Commercial appraisals: how lenders use them and how to prepare
Spencer Thomas ·

The appraisal is often the single report that decides how much a lender will lend. A term sheet may quote a loan amount, but that number usually rests on an assumed value. If the appraisal comes in lower, the loan gets smaller, and the borrower has to fill the gap late in the process. Understanding how appraisers think, and preparing for them, is one of the simplest ways to protect a closing.
Why the appraisal matters so much
Most commercial and investment property loans are sized on more than one test. Loan to value is almost always one of them. The lender takes the appraised value, applies its maximum leverage, and that sets a ceiling on proceeds.
A few points are worth knowing:
- The lender orders the appraisal, not the borrower. The appraiser works for the lender and owes its duty to the lender.
- The borrower usually pays for it, often before a commitment is issued.
- The appraised value can differ from the purchase price, a broker opinion, or a tax assessment. The lender will use the lower of value or cost on many acquisitions.
On a purchase, a strong appraisal rarely increases the loan beyond the price. A weak one can reduce it.
The three approaches to value
Appraisers typically consider three methods and then reconcile them into one conclusion.
Income approach
This is the primary method for most income producing property. The appraiser estimates stabilized net operating income and converts it to value, usually by applying a capitalization rate drawn from market evidence. The appraiser builds the income from the rent roll, leases, and operating history, then normalizes it. That can mean adding a vacancy allowance, management fees, and replacement reserves even if the owner does not pay them today.
Sales comparison approach
Here the appraiser looks at recent sales of similar properties and adjusts for differences in size, location, age, condition, and timing. It carries more weight for owner occupied buildings, small properties, and land.
Cost approach
This estimates what it would cost to replace the improvements, less depreciation, plus land value. It matters most for newer buildings, special purpose properties, and construction loans.
Where values come in low
Low appraisals usually trace back to a handful of issues:
- Income the appraiser cannot verify, such as cash rents, side agreements, or units not reflected in the rent roll.
- Expenses that look unusually low compared with similar properties.
- Leases near expiration, below market rents, or concentration in a single tenant.
- Deferred maintenance noted at the site inspection.
- A business plan that depends on future rent growth the appraiser will not credit yet.
- Thin or dated comparable sales in smaller markets.
On value add or construction deals, ask whether the lender wants an as is value, an as stabilized value, or both. Loan proceeds are often tied to each one differently.
How to prepare
Owners cannot steer an appraisal, and should not try. They can make sure the appraiser has complete and accurate information. That alone prevents many surprises.
- Provide a current, signed rent roll and copies of all leases and amendments.
- Share two to three years of operating statements plus a current year to date.
- Document recent capital improvements with invoices and dates.
- List any pending leases, renewals, or tenant improvements in progress.
- Make the property easy to tour, with access to all units and mechanical areas.
- Run your own sizing first, using a conservative value, so you know what a lower number would mean for the loan.
If the report contains a factual error, such as wrong square footage or a missed lease, you can ask the lender to send the correction to the appraiser. Disagreeing with the appraiser's judgment is a different matter and rarely succeeds. The better defense is preparation before the inspection, not argument after the report.
Plan for the gap before it appears
A careful borrower assumes the appraisal could land below expectations and decides in advance how to respond. Options may include more equity, a smaller loan with a different lender, seller financing, or a preferred equity piece. Knowing your fallback keeps a low number from becoming a crisis.
