What makes a rental property appraise well
A rental isn't valued like a home you live in. Here's what actually drives the number an appraiser lands on.

Homeowners often assume a rental property is valued the same way as any other house or condo: comparable sales, square footage, finishes. That's only part of the picture. A rental's value is also a function of how well it performs as a business, and that shows up in the appraisal.
Documentation drives the number
A property with a clean lease, a documented rent history, verified tenant payment records, and clear maintenance logs is straightforward to value with confidence. A property with informal arrangements, cash payments, or no paper trail forces a valuation professional to guess, and guesses tend to land on the conservative side.
Legal compliance affects marketability
A basement suite without proper fire separation, interconnected alarms, or legal egress isn't just a safety issue — it's a valuation issue. An unregistered or non-compliant secondary unit generally can't be counted as income-producing space in a formal appraisal, even if it's currently rented and generating cash flow.
- Legal, registered secondary suites add appraised value
- Unregistered suites are often excluded from the income calculation entirely
- Permits and inspection records should be kept with the property file
Real cash flow, not gross rent, is what counts
Gross rent tells only part of the story. Property tax, insurance, a vacancy allowance, and maintenance all get netted out before a valuation treats the income as reliable. A property that looks strong on rent alone but has thin real cash flow will be valued more cautiously than one with a wider margin.
Screening and tenancy history matter more than people expect
A stable, long-term tenant paying reliably is worth more to a valuation than a string of short tenancies with turnover costs and vacancy gaps. If you're preparing a property for a valuation, a summary of tenancy history over the past few years is worth putting together.
Getting an accurate number
If you're deciding whether to hold, refinance, or sell a rental, don't rely on a rough estimate based on what similar units listed for. Ask for a valuation that actually incorporates your rent roll, your expenses, and your legal compliance status — that's the number that will hold up when it matters.
