The quick read: A commercial real estate appraisal for a loan works like this: the lender, not you, selects and engages a certified appraiser, the appraiser values the property with the income, sales comparison and cost approaches that apply, and the lender reviews the report before it makes a credit decision. The value it accepts becomes the denominator of your loan-to-value ratio, and on a purchase that value is the lesser of the price or the appraisal. Because most income property is valued on net operating income divided by a cap rate, a half-point change in the appraiser's cap rate can move your loan by six figures.
This page covers who orders the appraisal, how each approach works, when a cheaper evaluation is allowed and how the lender reviews the report. If the number has already come back short, go to what happens if a commercial property appraisal comes in low.
How does a commercial real estate appraisal work for a loan?
A commercial real estate appraisal for a loan is an independent opinion of market value that the lender commissions, reviews and then uses to cap your loan, so the appraised value, not your offer price or your own pro forma, decides how much the property can borrow. You see the result through the loan-to-value ratio.
The sequence runs in four steps for an acquisition or a refinance of an existing building:
Step 1: you sign a term sheet or application, and the lender engages an appraiser it selects
Step 2: the appraiser inspects the property, reads the rent roll, leases and operating statements, and develops each approach to value that applies
Step 3: the lender's reviewer checks the methods, assumptions and data, and resolves any deficiencies before the credit decision
Step 4: the accepted value is divided into the requested loan to test the loan-to-value ratio
The investor decision sits behind every step. If you are buying, the value tests whether your price is supported. If you are refinancing, it sets how much equity you can pull out or how much you must bring in. The Office of the Comptroller of the Currency's Commercial Real Estate Lending handbook (Version 2.0, March 2022) states the purchase rule plainly: for loans to purchase an existing property, value means the lesser of the actual acquisition cost or the estimate of value. Pay more than the appraisal supports and the lender sizes your loan on the appraisal, so the gap comes out of your equity.
Who orders the appraisal, and can you pick the appraiser?
The lender orders the appraisal and picks the appraiser, and you cannot: federal interagency guidelines say an institution or its agent must directly select and engage appraisers, and that independence is compromised when a borrower recommends one. You can supply documents and access, but you do not choose who values the building.
The Interagency Appraisal and Evaluation Guidelines, published by the Federal Reserve with the other banking agencies, allow one exception. A lender may use an appraisal prepared for another financial services institution if that institution, not the borrower, ordered it, the appraiser had no interest in the property and the report meets the agencies' rules. That is why a report you commissioned yourself, or one the seller hands you, will not carry a regulated loan. Whether a prior lender's report can travel with you is covered in can you reuse an appraisal if you switch commercial lenders.
What you control is the file the appraiser reads. Send a current rent roll, trailing operating statements, copies of every lease, a list of recent capital work and any approved plans on the day the appraiser is engaged. An appraiser who has to estimate rents from market data, because the leases never arrived, values the building on assumptions instead of contracts.
How do the income, sales and cost approaches work?
An appraiser values commercial property with three approaches, income, sales comparison and cost, and the interagency guidelines require every approach that is applicable and necessary to the assignment, with a reconciliation of the results and a stated reason for any approach left out. For leased income property the income approach usually carries the most weight.
The OCC handbook defines each one. The income approach converts expected net operating income into present value through direct capitalization, which divides NOI by a cap rate, or through discounted cash flow, which discounts future NOI over a holding period and adds the expected net sale price. Direct capitalization fits a stabilized NOI; discounted cash flow fits a property that has not reached stabilized occupancy or whose income will swing. The sales comparison approach compares the subject to at least three recently sold similar properties in the area, and the cost approach adds land value to construction cost, less depreciation.
Table: Commercial appraisal approaches and the values a lender may request
| Approach or value | What it measures | Key input | Best for |
|---|---|---|---|
| Approach or value Income, direct capitalization | What it measures Value of a stable income stream | Key input Stabilized NOI and a cap rate | Best for Leased, stabilized buildings |
| Approach or value Income, discounted cash flow | What it measures Present value of changing income plus a sale | Key input Projected NOI, discount rate, net sale price | Best for Lease-up, rollover or uneven income |
| Approach or value Sales comparison | What it measures What similar buildings sold for | Key input At least three recent comparable sales | Best for Properties that trade often |
| Approach or value Cost | What it measures Land plus construction cost, less depreciation | Key input Land value, building cost, depreciation | Best for New or special-purpose buildings |
| Approach or value As-is versus as-stabilized | What it measures Value today versus after construction or lease-up | Key input Current condition, and the business plan | Best for Renovation and bridge loans |
The cap rate is the input to watch. Our arithmetic below is illustrative, with cap rates chosen to show the mechanism rather than to quote any market:
NOI: $300,000
Value at a 7.0% cap rate: $300,000 ÷ 0.070 = $4,285,714, about $4.29 million
Value at a 7.5% cap rate: $300,000 ÷ 0.075 = $4,000,000
Loan at 75% LTV: about $3.21 million at the lower cap rate, $3.0 million at the higher one
A half-point difference in the appraiser's cap rate costs about $214,000 of loan proceeds on the same building and the same income. The handbook notes that rising interest rates may lead to higher cap rates and lower values without any change to the property itself. Run your own numbers in the cap rate calculator before the appraisal is ordered, so you know which cap rate your requested loan needs.
