What is my commercial property worth?

A broker opinion of value for office, retail, industrial, multifamily, mixed-use and land in Florida and New York City, built from the evidence buyers will actually use.

How we value commercial property

Commercial property is not priced like a house. Buyers of income property start with the net operating income and the return they need. Owner-users compare the price to what it would cost to lease or build. Developers work backward from what the zoning allows. Most properties have more than one possible buyer, and the value is whatever the strongest of those groups will pay.

We prepare a broker opinion of value (BOV) for owners in Southwest Florida, Miami, Fort Lauderdale, Manhattan and Brooklyn. It is not an appraisal, and we say so in writing. It is a market-based estimate of what your property should sell for, how long it may take, and what could move the number. DiBe Real Estate is licensed in Florida and New York, and our principal is also a Florida Certified General Contractor, so building condition and improvement cost are part of the analysis.

Broker opinion of value or appraisal: which one you need

Owners often ask us for an “appraisal” when what they really need is a pricing opinion to decide whether to sell. The two documents answer different questions and are prepared by different professionals.

FocusBuyer pools, competing listings, marketing strategy and likely termsFormal methodology and a single supported value conclusion
Lender acceptanceNot accepted as an appraisal for lendingOrdered by the lender for loan underwriting

You need an appraisal when a lender, court, taxing authority, estate or partnership agreement requires one. You want a BOV when you are deciding whether, when and how to sell, or when you need a market reality check before talking to a lender or partner. Plenty of owners get both: a BOV to plan the sale and, later, the buyer’s lender orders the appraisal. Knowing how a BOV and an appraisal might differ helps you avoid surprises during the buyer’s financing.

The income approach: valuing a property by what it earns

Investors buy income. For leased property, the income approach is usually where the value conversation starts and ends.

Step one: net operating income

Net operating income (NOI) is the rent and other income the property collects, minus vacancy and credit loss and the operating expenses an owner pays. Operating expenses include taxes, insurance, repairs, management, utilities the owner covers and common area costs. NOI does not include mortgage payments, depreciation or the owner’s income taxes.

We rebuild NOI the way a buyer will. That means using market vacancy rather than assuming 100 percent occupancy forever, adding a management fee even if you self-manage, resetting property taxes to what a new owner is likely to pay after a sale, and using current insurance quotes. On leases, we check whether tenants actually reimburse what the lease says they should. Expenses on a tax return rarely match what a buyer underwrites.

Step two: the capitalization rate concept

A capitalization rate (cap rate) is the relationship between NOI and price. Buyers use it as shorthand for the return they expect and the risk they see. A lower cap rate means buyers will pay more for each dollar of income, which happens when the income looks safe and is likely to grow. A higher cap rate means buyers want more return because they see more risk: short leases, weak tenants, an old building, an expensive insurance picture or a soft location.

Cap rates are not a fixed number for a city or property type. They move with interest rates, lender appetite and buyer demand, and they vary widely within the same street depending on the lease and the building. We set the cap rate range for your property from recent sales and active buyer feedback, not from a published average.

When income alone is misleading

Below-market rents, a vacancy you are about to fill, a tenant about to leave or a lease with a large upcoming rent increase all change the picture. For those, we may look at value on current income and on stabilized income, and explain what a buyer will pay for the difference (usually less than the full upside, because they carry the risk).

The sales comparison approach

Comparable sales show what buyers have actually paid for similar property. We look for closed sales of the same property type, in the same submarket, as recent as possible. Then we adjust for what differs: size, age, construction, condition, frontage and visibility, parking, ceiling height and loading for industrial, lease status and the terms of the sale.

Comparable sales can be expressed per square foot of building, per unit for multifamily, or per buildable square foot or per acre for land. Each measure has blind spots. A price per square foot for a fully leased building and a vacant one of the same size can be far apart, so we never use a per-foot number alone.

In thin markets, such as a specialty building in a smaller city or a unique Brooklyn mixed-use property, good comparables are scarce. We say so in the BOV and lean more on the income and cost approaches, along with direct conversations with active buyers.

The cost approach and replacement cost

The cost approach asks what it would cost to build the same building today, less depreciation, plus the value of the land. Appraisers use it mainly for newer buildings and special-purpose properties. For owner-users, it is also how they think: if building new costs about the same as buying yours, they will often choose new construction unless yours is cheaper or available sooner.

This is where our construction background earns its keep. Our principal holds a Florida Certified General Contractor license and a Florida plumbing contractor license, so our replacement cost estimates come from building experience, not a cost manual alone. We look at what it would take to replicate the structure under current codes, including today’s wind load, flood elevation and energy requirements in Florida, or current building and zoning rules in New York. We also estimate what a buyer would spend to bring an older building up to the standard they need: roof, HVAC, electrical service, restrooms, ADA access, fire protection.

That improvement estimate matters as much as the replacement cost. Buyers deduct it from their price, often with a cushion. When we can show a realistic, contractor-backed number, the deduction is usually smaller than what a buyer would guess.

