The commercial appraisal is the single third-party report most likely to change your deal, and the one borrowers understand least. It is not a home appraisal scaled up. It is a written analysis, frequently sixty to a hundred pages, that develops an opinion of value using multiple methods, states the assumptions behind it, and is addressed to the lender rather than to you.
It also sits on the critical path. Loan sizing is generally set on the lesser of purchase price or appraised value, so nothing final can be issued until the report is delivered and reviewed. Understanding the process lets you prepare for it, shorten it, and respond intelligently if the number disappoints. This walks through it in order.
Who orders it, and why you cannot
The lender engages the appraiser, through an independent channel insulated from the people who want the loan to close. That separation exists by regulation and it is not negotiable. You pay for the report (appraisal fees are a borrower cost) but you are not the client, you do not select the appraiser, and you generally cannot direct the scope.
An appraisal you commissioned yourself for a different purpose is usually not usable for the loan. It may still be worth having if you need a value for a partnership buyout or estate planning, but do not expect the lender to accept it. The same is true of a prior appraisal ordered by a different lender, unless it can be transferred and re-certified, which varies by institution.
The three approaches to value
A commercial appraiser develops value through up to three approaches and then reconciles them into a single conclusion, explaining which carried the most weight and why. Knowing which approach will drive your property tells you what evidence matters.
The income approach
The dominant approach for income-producing property. The appraiser reconstructs a stabilized net operating income from the rent roll, the leases and market data, then converts it to value through a capitalization rate drawn from comparable sales and investor surveys, or through a discounted cash flow for larger or more complex assets. If your property is leased, this is the number that will drive the report.
The sales comparison approach
Recent sales of similar properties, adjusted for differences in size, age, condition, location and lease structure. It carries the most weight on owner-occupied and smaller general-purpose buildings, where a buyer pool is buying the building rather than an income stream. Its weakness is thin data: in slow submarkets there may be very few genuinely comparable transactions.
The cost approach
Land value plus the depreciated cost to reproduce the improvements. It matters most on new construction, on special-purpose facilities where neither income nor comparable sales are informative, and as a sanity check. On an older building it typically produces a value well above what anyone would pay, because accumulated depreciation is hard to estimate.
| Property situation | Primary approach | Supporting approach |
|---|---|---|
| Leased multi-tenant income property | Income | Sales comparison |
| Owner-occupied general-purpose building | Sales comparison | Income (as if leased) |
| New construction | Cost | Sales comparison |
| Special-purpose facility | Cost | Income, where any market rent exists |
| Vacant building being repositioned | Income, as stabilized | Sales comparison, as is |
As-is, as-stabilized, as-complete
A single report can contain more than one value, and the distinction drives loan sizing. As-is value is the property in its current condition and occupancy today. As-stabilized value assumes the property has reached normal market occupancy. As-complete value assumes planned construction or renovation has been finished according to submitted plans.
A vacant building might appraise at one number as-is and a materially higher one as-stabilized. Which value your loan is sized against depends on the structure. Short-term financing frequently advances against as-is with a holdback, and permanent financing is sized on stabilized performance once it is real. Assuming the stabilized number applies from day one is a recurring source of disappointment.
What the appraiser needs from you
You cannot influence the conclusion, but you absolutely can influence the quality of the inputs and the speed of delivery. An appraiser who has to reconstruct your rent roll from partial information will make conservative assumptions, and conservative assumptions produce lower numbers.
The appraisal package to have ready on day one
- Current rent roll with unit or suite, tenant, square footage, lease start and end, base rent, escalations and options.
- Copies of all leases and amendments, including any side letters or free-rent agreements.
- Trailing twelve to thirty-six months of operating statements and the current year budget.
- Property tax bills for the last two years and the current insurance declarations.
- A capital expenditure history: roof, HVAC, parking, structural and tenant improvement work with dates and amounts.
- Site plan, floor plans, building measurements and, if available, an ALTA survey.
- For construction or renovation: full plans and specifications, the contractor's budget, and permits.
- Environmental, condition or engineering reports already in hand.
- The purchase agreement, and any brokerage listing history including prior price reductions.
- A contact who can provide interior access on short notice.
