What is an apartment building appraisal?
An apartment building appraisal is a written opinion of market value prepared by a licensed or certified appraiser under the Uniform Standards of Professional Appraisal Practice, known as USPAP. Federal banking rules treat any loan not secured by a single 1-to-4 family home as a commercial real estate transaction, so a 5+ unit building gets a commercial appraisal, not the residential form used for houses.
The report is a full analysis of the building as an income property. It covers the market, the site and improvements, the rent roll and operating history, and then three valuation approaches that the appraiser reconciles into one value. Our apartment building value calculator gives you a quick estimate; the appraisal is the version a lender will actually lend against.
Who orders a commercial real estate appraisal?
The lender orders the appraisal, even though the borrower usually pays for it. Federal rules for regulated banks say a fee appraiser must be engaged directly by the institution or its agent and can’t have any interest in the property or the transaction. That’s why an appraisal you commission yourself usually can’t be used for the loan.
When you sell, the buyer’s lender orders the appraisal, and you won’t see the report unless the buyer shares it. When you refinance, your lender orders it; ask up front whether you’ll receive a copy. Fannie Mae, Freddie Mac and HUD lenders follow their own program appraisal requirements on top of the banking rules.
When is an appraisal required? The FIRREA thresholds
Under the federal appraisal rules adopted under FIRREA, a regulated lender needs an appraisal for a commercial real estate loan above $500,000, and transactions at or below that amount need only an evaluation. The OCC rule at 12 CFR 34.43 sets the $500,000 commercial threshold, requires a state-certified appraiser above it, and requires one for every federally related transaction of $1,000,000 or more.
Almost every 5+ unit loan clears the $500,000 threshold, so in practice you should expect a full appraisal by a certified appraiser. The rules also require the appraisal to conform to USPAP and be reviewed for compliance with it.
| Loan amount (commercial real estate) | What the federal rule requires |
|---|---|
| $500,000 or less | An evaluation consistent with safe and sound practices |
| Over $500,000 | An appraisal by a state-certified appraiser |
| $1,000,000 or more | An appraisal by a state-certified appraiser |
What USPAP requires of the appraiser
USPAP is the set of standards published by The Appraisal Foundation’s Appraisal Standards Board, and the federal rules require lender appraisals to conform to it. The 2024 edition is the current one, and it no longer carries a fixed expiration date; it stays in effect until the board adopts revisions.
USPAP affects an owner in three ways. The appraiser must be independent and can’t be pushed toward a number. The report must disclose the scope of work, the data and the reasoning behind each approach. And because the lender is the client, the appraiser answers to the lender, which shapes how you challenge a value.
What documents sellers provide for an appraisal
The appraiser builds the building’s NOI from your records, so complete, consistent documents are the best thing you can do for the value. Expect a request for most of these:
- A current rent roll with unit numbers, unit types, lease dates, rents, concessions and deposits.
- Trailing 12-month operating statement, plus the last two or three years of annual statements.
- The current-year budget and a list of recent capital improvements with costs and dates.
- Property tax bills and any pending appeals.
- Utility bills and how utilities are billed back to tenants.
- Service contracts: laundry, parking, trash, landscaping, cable or internet.
- Insurance premium, management agreement and fee.
- Unit mix, square footage, site plan and any known deferred maintenance.
- Access to a sample of units, common areas, roofs and mechanical rooms.
How appraisers apply the three approaches
Appraisers develop the income, sales comparison and cost approaches, then give the most weight to the one that best reflects how buyers price the property. For a stabilized apartment building, that’s almost always the income approach.
In the income approach, the appraiser builds a stabilized NOI and capitalizes it with a market cap rate. Larger or value-add assets may also get a discounted cash flow analysis. In the sales comparison approach, the appraiser adjusts recent sales for location, age, condition, size and unit mix, often comparing price per unit, price per square foot and gross rent multiplier. The cost approach adds land value to the replacement cost of the buildings, minus depreciation. It’s most useful for new construction and gets little weight on older buildings, where depreciation is hard to measure.
How appraisers pick cap rates and comps
Appraisers pick a cap rate mainly by extracting it from comparable sales, dividing each comp’s NOI by its price, then adjusting for differences from your building. They often check it against investor surveys and a band-of-investment calculation that blends current loan terms with the return equity buyers expect.