Land value and highest and best use

Sometimes the building is not the point. An older single-story retail building on a corner lot, a small industrial building on a large parcel, or a Brooklyn property with unused zoning floor area may be worth more to a developer than to someone who wants to keep running it as it stands.

Highest and best use is the legally permitted, physically possible, financially feasible use that produces the highest value. To test it, we look at:

  • Zoning: permitted uses, density, height, setbacks and parking requirements, and whether a rezoning or variance is realistic.
  • Site conditions: size, shape, access, utilities, wetlands, flood zone and any environmental history.
  • Market demand: whether there are buyers for what could be built, such as housing, self-storage, medical or industrial.
  • Cost and time: construction cost, approvals and impact fees, and how long it takes to entitle and build.

Developers value land by working backward: what the finished project will be worth, minus construction, soft costs, financing and profit. The remaining number is what they can pay for the land. If that number is higher than the value of your building as an operating property, your buyer pool is developers, and we market accordingly. See our development sites service for more.

What pushes commercial value up or down

Lease term remaining

Long leases with creditworthy tenants are worth more than short ones. A building with several leases expiring at once carries rollover risk, and buyers price it in.

Tenant credit

A national tenant, a stable medical practice or a government user supports a stronger price than a new local business with no track record. Personal and corporate guarantees matter too.

Lease structure

Net leases where tenants pay taxes, insurance and CAM protect the owner from rising costs. Gross leases leave that risk with the owner. Buyers adjust value for who carries which expense.

Deferred maintenance

An old roof, failing HVAC, parking lot repairs or unpermitted work reduce value, usually by more than the repair cost because buyers add a margin for uncertainty.

Zoning and use

Zoning that allows more density or more uses than the current building can raise value. A use that is legally nonconforming can lower it if it limits rebuilding or expansion.

Flood zone and insurance

In Florida especially, flood zone, elevation, roof age and wind mitigation can change insurance costs enough to move NOI and value. Buyers now get quotes before they commit.

Location, access and visibility still matter most of all, but these are the factors owners can often improve or document before a sale. Our BOV tells you which ones are worth working on.

Valuing property in Florida versus New York

We work in both states, and the same building type can be valued very differently in each. These are the differences that come up most often. Rules and tax rates change, so confirm current details with your attorney and CPA.

IssueFloridaNew York City
Rent regulationState law largely preempts local rent control, so rents are generally set by the lease and the market.Many older multifamily and mixed-use buildings contain rent-stabilized apartments. The 2019 Housing Stability and Tenant Protection Act sharply limited how owners can raise those rents or remove units from stabilization, which changed how buyers value them.
Transfer taxesDocumentary stamp tax on deeds, with a different structure in Miami-Dade County.New York City Real Property Transfer Tax (RPTT) plus New York State transfer tax, with higher rates on larger transactions. Residential purchases above a threshold also face the “mansion tax” paid by the buyer.
InsuranceWind and flood coverage is a major expense and varies with roof age, construction, elevation and flood zone. It can move value significantly.Insurance matters, but it is usually a smaller swing factor than in coastal Florida. Liability and building code compliance drive more of the conversation.
Sales tax on rentFlorida repealed its state sales tax on commercial rent effective October 1, 2024. Confirm with your CPA how it affects your leases.No equivalent sales tax on commercial rent. Manhattan commercial tenants in certain areas may pay the Commercial Rent Tax.
Building recordsCounty property appraiser, building permits and certificates of occupancy from the city or county.ACRIS for deeds and mortgages, DOB for permits, certificates of occupancy and violations, HPD for residential violations and registrations.
Development potentialSite plans, impact fees and local land development codes vary by county and city.Zoning floor area, unused development rights and air rights can be a large part of value, especially in Brooklyn.

Older Florida condominium buildings also face milestone inspection and structural integrity reserve requirements, and Miami-Dade and Broward have long required recertification of older buildings. If your property is a commercial condo or sits in an older building, we ask about those reports early. Foreign sellers in either state should talk to a CPA about FIRPTA withholding before listing.

What to send us for a valuation

We can give a preliminary range from the address alone, but the BOV is only as good as the information behind it. Here is what helps, by property type:

Income property (office, retail, industrial, multifamily, mixed-use)

  • Current rent roll with lease start and end dates, rents, options and deposits.
  • Copies of leases and amendments, or at least the key terms.
  • Operating statements for the trailing 12 months and the prior year.
  • Property tax and insurance bills.
  • Any capital work in the last five years, with permits.
  • For New York buildings with apartments: rent stabilization status and registration history.

Owner-user buildings

  • Building size, year built, construction type and site size.
  • Roof, HVAC and electrical age, and any recent upgrades.
  • How you use the space (office, warehouse, shop, clinic) and any specialized improvements.
  • Whether you would stay as a tenant after a sale.

Land

  • Parcel numbers, survey, zoning, utilities and any prior site plans or environmental reports.

