Quick answer
A desktop appraisal is built from the serial number, specification, hours and photographs, with no one attending. It is faster and cheaper and, because condition is assumed rather than seen, conservative. An on-site inspection costs more and takes longer, and is worth it when your equipment is genuinely better than average for its age.
The Trade in One Sentence
A desktop valuation assumes typical condition. An on-site inspection observes actual condition.
If your equipment is typical, those produce nearly the same number and the desktop saves you time and money. If your equipment is meaningfully better than typical — low hours, documented major work, careful storage — the desktop cannot know that and prices as though it were not true.
So the decision is not really about cost. It is about whether you have something to prove.
How They Compare
| Desktop | On-site | |
|---|---|---|
| Built from | Serial, spec, hours, photographs, comparable sales | A physical inspection, plus all of that |
| Turnaround | Fast | Slower — scheduling plus travel |
| Cost | Lower | Higher |
| Condition | Assumed typical | Observed and recorded |
| Bias | Conservative | Reflects what is actually there |
| Suits | Common, liquid, average-condition assets | Large, specialised, or better-than-average assets |
When the Desktop Is Enough
- The equipment is a common model with an active resale market
- Age and hours are unremarkable for the type
- The loan is modest relative to the cost of an inspection
- Speed matters — a desktop can turn round in a fraction of the time
- You are sizing a deal rather than closing one, and want an indication
For a five-year-old skid steer with average hours, an inspector is unlikely to find anything the comparable sales did not already imply. Paying for one buys very little.
When the Inspection Pays for Itself
- The equipment is better than its age suggests — low hours, indoor storage, a documented rebuild
- It is specialised, so comparable sales are thin and a desktop has little to work from
- The loan is large, and a percentage improvement in the valuation is worth more than the fee
- Several units are involved, where one visit covers the fleet
- The desktop came back low and you believe it is wrong
That last case is the most common reason to escalate. A desktop figure is an opinion formed without seeing the asset; an inspection is the evidence that rebuts it. Disagreement alone moves nothing — evidence does.
How Long Each Takes, and Why It Matters
Turnaround is the other axis, and on a time-sensitive deal it can decide the choice regardless of accuracy.
A desktop valuation is largely research: pull the comparables, read the photographs, write it up. The constraint is the appraiser's queue rather than logistics, so it moves quickly once instructed.
An on-site inspection adds scheduling, travel and a site visit that has to fit around your operation as well as theirs. Equipment in daily use, spread across sites, or in a remote location adds days before anyone has looked at anything — and if a machine is out on a job when the inspector arrives, it adds a return trip.
Two practical consequences. If the equipment is working, coordinate the visit around a day it will actually be on the yard. And if a deadline is genuinely tight, ask whether the lender will proceed on a desktop figure and treat an inspection as a condition afterwards — some will, at a more conservative advance.
Making Either One Land Well
You have more influence over a desktop valuation than most owners realise, because you supply most of its inputs.
- Photograph properly. Clean, well lit, every angle, plus the data plate and the hour meter. Poor photographs produce conservative numbers.
- Send the service file without being asked. Documented work you cannot evidence counts as work that did not happen.
- Give exact identifiers — serial number, model and year. Approximations get valued as the weaker interpretation.
- Disclose the flaws. An appraiser who finds something undisclosed discounts everything else you said.
- Fix the cheap things before an on-site visit. Warning lights and leaks read as deferred maintenance across the whole machine.
Frequently Asked Questions
What is a desktop equipment appraisal?
A valuation produced without attending — built from the serial number, specification, hours, photographs and comparable sales. It is faster and cheaper, and conservative, because condition is assumed rather than observed.
Is an on-site appraisal worth the extra cost?
When your equipment is genuinely better than average for its age, when it is specialised enough that comparable sales are thin, or when the loan is large enough that a percentage improvement exceeds the fee. For an average machine on a modest loan, usually not.
Why did my desktop appraisal come back low?
Because it assumes typical condition, and typical is not generous. Poor photographs, missing service history or approximate identifiers all push it further down, since the appraiser resolves uncertainty conservatively.
Can I challenge a desktop valuation?
With evidence, yes — comparable sold units of the same model and specification, documented major work, or an on-site inspection. Disagreement on its own does not move a valuation; evidence does.
What should I send for a desktop appraisal?
Clean, well-lit photographs from every angle including the data plate and hour meter, the exact serial, model and year, and the service file. Disclose known faults — an appraiser who finds something undisclosed discounts the rest of what you said.