The NOI matters as much as the rate. Appraisers normalize your numbers: they charge a market management fee even if you self-manage, add replacement reserves, use market vacancy instead of a perfect month, and reset property taxes when a sale will trigger a reassessment. Expect the appraiser’s NOI to be lower than the one in your marketing package.
Good comps are recent arm’s-length sales of similar buildings in the same submarket. A sale from two years ago, a portfolio sale or a distressed sale needs heavy adjustment or gets thrown out. If you know of strong recent sales, get them to your broker or lender early.
Worked example: reconciling three approaches on a 32-unit building
Take a 32-unit building with average rent of $1,750. Potential gross rent is $672,000 a year. The appraiser deducts 5% for vacancy and credit loss, $33,600, and adds $18,000 of laundry and parking income for effective gross income of $656,400. Normalized expenses at 40% are $262,560, so NOI is $393,840. At a 6.25% cap rate, the income approach indicates $6,301,440, rounded to $6,300,000.
Three comparable sales adjust to $192,000, $201,500 and $197,000 per unit. The appraiser concludes $196,500 per unit, leaning on the closest comp, so the sales comparison approach indicates $6,288,000. For the cost approach, 28,800 square feet at a $230 replacement cost is $6,624,000. Depreciation of 40%, from 22 years of effective age over a 55-year life, is $2,649,600. Adding $1,100,000 of land gives $5,074,400.
In reconciliation, the appraiser gives the income approach 60% weight and sales comparison 40%, and gives the cost approach no weight because the building is 22 years into its life. That’s $3,780,000 plus $2,515,200, or $6,295,200, and the final value is rounded to $6,300,000.
| Approach | Indicated value | Weight | Weighted value |
|---|---|---|---|
| Income ($393,840 NOI at 6.25%) | $6,300,000 | 60% | $3,780,000 |
| Sales comparison ($196,500 × 32 units) | $6,288,000 | 40% | $2,515,200 |
| Cost (land + depreciated replacement cost) | $5,074,400 | 0% | $0 |
| Reconciled | 100% | $6,295,200, rounded to $6,300,000 |
Appraisal vs BOV vs broker opinion of value
An appraisal is a USPAP-compliant opinion from a certified appraiser that a lender can rely on; a broker opinion of value, or BOV, is a broker’s pricing estimate meant to win a listing or guide a sale. A BOV can be useful and is often free, but a regulated lender can’t lend against it.
| Appraisal | BOV or broker opinion | |
|---|---|---|
| Prepared by | State-certified or licensed appraiser | Real estate broker |
| Standard | USPAP | No appraisal standard; broker’s judgment |
| Client | Usually the lender | Usually the owner |
| Used for | Loans, estates, litigation, tax | Listing price, sale strategy |
| Cost | A paid professional fee | Often free |
| Bias risk | Independence rules apply | May lean high to win the listing |
How to challenge a low appraisal: reconsideration of value
A reconsideration of value, or ROV, is a formal request asking the appraiser, through the lender, to review a value using information they missed or got wrong. The 2024 interagency ROV guidance from federal bank regulators covers residential valuations, so on an apartment loan you’ll follow the lender’s own process. Send the request to the lender, not straight to the appraiser.
Small changes make big swings. In the example above, if the appraiser had used a 6.75% cap rate, the income approach would drop to about $5,834,667, or roughly $5,830,000. At 75% loan to value, the loan would fall from $4,725,000 to $4,372,500, a $352,500 gap. A strong ROV shows why a different rate is justified.
- Read the full report and list factual errors: unit count, square footage, rents, expenses.
- Gather sales the appraiser missed, with prices, dates, NOI and cap rates.
- Show why the NOI or cap rate is off, using leases, the rent roll and the operating history.
- Submit one organized package through the lender and ask for a written response.
- If the value stands, ask the lender about a review appraisal or a second appraisal.
How an appraisal affects selling a 5+ unit apartment building
When you sell, the buyer’s lender appraisal can reopen the price. If it comes in below the contract price, the buyer may need more equity, ask for a price cut or walk under an appraisal or financing contingency. Pricing the building on realistic, normalized NOI is the best protection.
You can also limit the risk in the contract. Shorten or drop the appraisal contingency, ask for proof of the buyer’s equity, or offer seller financing for part of the price so the buyer needs a smaller loan.