Send it to us through the contact page or call 239-256-5005. We keep your numbers confidential.

How we deliver the BOV

After we receive your information and walk the property, we prepare a written BOV. It includes:

  1. Property summary: location, building, site, zoning and tenancy.
  2. Income analysis: our rebuilt NOI and the cap rate range we believe buyers will apply, for income property.
  3. Comparable sales and active competition: what has sold, what is listed, and how your property stacks up.
  4. Cost and improvement notes: estimated work a buyer will price in, from our construction experience.
  5. Value range and recommended pricing strategy: a range, not a single number, with an explanation of what would move you toward the top or bottom of it.
  6. Likely buyer pool and marketing plan: who we expect to pay the most, and how we would reach them.

We then review it with you by phone or in person. The BOV carries no obligation to list. If you decide to hold, it is still useful for refinancing conversations, partnership planning or a future sale.

Two hypothetical valuations

These examples are hypothetical and do not describe real clients or properties.

Hypothetical income property: a Brooklyn mixed-use building

Picture a four-story building with a ground-floor store and apartments above, some of them rent-stabilized. The commercial lease expires in two years. We would value the residential income under current stabilization rules, without assuming increases the 2019 law no longer allows, and treat the store as a lease-up opportunity at market rent with a cost and time allowance for a new tenant. We would check the certificate of occupancy, open DOB and HPD violations, and whether the lot has unused zoning floor area. If it does, a developer or a buyer planning an enlargement could become the top bidder, and we would test that value alongside the income value.

Hypothetical owner-user building: a Fort Myers flex building

Picture a single-tenant flex building with office in front and warehouse with roll-up doors in back, occupied by the owner’s contracting business. There is no rent roll, so we would compare it to recent sales of similar flex buildings, estimate the market rent a tenant would pay, and check replacement cost against current construction costs in Lee County. Roof age, wind mitigation and flood zone would drive the insurance conversation. If the owner wanted to stay, we would also price a sale-leaseback, where the rent the owner agrees to pay largely sets what an investor will offer.

From a value to a sale

A BOV is often the first step toward listing. When you are ready, our seller pages explain how we run the sale in each market: selling commercial property in Southwest Florida, selling in Brooklyn, selling in Miami and selling in Fort Lauderdale. If you are selling to buy again, see our 1031 exchange advisory and investment sales pages.

Frequently Asked Questions

How do you value commercial property?

Most commercial property is valued with three approaches: the income approach (net operating income and the cap rate buyers apply), the sales comparison approach (recent sales of similar property) and the cost approach (what it would cost to build today, plus land). The weight given to each depends on the property type and who is likely to buy it.

What is my commercial building worth?

It depends on its income, lease terms, condition, location, zoning and the buyers active in your market. Send us the address and, for income property, the rent roll and operating statements, and we will prepare a written broker opinion of value with a range and the reasoning behind it.

What is a broker opinion of value?

A broker opinion of value (BOV) is a written estimate from a licensed real estate broker of what a property should sell for in the current market, with the evidence, likely buyer pool and a pricing strategy. It is not an appraisal and is not used for lending.

Is a broker opinion of value the same as an appraisal?

No. An appraisal is prepared by a state-certified appraiser under formal standards and is what lenders, courts and estates rely on. A BOV is a market-based pricing opinion from a broker, mainly used to decide whether and how to sell.

When do I need a commercial appraisal instead of a BOV?

You generally need an appraisal for a bank loan, estate settlement, divorce, litigation, a property tax appeal, or a partner buyout where the agreement calls for one. For deciding whether to sell and at what price, a BOV is usually the right tool.

What is a cap rate, and why does it matter for my value?

A cap rate expresses the relationship between a property’s net operating income and its price. Lower cap rates mean higher prices for the same income. Cap rates vary with interest rates, tenant quality, lease length, building condition and location, so we set the range for your property from recent sales and buyer feedback rather than a published average.

Does a Florida flood zone affect commercial property value?

It can. Flood zone, elevation, roof age and wind mitigation all affect insurance cost and insurability, which affects net operating income and buyer demand. FEMA’s 50 percent substantial improvement rule can also limit renovation plans for buildings below base flood elevation; confirm with the local building department.

How do rent-stabilized units affect the value of a Brooklyn building?

Buyers value rent-stabilized apartments on their regulated rents, and since the 2019 rent law changes, they assume limited ability to raise rents or deregulate units. That usually lowers value compared with free-market units. We value the stabilized income as it is under current rules and confirm status through registration history.

Does asking for a valuation commit me to listing my property?

No. Our BOV carries no obligation to list with us, and if you hold, it is still useful for refinancing or partner discussions. Contact us through the contact page or call 239-256-5005 to talk about your property.

How long does it take to get a broker opinion of value?

It depends on the property and how soon we receive the rent roll, operating statements and access for a walkthrough. A single-tenant building with complete records is faster than a multi-tenant center or a development site that needs zoning research. We give you a timeline when we start.
