Most landlords in Central Nova Scotia know that underpricing their rental units costs money. What many do not realise is how dramatically the 5% rent cap amplifies that cost over time. In an unregulated market, underpricing is a correctable mistake — you adjust to market rate at the next renewal. Under the rent cap, underpricing is a compounding problem that grows every year, and the cumulative cost is far larger than most landlords expect.
Here is the math, using real Halifax market data.
The Compounding Effect: A Worked Example
Take a Halifax two-bedroom unit that should rent for $2,200 per month at current market rate. The landlord sets the initial rent at $2,000 — a $200 underprice based on what the last tenant paid rather than a proper market analysis.
Under the 5% rent cap, here is what happens over five years, assuming the broader market continues growing at the conservative 4.0% annual rate Halifax has averaged:
Year 1
- Market rate: $2,200/month
- Your rent: $2,000/month
- Monthly gap: $200
- Annual revenue loss: $2,400
Year 2
- Market rate rises to: ~$2,288 (4% growth)
- Your rent after maximum 5% increase: $2,100
- Monthly gap: $188
- Annual revenue loss: $2,256
- Cumulative loss: $4,656
Year 3
- Market rate: ~$2,380
- Your rent after 5% increase: $2,205
- Monthly gap: $175
- Annual revenue loss: $2,100
- Cumulative loss: $6,756
Year 4
- Market rate: ~$2,475
- Your rent: $2,315
- Monthly gap: $160
- Annual revenue loss: $1,920
- Cumulative loss: $8,676
Year 5
- Market rate: ~$2,574
- Your rent: $2,431
- Monthly gap: $143
- Annual revenue loss: $1,716
- Cumulative loss: $10,392
Even in this scenario, where you apply the full 5% increase every year and the market grows at a moderate pace, the gap narrows slowly. After five years, you are still $143 per month below market rate, and you have lost over $10,000 in cumulative revenue on a single unit.
If the market grows faster than 4% (Bedford and Sackville saw 21.6% growth last year), the gap widens instead of narrowing, and cumulative losses exceed $12,000 to $15,000 over five years.
Scale the Problem: Multi-Unit Impact
The single-unit analysis is concerning. The multi-unit analysis is alarming.
Our 8-plex case study found six of eight units priced $150 to $300 below market. The average underprice was roughly $200 per unit. Across eight units, that represented:
- Monthly revenue loss: $1,600
- Annual revenue loss: $19,200
- Five-year projected loss: Over $80,000 in cumulative foregone revenue
After data-driven repricing using our AI-powered comparative market analysis, monthly rent went from $9,600 to $13,300. NOI grew from $78,000 to $137,000 annually. The property value increased from $1.38M to $2.6M — an 88% increase driven primarily by optimised rental income.
For multi-unit property owners, the cost of underpricing is not a rounding error. It is a six-figure impact on property value and cash flow.
Why Landlords Underprice (And Why It Feels Rational)
Underpricing is rarely a deliberate choice. It happens because of common, understandable behaviours:
Anchoring to the Previous Tenant’s Rent
The most common pricing method among self-managing landlords is adding a small increment to what the last tenant paid. If the last tenant was paying $1,800, the new listing goes up at $1,850 or $1,900. But if the market has moved to $2,100 since that lease was signed, the anchor is wrong by $200 or more.
Fear of Vacancy
Many landlords set rent below market because they want to fill the unit quickly and avoid vacancy. The logic is understandable, but the economics do not support it. A one-month vacancy at $2,200 costs $2,200. Underpricing by $200 per month costs $2,400 in year one alone, and the cost compounds. The vacancy is cheaper than the underprice.
Lack of Comparable Data
Setting rent accurately requires current data on what comparable units in your specific neighbourhood are achieving, not asking for, but actually renting for. Most landlords do not have access to this data in a systematic way. A comparative market analysis using 40+ data points provides the specificity that Kijiji browsing cannot match.
Emotional Attachment to “Good” Tenants
Some landlords keep rents low because they have a reliable tenant and do not want to risk the relationship. Tenant retention is valuable, but under the rent cap, you can still increase rent by 5% annually for existing tenants. Not applying the full allowable increase when your rent is already below market compounds the cost.
The Property Value Connection
Underpriced rent does not just reduce your cash flow. It directly reduces your property value. Investment properties are valued based on their income, typically using a capitalisation rate applied to net operating income.
Using a standard 6.5% cap rate:
- Property with NOI of $78,000: Valued at approximately $1.2M
- Property with NOI of $137,000: Valued at approximately $2.1M
That is the difference from the 8-plex case study. The property did not physically change. The building did not get taller. The location did not improve. What changed was that rental income was optimised to market rate, and NOI increased accordingly. The property value followed.
If you are considering selling your property, or if you want to refinance based on appraised value, underpriced rents are suppressing both your income and your equity.
The Solution: Data-Driven Initial Pricing
The fix is straightforward. Before setting rent on any new tenancy, get a data-driven market analysis that accounts for your specific unit, neighbourhood, condition, and current market dynamics.
At Kirin, our AI-powered CMA evaluates over 40 data points for every unit. The result is a specific rent recommendation backed by the same institutional-grade analytics that large REITs use for their portfolios. It takes the guesswork out of the most consequential financial decision you make as a landlord.
Under the rent cap, a CMA is not a luxury. It is the minimum standard for responsible rent-setting. Every dollar you leave on the table at lease signing follows you for the life of the tenancy.
What You Should Do
If you have units with rents set more than 12 months ago, or if you have a tenancy turning over in 2026, a comparative market analysis will show you exactly where you stand. Kirin offers a free CMA for Nova Scotia property owners. No obligation. No cost. Just data.