As-is and as-stabilized values matter most on transitional deals. For construction or renovation, the guidelines say a lender would generally ask for the current as-is value and, as applicable, prospective values upon completion and upon stabilization. Which of those values, and whether it is set against value or cost, limits a bridge loan is worked through in LTV vs LTC on a bridge loan.
When is an evaluation enough instead of an appraisal?
An evaluation can replace a full appraisal when a regulated bank makes a commercial real estate loan of $500,000 or less, or a business loan of $1 million or less that is not repaid primarily from the sale of, or rent from, real estate, under 12 CFR 34.43. Above those lines a state certified appraiser is required.
The rule reads in four parts. Section 34.43(a)(13) exempts commercial real estate transactions with a transaction value of $500,000 or less from the appraisal requirement. Section 34.43(a)(5) exempts business loans of $1 million or less that do not depend on the real estate for repayment, which is the typical owner-occupied case where the operating business pays the loan. Section 34.43(b) then requires an appropriate evaluation for those exempt transactions, consistent with safe and sound banking practices. Section 34.43(d)(2) says commercial real estate transactions of more than $500,000 require an appraisal prepared by a state certified appraiser.
An evaluation is still a valuation of the collateral. The guidelines say it should estimate market value in the property's actual physical condition, use and zoning as of its effective date. It is simply not a full appraisal report. Two practical points follow for an investor. First, the threshold is a floor set by regulation, not a ceiling on what a lender asks for, so many lenders order a full appraisal on smaller loans anyway. Second, the rule binds regulated institutions; debt funds and other private lenders set their own valuation policies, and most rental property loans are repaid from rent, so the business-loan exemption rarely applies to them.
How does the lender review the commercial appraisal report?
The lender reviews the commercial appraisal before it decides on the loan, checking that the methods, assumptions and data sources are reasonable and well supported, and the interagency guidelines say that when it holds more than one valuation it should rely on the most credible report, not the one with the highest value.
The guidelines set out the review in detail. As part of the credit approval process and before a final credit decision, the institution should review appraisals and evaluations for compliance with the regulations, its own policies and supervisory guidance. Reviewers should be independent of the transaction and insulated from loan production staff. Commercial transactions involving complex properties, large-dollar credits, specialized property types or properties outside the lender's usual market should get a more comprehensive, technical review.
When the reviewer finds a problem, the lender asks the appraiser to correct it. A deficiency that cannot be resolved is handled with a second appraisal or a compliant appraisal review before the final credit decision. The guidelines also say a reviewer cannot change the value conclusion in the original appraisal. In practice that means arguing with the reviewer over the number rarely works; supplying a lease, an expense record or a comparable sale the appraiser missed, through the lender, is the route that can change the analysis. What to do if the reviewed value still lands short belongs to the low-appraisal guide.
Who can put your commercial deal in front of lenders before the appraisal is ordered?
A commercial mortgage brokerage can put your deal in front of several lenders before any of them orders an appraisal, so you see how each one sizes the loan and which value it is likely to need, instead of discovering the gap after paying for a report; there are two routes, and the brokerage route comes first.
- Brokerage route. YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors. Its software matches the deal against 20,000+ loan programs and typically returns 5–8 matches, so you can compare how several lenders size the same income before you pay for a report. Its brokers check the rent roll, leases and operating statements the appraiser will read, structure the request around a value the property can support, negotiate terms on your side and carry the deal toward closing. It is a 5-minute submit, with a median first offer in under an hour, from an institutional lender. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
- Direct route. Apply to one lender, accept its appraisal and its sizing, and repeat the process with the next lender if the value or the terms do not work.
Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
Submit your deal before the appraisal is ordered
The bottom line
A commercial real estate appraisal for a loan is ordered and reviewed by the lender, built from the income, sales comparison and cost approaches that apply, and used as the denominator of your loan-to-value ratio, with a purchase valued at the lesser of price or appraisal. Commercial real estate transactions above $500,000 at regulated banks need a state certified appraiser. Because the cap rate drives most income-property values, test your loan against a higher cap rate before the appraiser does, and hand over every lease and statement on day one.
