If you’ve ever asked a broker, “What’s this property worth?” and gotten an answer within a week or so, you didn’t receive an appraisal. You got an opinion of value. The two terms are used interchangeably in casual conversation, but they’re built differently. We use them for different things, and confusing one for the other can cost you time or money, depending on which side you’re on.
Here’s the distinction, and where each one fits.
What is an Opinion of Value?
A broker’s opinion of value — sometimes called a broker price opinion (BOV) — is just what it sounds like. It’s an estimate of what a property is worth, based on that broker’s read of the market, recent comparable sales, and the property’s condition and income potential.
It’s informal by design, but that’s the point:
- No licensing board requiring a specific format.
- No regulatory body signing off on the methodology.
- Often no fees involved, since brokers frequently put BOVs together for free because they hope to win the listing.
A BOV gives owners, attorneys, or courts a fast, market-based number without the time or cost of a full appraisal.
What is an Appraisal?
An appraisal is a formal valuation conducted by a state-licensed or certified appraiser, governed by the Uniform Standards of Professional Appraisal Practice (USPAP). It follows a structured process:
- A physical inspection.
- Market research.
- A comparable sales analysis.
- A written report that must meet specific professional standards.
Lenders generally require one before financing a purchase because an appraisal carries legal and financial weight that a broker’s opinion does not. That weight comes at a cost in dollars and time. Appraisals cost several hundred to several thousand dollars, depending on the property. They take longer to produce because of the formal documentation involved.
Where the real difference appears
A BOV and an appraisal serve different purposes, but each is helpful depending on where you are in the selling (or buying) process. A broker who knows a submarket really well can often land closer to the eventual sale price than a generic appraisal that leans too heavily on outdated comps.
An appraisal answers the question, “What is the defensible, certified value of this property?” A bank, court, or the IRS wants that answer before money changes hands. A BOV answers, “What will this property sell for in this market, right now, to a buyer?”
While the brokers doing this work are running comps as part of their research, they also factor in things that don’t always appear cleanly in an appraisal report:
- Deferred maintenance
- A below-market tenant that must be dealt with
- Vacancy that must be resolved before the building performs the way the numbers suggest it should
That second number — the one grounded in what a real buyer will pay today — is often more useful for a seller deciding how to price a listing or a court deciding a disputed asset’s value in a sale. It’s less useful for a lender who needs a standardized, third-party-verified figure to underwrite a loan.
Why this situation arises more often than people expect
Attorneys handling estate disputes, partnership dissolutions, or contested ownership situations often need a value figure before a buyer enters the picture. A formal appraisal is one option. A broker’s opinion of value, especially from someone who actively sells in that asset class and market, is often faster and just as useful for settling the question internally before the property ever hits the market.
It also comes up in situations unrelated to litigation.
- An owner considering a sale wants a gut check before committing to a listing price.
- A buyer evaluating several properties at once wants a quick read on each without paying for five separate appraisals.
- A partner buying out another partner needs a number that both sides can work from before they call their lawyers.
None of these situations requires the certified weight of a formal appraisal. They require a number grounded in current market dynamics, delivered expeditiously enough to be useful.
The broker’s opinion can diverge significantly from the eventual sale price, and it’s worth sitting with, rather than treating as a contradiction. A property might carry a BOV well above what it finally sells for, based on its income potential once it’s stabilized, fully leased, and free of deferred maintenance. That same property might trade at a lower price today because it has vacant space, a tenant paying below-market rent, or needs significant repairs or upgrades.
Both numbers can be correct. One reflects an asset’s value once it’s fixed. The other reflects what someone will pay for it as it sits. The gap offers information — it tells a buyer how much upside exists if they’re willing to stabilize the property, and it tells a seller what they’re being paid for.
What goes into each number
A broker offering an opinion of value doesn’t merely pull a few comps from a database and split the difference. They account for the property’s current, not theoretical, condition:
- How much of the building is currently occupied.
- Whether existing leases are at or below market rent.
- What it would cost to fix deferred maintenance.
- How long it would realistically take to find new tenants if the space turned over.
None of this data requires a license to evaluate. It does, however, require the experience and knowledge gained from having sold enough similar properties to understand what matters to buyers.
An appraiser works from a more standardized framework. The three traditional approaches — comparable sales, income capitalization, and replacement cost — are applied with documentation requirements that withstand scrutiny from a lender’s underwriting department (or a judge). That rigor explains why lenders require one. It also explains why an appraisal can sometimes lag behind the market. By the time the appraiser finishes a formal report, the comps on which it’s built may be a few months stale in a market moving quickly in a different direction.
Which report do you need?
If you’re financing a purchase, refinancing, or involved in a legal proceeding requiring a certified figure, you need an appraisal. Lenders and courts require it.
If you’re trying to calculate what to list a property for, deciding whether to sell at all, or settling a valuation question between parties before a sale is brought to the table, a BOV from someone active in that property type and that market offers a faster, more market-accurate starting point.
Many owners get both: a BOV early in the process to set expectations, followed by a formal appraisal once a deal begins moving toward financing.
Either way, the number tells only half the story. What also matters is understanding why the number is what it is and whether you’re analyzing value as it stands today or potential value once any work is complete.
