How Buyer Reps Value a Commercial Property Before Making an Offer

Your client found a property they like. Before you write an offer, you need to answer two questions: does the asking price hold up, and what should your client actually pay?

The asking price is the seller’s opening position. Your valuation is your client’s. This guide covers six methods for valuing commercial real estate, how to apply each one from the buy side, and how to turn the results into an offer range.

Why valuation is the buyer rep’s job

An appraiser will value the property eventually, but usually after your client is under contract and the price is set. Your valuation does three things earlier in the deal:

• It keeps your client from overpaying. A property that fits your client’s strategy can still be priced above what its income supports.
• It sets your negotiating position. A price backed by closed comps and verified income is harder for the listing broker to dismiss than a number that just feels high.
• It predicts the lender’s appraisal. Lenders typically size the loan from the lower of the purchase price and the appraised value. If the appraisal comes in under the contract price, the loan shrinks, and your client either covers the gap in cash or renegotiates.

What drives value for your buyer

A property’s value to your client depends on how well it fits their plan. Four factors shape it:

• Desire: how much the property appeals to buyers in this market, driven by location, tenant mix, and income potential.
• Utility: how well the property serves your client’s strategy. A well-located retail center is worth less to a buyer who needs stabilized income if half the suites are vacant.
• Scarcity: how many similar properties are available. Fewer options mean more competition and less room to negotiate.
• Effective purchasing power: your client’s financing capacity, and that of the buyers bidding against them. In a competitive deal, a buyer with certain financing can sometimes win at a lower price than one with contingencies.

6 ways to value a commercial property from the buy side

Use at least two methods on every deal. When they disagree, the gap tells you where to dig.

1. Sales comparison approach

Pulling comps means looking at recent sales of similar properties in the same market or submarket. For a buyer rep, the key word is sales. Asking prices show what sellers hope to get. Closed sales show what buyers paid.

How to use it: Find three to five closed sales, as recent as the market allows. Adjust for differences in size, age, class, condition, and occupancy. The adjusted range becomes the backbone of your offer.

2. Cost approach

The cost approach estimates what it would cost to build the property today: land value plus construction costs, minus depreciation for physical wear, outdated design, and outside factors such as a weakening neighborhood. It’s most useful for newer or specialized properties with few comps.

How to use it: Treat it as a ceiling check. If the asking price is well above the cost of buying land and building something comparable, the seller needs a strong reason.

3. Income capitalization approach

This method values a property based on its net operating income (NOI) relative to market cap rates. If retail properties in Nashville trade at a 5.5% cap rate and a property generates $77,000 in annual NOI, it’s worth about $1.4 million ($77,000 / 5.5%).

How to use it: Don’t take the NOI in the offering memorandum at face value. Rebuild it from the trailing 12 months of operating statements (T12) and the current rent roll. Small NOI differences move value fast: if actual NOI is $70,000 instead of $77,000, value at the same 5.5% cap rate drops to about $1.27 million, a $127,000 gap.

4. Cost per rentable square foot

Divide the asking price by rentable square footage, which is total square footage minus common areas. A $5 million building with 25,000 SF total and 4,000 SF of common area has 21,000 rentable SF, or about $238 per rentable SF.

How to use it: Compare that figure to market rents to see whether the income the space can produce supports the price, and to the price per rentable SF of your closed comps.

5. Cost per door

For multifamily, divide the price by the number of units. A 40-unit building listed at $8 million costs $200,000 per door.

How to use it: Use it as a fast screen across apartment deals. It ignores unit size and mix, so a building of studios and a building of three-bedrooms can share a per-door price and be very different deals.

6. Gross rent multiplier

Gross rent multiplier (GRM) is the price divided by gross annual rent. A property listed at $6 million that produces $400,000 in gross rent has a GRM of 15. All else equal, a lower GRM means more rent for each dollar of price.

How to use it: Screen deals before you spend time on diligence. GRM ignores operating expenses, so two properties with the same GRM can have very different NOI.

How to pressure-test the offering memorandum

The OM is a marketing document prepared for the seller. Check these assumptions before you build an offer around it:

• Vacancy and credit loss: Does the pro forma assume lower vacancy than the property’s history or the submarket?
• Operating expenses: Do expenses match the T12? Look for missing management fees, missing reserves, and property taxes that will be reassessed after the sale.
• Rent growth: Do recent leases in the submarket support the projected increases?
• Lease rollover: Which leases expire in the next few years, and are those tenants paying above or below market?
• Deferred maintenance: Roofs, HVAC, parking lots, and other capital items reduce what your client should pay.

How to build the offer range

Bring the methods together into three numbers:

• Opening offer: the low end of what your comps and rebuilt NOI can defend.
• Target price: where the methods cluster.
• Walkaway price: the most your client should pay, based on verified income and the high end of adjusted comps.

Write down the reasoning behind each number. When the listing broker pushes back, you’ll answer with closed sales and actual NOI.

The bottom line

The asking price is where the seller starts. Your valuation, built on closed comps and verified income, is where your client starts. Bring both to the table and you negotiate from evidence.
