Commercial Appraisal Preparation Checklist for Ontario Property Owners

A commercial appraisal in Ontario runs faster and prices tighter when the property owner arrives prepared. This is the preparation checklist we hand to owners before an engagement letter goes out: 14 actionable items in three phases - before the engagement letter, before the site visit, and during and after. Following it cuts turnaround and fee variance because the AACI signatory spends time on valuation reasoning, not chasing missing inputs.

Key takeaways

The largest preventable cause of slow Ontario commercial appraisals is missing or partial inputs at kickoff. The fix is preparation, not pressure.
Authorized use and authorized client are CUSPAP 2026 terms that drive report depth and reliance. Get them right in writing before the engagement letter is signed (CUSPAP 2026 s. 7.5.3; AIC, 2026).
Federally-regulated lenders and Ontario credit unions require an AACI-designated, lender-approved appraiser - confirm your lender's panel before paying for a report (RBC Royal Bank, 2026; FSRA, 2024).
Three deal-breakers surface late if you do not flag them upfront: environmental issues, leasehold complications, and partial-interest valuations.

Before the engagement letter

Four items belong in the discovery conversation. They define the assignment and decide whether your lender, court, or regulator will accept the finished report.

1. Clarify the authorized use and authorized client - in writing

CUSPAP 2026 uses authorized use for the purpose the report serves and authorized client for who may rely on it - the appraiser, not the engaging party, controls reliance (CUSPAP 2026 s. 7.5.3; AIC, 2026). Why it matters: authorized use drives which approaches are required, how the report is structured, and what post-delivery duties the appraiser carries. Completeness looks like a single written sentence the appraiser can copy into the engagement letter.

2. Identify the operative deadline

Lender renewal, court service date, IFRS quarter-end, insurance renewal, estate-filing window - whichever date governs your file. Why it matters: turnaround pressure is a primary driver of commercial appraisal fees in Ontario; the earlier the appraiser knows, the less likely a rush premium is necessary. For Ontario civil litigation, Rule 53.03 requires expert reports served 90 days before trial. Completeness looks like a named date with the source obligation, not "as soon as possible."

3. Confirm your lender's appraiser policy

For federally-regulated commercial lenders and Ontario credit unions, the appraiser must be on the lender's approved AACI panel. RBC requires a "bank-approved appraiser" (RBC Royal Bank, 2026); FSRA's Commercial Lending Guidance directs Ontario credit unions to use appraisers "with credentials issued by the Accredited Appraiser of the Canadian Institute" (FSRA, 2024). Why it matters: a non-panel appraiser can produce a perfect CUSPAP-compliant report the lender will not accept - and you pay twice. Completeness looks like written confirmation from the lender's underwriter that the appraiser is approved, in advance.

4. Request a draft scope of work

Before signing, ask the appraiser to summarize scope in plain language: report type (form, concise, or comprehensive under CUSPAP 2026 s. 7.5.3), inspection scope (desktop, drive-by, exterior, or interior-and-exterior), approaches to value, and any extraordinary assumptions anticipated. Why it matters: scope is the most common source of mid-engagement creep. Completeness looks like a one-paragraph scope description inside the engagement letter.

Before the site visit

Six items the appraiser will request. The file moves measurably faster when they are packaged before kickoff rather than chased afterward.

5. Current rent roll

Tenant, suite, leased area, base rent (monthly and per square foot annualized), commencement and expiry dates, renewal options, step-ups, security deposit, and any percentage-rent or recovery structure. Why it matters: the income approach is grounded in the rent roll. Completeness looks like a single spreadsheet, current within 30 days, that ties to the T12 income statement.

6. Executed lease copies and abstracts

PDFs of every active lease, plus amendments, estoppels, and recent assignments. For more than six tenants, a one-row-per-lease abstract (rent, recoveries, renewals, exclusive-use, restoration) is what the appraiser reads first. Why it matters: lease abstraction is the largest time sink in income-approach work. Completeness looks like every lease and amendment in one indexed folder.

7. Trailing twelve-month operating statement plus the prior two annuals

Rental income, recoveries, vacancy and bad debt, and operating expenses by category (realty taxes, insurance, utilities, R&M, management, professional fees). Why it matters: the appraiser reconciles reported expenses against market norms to derive stabilized NOI; three years surfaces non-recurring items that must be normalized. Completeness looks like accountant-prepared or PM-system-exported statements that reconcile.