Timing and cost
Commercial appraisals take longer and cost more than residential ones, and the range is wide because the work is genuinely different across property types. The figures below are illustrative and vary substantially by market, complexity, appraiser availability and lender requirements.
| Property type | Typical turnaround | Drivers of delay |
|---|---|---|
| Small general-purpose building, owner-occupied | Two to four weeks | Access, thin comparable data |
| Multi-tenant income property | Three to six weeks | Lease abstraction, incomplete rent roll |
| Special-purpose facility | Four to eight weeks | Few comparables, cost approach research |
| Construction or major renovation | Four to eight weeks | Plans, budget review, as-complete analysis |
The reports that travel with it
The appraisal rarely arrives alone. Expect an environmental screen that begins with a records review and escalates to a Phase I or further investigation if site history warrants; a property condition assessment on older or larger buildings; a title commitment and survey; and a flood determination that can trigger insurance requirements. Any of these can independently move your closing date.
There is also a review step after delivery. The lender's appraisal review (internal or independent depending on loan size and institution) checks methodology, comparable selection and assumptions. Review can send the report back for revision, which adds time.
When the number comes in low
This is the scenario worth planning for. Since loan sizing on a purchase is generally set on the lesser of contract price or appraised value, a low appraisal transfers the difference into your equity requirement, dollar for dollar times your leverage.
You have four moves, and they are not mutually exclusive. Renegotiate the price with the seller, using the appraisal as leverage. Bring additional cash. Reduce the loan request and change the structure. Or request a reconsideration of value.
How a reconsideration of value actually works
A reconsideration is a factual challenge, not an appeal of judgment. It succeeds when you supply data the appraiser did not have: a genuinely comparable sale that closed after the effective date of research, a lease that was signed but not recorded, a measurement error, a factual mistake about the improvements. It rarely succeeds when the argument is that the number should be higher.
Submit it through the lender, not directly to the appraiser, with the supporting documents attached and the specific error or omission identified. Expect it to take time and expect most reconsiderations to change nothing. Plan for the low number and treat any revision as upside.
Who owns the appraisal I paid for?
The lender is the client and the report is addressed to it, even though you are billed for the work. Most lenders will provide you a copy on request, and in many contexts they are required to. What you generally cannot do is take that report to another lender and expect it to be accepted without a transfer and re-certification.
Can I use an appraisal from a prior loan?
Sometimes, if it is recent enough, was prepared for a comparable purpose, and the appraiser will re-certify it to the new lender. Whether that is acceptable varies by institution and by how much the market has moved. Assume you need a new one and treat reuse as a bonus.
Why did the appraiser use comparables that seem wrong?
Comparable selection is constrained by what actually traded. In thin submarkets an appraiser may have to reach further geographically or further back in time and then adjust. If you know of a better comparable, provide the details through the lender. That is legitimate factual input and it is the most productive form of pushback.
Does a vacant building appraise for much less?
Usually yes on an as-is basis, because the income approach has little contractual income to work with and the sales comparison approach reflects lease-up risk and carrying costs. That is precisely why vacant or partially vacant properties are often financed short-term first and permanently later, once leases exist.
How current does the report have to be at closing?
Lenders set a maximum age, and if your closing slips past it you may need an update or a new report at additional cost. This is a real risk on deals with long diligence periods or construction. Ask the lender for the shelf life at the outset and manage the calendar against it.
What is an appraisal review and can it lower my value?
It is the lender's quality-control step on methodology and assumptions, performed internally or by an independent reviewer depending on loan size. A review can require revisions, and revisions can move the conclusion in either direction. Most commonly it adds time rather than changing the number.
Will the appraiser tell me the value on the inspection day?
No. The inspection is data collection; the analysis happens afterward and the conclusion goes to the lender. Asking for a preliminary number puts the appraiser in an awkward position and yields nothing useful.
How do I keep the appraisal from delaying my closing?
Have the package assembled before the order goes out, make access easy and immediate, respond to follow-up questions the same day, and negotiate a diligence period that reflects real commercial turnaround rather than a residential one. Most appraisal delays are access and document delays, not appraiser delays.
Where to start
Build the appraisal package before the order is placed: rent roll, leases, operating statements, tax and insurance, capital history, plans and survey, and put one person in charge of access. That alone routinely removes a week or two from the calendar.
Then run your own value estimate first, using the approach that will drive your property type. If your number and the seller's are far apart, you know before you spend money on third-party reports that the deal has a valuation problem, and you can negotiate while you still have room.
