What Makes an Appraisal Report Defensible? A Canadian Checklist

Written by Christopher J Bisson | Aug 10, 2026, 4:31:03 PM

Every report you sign carries your name for years. Long after the file closes, someone may pick it up: a lender's reviewer, a client's counsel, a regulator, or a colleague asking for a second opinion. A defensible report is one the reader can follow from evidence to conclusion without needing you in the room to explain it.

 

That is a high bar. A report can have every field filled and still leave a reviewer guessing why one comparable made the grid and another did not. The good news is that defensibility is mostly a documentation discipline, and it is one you can build into how you work rather than bolt on at the end.

 

Here is the checklist that holds up best when a report gets a second look.

 

1. Comparable selection a reader can retrace

Reviewers rarely challenge which comparables you chose. They challenge why. A grid of three sales with no visible search logic asks the reader to trust you. A short note on the parameters you searched, the radius and time window you accepted, and the reason you widened either one turns that trust into something checkable.

 

The sales you set aside matter as much as the ones you kept. If there was a closer sale that you rejected because it was a family transfer or a distressed disposition, say so. One sentence closes a question that would otherwise sit open in a reviewer's mind, and it demonstrates that you looked rather than settled.

 

2. Adjustments that explain themselves

Each adjustment needs three things: a stated basis, a sensible direction, and consistent application across the grid. The basis can be paired sales, market extraction, cost data, or reasoned judgment, and any of those is acceptable when you name it. What does not survive review is a number that appears without explanation, especially a large one.

 

Consistency is where most grids slip. If you adjusted $350 per square foot for living area on one comparable, the same rate should appear on the others unless something specific justifies the difference. Reviewers read down the columns, not just across the rows, and inconsistent rates are the first thing they notice.

 

By the way: if you figure out the value per square foot of living area after removing the land value for each comp, then say so. That's a good reason why the rate used in your adjustments for GLA might differ from comp to comp. But let the reader know that's what you've done by making it easy to ascertain that. Put it right in the comments section in the DCA, and call it out by making the text bold.

 

3. Photos that match the narrative

This is the most common quality gap, and it is the easiest to fix. If the narrative describes an updated kitchen, the photo set should show that kitchen. If the condition rating is average, the photos should not show active water staining or a roof at the end of its life. Where the words and the images disagree, a reviewer will believe the images and question everything else you wrote.

 

Completeness counts too. A missing rear elevation, an unphotographed lower level, or a comparable with no image invites a follow-up request at best. Before you deliver, read your own condition ratings and update language once with only the photos in front of you, and ask whether a stranger would reach the same description.

 

4. A report that answers the client's terms of reference

Clients differ in what they require, and their requirements are usually written down. Some want a specific exposure period commentary, some want a rental analysis on any property with a secondary suite, some want particular language when the subject is rural or on private services. A report that is excellent in general terms can still fail because it did not answer the question the client actually asked.

 

Treat the terms of reference as a checklist you clear before delivery, not as boilerplate you acknowledged at intake. The reports that come back for revision are very often the ones that were strong on valuation and thin on the client's specific instructions.

 

5. Internal consistency across the whole file

Gross living area, room counts, site size, effective date, and occupancy each tend to appear in several places in a report. When a bedroom count in the narrative disagrees with the grid, or the effective date differs from the inspection date, the error itself is usually minor. The damage is to confidence. A reader who finds one contradiction starts hunting for others, and the value conclusion inherits that doubt.

 

6. A deliberate review pass before delivery

Deadline pressure is real, and the last hour before delivery is when consistency errors get made and missed. A structured pass through the report with fresh attention, checking the narrative against the grid, the grid against the photos, and all of it against the terms of reference, catches most of what would otherwise come back as a revision request. It takes far less time than answering a revision request does.

 

Where the software you write in makes a difference

Most of this checklist is judgment, and no tool replaces it. What a report writing tool can do is carry the parts that are purely mechanical: keeping a figure consistent everywhere it appears, keeping the photo set organized against the narrative it supports, and making the client's requirements visible while you write rather than after you finish.

 

That is the thinking behind valique (pronounced Val-I.Q.), the report writing software we have been building at Value Connect. It was shaped by feedback from dozens of appraisers over hundreds of hours of design work, and it is built for Canadian practice in both official languages. Stay tuned for more details as we roll it out!

 

The checklist, short version

  • Can a reader retrace why these comparables made the report, and not others?
  • Does every adjustment state a basis, point the right way, and apply consistently?
  • Do the photos support every condition and update claim in the narrative?
  • Is the photo set complete, including each comparable?
  • Does the report answer this client's terms of reference specifically?
  • Do the numbers agree everywhere they appear?
  • Did someone look at the finished file with fresh eyes before it went out?

None of this is exotic. It is the difference between a report that answers questions and one that raises them, and it is worth the twenty minutes it costs.

Value Connect works with appraisers across Canada. If you would like to hear when valique opens for early access, get in touch with our team.
