Investment Property in Moncton, Fredericton, and Saint John: A Side-by-Side Comparison

New Brunswick is not one investment market. It is three very different cities with three very different risk profiles, and the one you choose determines whether your duplex throws off reliable cash flow or bleeds money on deferred maintenance you did not budget for.

Most out-of-province investors land on New Brunswick because the entry prices make Ontario and BC look absurd. A cash-flowing duplex for the price of a GTA condo parking spot. No provincial speculation tax. No foreign buyer penalty. The macro case is compelling. But the city-level decision is where investors actually make or lose money.

Here is what the numbers look like as of the October 2025 CMHC data, and what those numbers actually mean for your returns.

The Numbers at a Glance

Moncton: The Balanced Play

Moncton is the city most out-of-province investors should start with. The Moncton CMA -- which includes the rapidly growing municipalities of Dieppe and Riverview -- is the commercial hub of the Maritimes, with demand driven by logistics companies, bilingual call centres, healthcare, the Universite de Moncton, and robust immigration through the Atlantic Immigration Program.

Why investors choose Moncton. The vacancy rate has eased from a stifling 1.2% in 2023 to a healthier 3.8% in 2025. That is still below the 5% threshold that would signal oversupply. Average two-bedroom rents at $1,452 are the highest of the three cities. The tenant pool is deep and diverse -- not dependent on a single employer or industry.

The sub-market picture matters. Moncton is not uniform. Central Moncton carries a 4.6% vacancy and lower rents ($1,348), reflecting older stock and higher turnover. West Moncton runs at 2.5% vacancy with $1,437 rents -- tighter, newer, and more suburban. Dieppe sits at 3.9% vacancy but requires bilingual property management (70%+ francophone population). Riverview is tight at 2.9%.

Where the yield sits. A typical Moncton duplex acquired for $250,000 with both units at the two-bedroom average of $1,452 generates gross monthly revenue of $2,904. At an 80% LTV with a 5.5% mortgage rate over 25 years, your monthly principal and interest payment is roughly $1,215. After property taxes (approximately $4,800 annually for a non-owner-occupied duplex at Moncton's combined rate), insurance ($2,400), and 10% property management ($3,485), the property should cash flow positively on a monthly basis -- though the margin is tight once you account for maintenance reserves.

The Moncton risk. New construction is catching up with demand. The easing from 1.2% to 3.8% vacancy in two years reflects substantial new apartment completions entering the market. If construction continues at the current pace and immigration slows, vacancy could push above 5%, putting downward pressure on rents. Municipal housing planners still report a structural shortage of affordable units in the $1,200 to $1,600 range, which supports mid-market investors, but premium units are facing stiffer competition.

Fredericton: The Stability Play

Fredericton is for investors who prioritize capital preservation and sleep-at-night reliability over maximum cash flow.

Why investors choose Fredericton. The provincial capital's economy runs on government employment, two universities (UNB and St. Thomas), and CFB Gagetown. These are non-cyclical demand drivers. Government workers do not get laid off during recessions. University enrollment is predictable. This makes Fredericton the most defensive rental market in New Brunswick.

The recovery from extreme scarcity. Fredericton's vacancy rate of 0.9% in 2024 was the lowest CMHC had ever recorded for the city since tracking began in 1990. The jump to 2.5% in 2025 reflects a wave of new residential construction that has added meaningful supply. But 2.5% is still tight by national standards, and affordable housing creation continues to lag behind the city's housing needs assessment targets.

Where the yield sits. Average two-bedroom rents at $1,431 are slightly below Moncton. Acquisition prices for duplexes are comparable. The yield math is similar to Moncton, but with one critical difference: tenant turnover is lower. Government tenants stay for years. Lower turnover means fewer placement fees, fewer vacancy months, and lower management costs over time. The total return, factoring in these savings, can match or exceed Moncton despite the slightly lower headline rent.

The student housing variable. Properties near the university command reliable September-to-April demand but face a summer vacancy gap. If your property targets students, you need to account for one to three months of vacancy annually unless your PM company aggressively markets to summer sublets or short-term renters. This seasonal gap is the hidden yield drag that makes Fredericton student housing look better on paper than it performs in practice.