8. Capital expenditure history and forward plan

Roof, HVAC, parking-lot, elevator, fire-system, recladding, and TI allowances paid - three to five years back, plus items expected within five years. Why it matters: capex history informs effective age, remaining economic life, and reserves-for-replacement reasoning. Completeness looks like a dated list with amounts and one-line descriptions.

9. Property tax bills - current and prior two years

The MPAC notice of assessment, the current municipal tax bill, and any active appeals. Why it matters: realty taxes are usually the single largest operating expense line, and active appeals signal possible stabilization. Completeness looks like the most recent MPAC notice and tax bill plus documentation of any appeal in flight.

10. Environmental and structural reports

Any Phase I or Phase II ESA, designated-substance survey, building condition report, structural review, roof inspection, or geotechnical study from the past five to ten years. Why it matters: federally-regulated lenders frequently require a passing Phase I ESA - RBC names it directly (RBC Royal Bank, 2026). Surfaced early, a contamination issue can be scoped or quantified; surfaced late, it can stop a transaction. Completeness looks like every environmental and structural document you hold.

During and after the site visit

Four items shape the field portion of the assignment and the delivery that follows.

11. Walk the property with the appraiser

Send someone who knows the building - the owner, property manager, or operator - not a leasing agent who has never been to the mechanical room. Why it matters: fit-out variations, hidden systems, recent capital work, and operational quirks surface fastest in conversation during the inspection. Completeness looks like the right person on site with keys to mechanical and storage areas.

12. Flag known issues during the walk-through

A known underground oil tank, an unresolved tenant dispute, a co-ownership agreement, a head-lease structure, a pending expropriation - say so during the inspection. Why it matters: surfaced upfront these become extraordinary assumptions disclosed correctly inside CUSPAP scope; surfaced two weeks in they trigger re-scoping and timeline slippage. Completeness looks like a short "things you should know" memo handed to the appraiser at or before the site visit.

13. Designate a single point of contact

One person - by name, with phone and email - who can answer follow-up questions. Not a generic inbox. Why it matters: a comprehensive commercial appraisal generates five to twenty clarifications between site visit and draft; routing them through one informed person is the difference between a four-week and a six-week turnaround. Completeness looks like a named contact with authority to answer questions about leases, expenses, and capital work without escalation.

14. Get the facts right upfront - there is no client draft

The deliverable is the final AACI-signed report, not a draft circulated for comment. We do not provide draft reports for client review, and a client should not expect one - the appraiser's independence is the value of the report, and a signed conclusion is not a negotiating document. Why it matters: because there is no draft stage to catch them, factual inputs - square footage, lease terms, capex amounts, recovery structures - have to be right while the file is open. Surface any correction during document discovery or at the inspection, not after delivery. Completeness looks like every factual input verified and handed over before the report is finalised, routed through your single point of contact.

What the AACI needs you to know upfront - the deal-breakers

Three categories of issue change the assignment fundamentally. Flag them at the discovery call.

Environmental issues. Known or suspected contamination, an underground storage tank, a former industrial use, asbestos or designated-substance presence, or an active Phase II investigation. A federally-regulated lender will typically require a passing Phase I ESA regardless (RBC Royal Bank, 2026). The appraisal can sometimes proceed under an extraordinary assumption that the environmental condition is as represented - but only with explicit CUSPAP disclosure.

Leasehold complications. A head-lease/sublease structure, a long-term ground lease, unusual restoration or recapture clauses, a contested renewal option, or a pending termination dispute. These reshape the income approach and can require a leasehold-vs-leased-fee allocation that doubles analytical work.

Partial-interest valuations. A co-ownership share, a partnership-buyout, a matrimonial half-interest, a remainder interest after a life estate. The appraiser must address marketability and minority-interest discounts and CUSPAP-disclose the partial-interest scope. This is a different assignment than a whole-property valuation and prices accordingly.

Frequently asked questions

How long does this checklist take to complete?

Most Ontario commercial owners can assemble the before-the-site-visit items in two to five business days from existing property-management records. Items 1-4 take a single discovery call.

What if my property is owner-occupied and I have no rent roll?

For owner-occupied commercial property, the income approach is built on market rent reasoning rather than a contract rent roll. The other documentation still applies. Flag at discovery that the property is owner-occupied. See documents needed for a commercial appraisal.

Can I provide partial information and let the appraiser request the rest?

You can - but it slows the file. Every round-trip for missing documents adds calendar days, which feeds commercial appraisal turnaround time. Owners who deliver the full package at kickoff see materially faster turnaround.
