease execution
• Multiple compliance timelines — lease renewals, rent increase notices, inspection schedules and non-resident tax remittances if applicable

None of these streams coordinates with the others.

A maintenance emergency at one property does not pause the lease renewal conversation at another. Three units going vacant in the same month is not three times the work of one vacancy — it is three simultaneous leasing campaigns, three sets of showings, three screening processes and three move-in inspections, running in parallel.

What a professional management operation actually looks like

It is worth being specific about what professional property management infrastructure involves, because the comparison clarifies what a self-managing investor at scale is actually taking on.

A professional property manager handling a large portfolio is not one person doing everything.

Behind the account manager who is the owner’s point of contact, there is a leasing team managing listings, showings and tenant screening. A separate financial operations team handles rent collection, trust accounting, bill payments and financial reporting. A maintenance coordination function manages vendor relationships, work order dispatch and follow-up. A compliance function manages non-resident tax, lease administration and regulatory requirements.

The account manager, in this model, is the coordinator and the relationship — the person with the judgment to make decisions and the context to understand each property’s specific situation. The specialised functions behind them handle the volume and the process. Neither works without the other.

A self-managing investor at 15 to 20 units is, functionally, trying to be all of those roles simultaneously.

Not because they lack skill or organisation — but because the work genuinely requires specialisation at that scale, in the same way that a small business owner eventually needs to stop doing their own bookkeeping, payroll and legal work. Not because those tasks are beyond them individually, but because doing all of them well while also running the business is more than one person can sustain.

The concentrated portfolio: a specific set of problems

The bulk-buy model — buying multiple units in the same building — creates a different set of management challenges than a distributed portfolio of the same size.

Both are complex. The complexity is different in kind.

Correlated risk

In a distributed portfolio, vacancies are largely independent events. A unit going empty in one building has nothing to do with occupancy in another.

In a concentrated building, they can correlate.

A building that develops a noise problem, a management dispute, a pest issue or a difficult neighbour affects your exposure across every unit you own there simultaneously.

A distributed investor has a vacancy. A concentrated investor can have ten.

Self-competition

When you own multiple units in the same building, you are, at turnover, competing with yourself.

A two-bedroom on the 12th floor that you are trying to lease at $3,200 per month is directly compared by prospective tenants to the identical two-bedroom on the 8th floor that you listed for $3,050 last month and hasn’t leased yet.

Tenants in the building talk. Prospective tenants look at both listings. The pricing and timing of your own units affect each other in ways that a distributed portfolio does not create.

Condo corporation exposure

In a 200-unit building where you own 10 units, you are a 5 per cent stakeholder in everything the condo corporation decides.

A special assessment for a roof replacement or elevator repair — common in buildings that are 10 to 15 years old — hits you 10 times. A vote to increase monthly condo fees affects your operating costs across the entire concentrated position simultaneously.

A building with a poorly funded reserve or a contentious owners’ corporation is not one problem — it is a systemic exposure across your whole investment in that building.

The advantage case

Concentration is not without genuine advantages, and an honest account includes them.

A concentrated portfolio means one building to know deeply — one set of mechanical systems, one vendor relationship, one condo corporation to manage and one neighbourhood to understand.

At sufficient scale within a single building, there may be negotiating leverage with vendors and a degree of influence in building governance.

These are real advantages. They are also only advantages if the building itself is well chosen and well managed — which brings the analysis back to the quality of the management operation, not just the ownership structure.

The distributed portfolio: more coordination, less correlated risk

Owning 10 units across eight buildings in different Toronto neighbourhoods diversifies the risks above.

A problem in one building stays in one building. Vacancies do not correlate. Condo fee increases and special assessments affect one unit at a time. You are not competing with yourself on pricing.

What you are doing instead is managing eight different buildings, eight different condo corporations, eight different sets of building-specific knowledge, different vendor relationships for building-specific maintenance and different tenant profiles across multiple rental submarkets.

The coordination burden is genuinely higher. The risk profile is genuinely more resilient.

Whether that trade-off makes sense depends on the investor — their time, their systems, their tolerance for operational complexity and their assessment of building-specific versus portfolio-level risk.

The question is not whether to concentrate or distribute — it is whether your management infrastructure matches your ownership structure. An investor with the systems and team to manage concentrated risk well can build a highly efficient portfolio in a single building. An investor without those systems, managing alone, is most exposed precisely where concentration appears to offer efficiency.

What this means for investors watching the current market

Toronto’s current condo market — with record unsold inventory, motivated developers and an HST rebate window for new rental conversions — is a genuine opportunity for investors who can execute.

The case for building a condo rental portfolio in 2026, at prices that reflect the market’s current distress rather than its peak, is not unreasonable.

What is worth thinking through carefully, before the portfolio grows, is the management question.

Not as a reason not to invest — but as a variable in the return calculation that is as important as the acquisition price and the achievable rent.

A poorly managed unit in a strong market still underperforms a well-managed unit.

A vacancy that lasts four weeks longer than necessary because the leasing process was disorganised costs real money. A maintenance issue that escalates because it wasn’t addressed promptly costs more. A tenancy that ends badly because the early warning signs weren’t noticed costs the most of all.

The investors who will do best in this window are the ones who have thought about the management infrastructure before they need it — not after the fifth unit is empty at the same time.