The Fredericton risk. The market is small. Fredericton's entire CMA population is roughly 110,000, compared to Moncton's 175,000+. A single large employer departure -- unlikely with the government, but possible with a private-sector anchor -- would have outsized effects on rental demand. The smaller market also means fewer exit options when you eventually sell. Liquidity is lower than in Moncton.

Saint John: The High-Yield, High-Risk Play

Saint John is where the biggest numbers and the biggest disasters both live. It is the city that looks irresistible on a spreadsheet and punishing in practice.

Why investors choose Saint John. The entry prices are the lowest in the province. Multi-unit buildings can be found for under $200,000. Average two-bedroom rents at $1,290, while the lowest of the three cities, still generate gross yields that dwarf anything in Ontario or BC. The vacancy rate tightened unexpectedly to 2.1% in 2025 -- down from 3.9% the prior year -- driven by a lag in construction completions and ongoing demand from affordability migration and household formation.

The maintenance reality. Canada's oldest incorporated city has a housing stock to match. Victorian and Edwardian buildings with stone foundations, knob-and-tube wiring remnants, galvanized plumbing, and aging heating oil infrastructure. Nearly 40% of residential oil spills reported to the New Brunswick Department of Environment come from domestic oil tanks. A leaking buried tank can cost $15,000 or more in remediation.

Out-of-province investors are regularly drawn to Saint John by sticker prices, buy based on gross yield calculations, and then discover that the capital expenditure required to bring the building to rentable condition -- or to simply maintain it -- consumes the entire cash flow advantage.

The North End trap. The North End offers the lowest prices in the city, but CMHC specifically notes that the 3.7% vacancy rate there is skewed by units that are "functionally uninhabitable due to extreme disrepair." Buying a North End building on yield alone, without inspecting the property and budgeting $30,000 to $50,000 in immediate capital repairs, is the most common way out-of-province investors destroy their returns in New Brunswick.

The tax headwind. The provincial assessment freeze for 2026 excludes new buyers and out-of-province investors. This means your property tax bill may be significantly higher than what the previous owner paid on the same building. Combined with New Brunswick's "double tax" on non-owner-occupied properties (both municipal and provincial rates), the holding cost burden in Saint John can erode the yield advantage that drew you to the city in the first place.

The Saint John risk. The economic base is narrower than Moncton's. Heavy dependence on the Irving industrial complex means that any structural change to that employer affects the entire rental market. The older housing stock means higher ongoing capital expenditure. And the smaller, more volatile tenant pool -- particularly in certain neighborhoods -- generates higher arrears risk and more frequent tribunal actions.

Which City Fits Your Strategy?

Choose Moncton if you want the most balanced risk-return profile, the deepest tenant pool, and the most liquid exit. It is the default for first-time New Brunswick investors and out-of-province buyers managing remotely.

Choose Fredericton if you prioritize stability over maximum yield, want the lowest-turnover tenant base, and are comfortable with a smaller, less liquid market. Ideal for investors who want predictable, boring, reliable cash flow.

Choose Saint John if you have renovation experience, a higher risk tolerance, access to reliable local contractors, and the capital reserves to absorb major maintenance surprises. Saint John rewards sophisticated operators who can reposition distressed assets. It punishes passive investors who buy on yield and neglect maintenance.

Consider a multi-city portfolio if you are deploying enough capital to diversify. Owning units in both Moncton and Fredericton gives you economic diversification (commercial hub plus government capital) without the elevated maintenance risk of Saint John.

What the Numbers Do Not Tell You

Vacancy rates and average rents are starting points, not conclusions. They do not capture the double property tax on non-owner-occupied properties, the 3% annual rent cap that limits your revenue growth, the six-month notice period for rent increases, or the capital expenditure risk in older buildings.

The New Brunswick Investment Property Guide includes city-specific cash flow models for all three markets, property tax calculators that account for the non-owner-occupied premium, and a due diligence checklist covering the environmental, structural, and legal risks unique to each city -- so you can compare investments based on what you will actually earn, not what the listing agent's rent estimate implies.
