Buying and Selling Commercial Properties as Investments

Investment Sales & Acquisitions 101

Investment sales is the discipline of commercial real estate that focuses on buying and selling income-producing properties as financial assets. The analysis is part real estate, part finance—and the difference between a well-structured deal and an expensive mistake usually comes down to underwriting discipline.

01

What Is Commercial Investment Sales?

Investment sales refers to transactions where the primary motivation is the income stream (or potential income stream) a property generates, not the buyer's own operational use of the space. The buyer is acquiring a stream of cash flows and the asset underlying them—not square footage they plan to occupy.

The sector includes all major commercial asset types: retail, multifamily, office, industrial, self-storage, hospitality, and specialty properties. Within investment sales, transactions are broadly categorized as core (stable, fully leased properties with strong credit tenants), core-plus (similar but with some near-term leasing or operational risk), value-add (properties requiring repositioning, renovation, or lease-up), and opportunistic (highest risk, typically distressed or development-stage).

Private investors dominate the sub-$10M segment in most Midwest markets. Institutional buyers (insurance companies, REITs, private equity funds) are active above $20–30M in most cases. Between those thresholds—the $5M–$25M range—regional syndicates, family offices, and experienced private operators are the most active buyers.

Core Financial Metrics

Investment sales transactions are analyzed through a set of standard metrics. Fluency in these terms is required for any productive conversation with a broker, seller, or lender.

  • Cap rate (capitalization rate): NOI divided by price. Measures the unlevered yield at a single point in time. A 6.5% cap rate means a buyer pays $1 for every $0.065 in annual NOI.
  • NOI (Net Operating Income): Gross income minus vacancy allowance minus operating expenses. Does not include debt service.
  • Cash-on-cash return: Annual pre-tax cash flow after debt service divided by total equity invested. Reflects the levered return on equity.
  • IRR (Internal Rate of Return): Discount rate that makes the net present value of all cash flows (including sale proceeds) equal to zero. The primary benchmark for institutional investment decisions.
  • Equity multiple: Total cash returned to investor divided by total equity invested. A 2.0x equity multiple means the investor doubled their money.
  • Going-in cap rate vs. exit cap rate: The cap rate at acquisition vs. the assumed cap rate at disposition. The spread between them—expanding or compressing—drives a significant portion of value creation or destruction in a hold.
03

Key Terms to Know

  • LOI (Letter of Intent): Non-binding document outlining the key terms of a proposed transaction—price, earnest money, due diligence period, closing timeline. Sets the framework before a formal purchase agreement is drafted.
  • Due diligence period: The contractual window (typically 30–60 days in commercial transactions) during which the buyer investigates the property. Physical inspection, lease review, financial audit, environmental assessment, and title review occur here.
  • Earnest money: Good-faith deposit made by the buyer at contract execution. May become non-refundable after due diligence is waived. Amount and hard/soft terms are negotiating points.
  • 1031 exchange: IRS provision allowing the deferral of capital gains taxes when proceeds from a sale are reinvested in a like-kind property within defined time windows (45-day identification / 180-day close).
  • Sale-leaseback: Transaction where the property owner sells the building and simultaneously leases it back as a tenant. Common in corporate real estate; frees capital while retaining operational use.
  • Off-market: Property sold without public listing. Seller values discretion or speed; buyer gains access through broker relationships before the broader market can bid.

Evaluating an Investment Property

Sound underwriting starts with verifiable numbers and ends with conservative assumptions about what you can't control. The offering memorandum is a marketing document; it presents the property in the best possible light. Verify every assumption independently.

Stress-test the NOI before pricing in any upside. What is the property worth at current rents, current expenses, with a 90-day vacancy reserve? That's the floor. The value-add upside, if any, should be modeled separately and discounted for execution risk.

Cap rate comparison is useful context but not the underwriting itself. Two properties with the same cap rate may have very different risk profiles based on lease term, tenant credit, CapEx needs, and market liquidity.

  • Build your own operating statement from source documents—don't rely on the seller's pro forma
  • Verify tax assessments and insurance costs independently; both are commonly presented at below-actual levels
  • Model at least three scenarios: base case, downside (rents flat, higher vacancy), and upside
  • Account for financing costs explicitly—a 6.0% cap rate property financed at 7.25% is cash flow negative from day one without other income
  • Understand the exit: who is the buyer for this asset in 5 years, at what cap rate, and what market conditions underpin that assumption
05

Common Mistakes

Anchoring on the seller's pro forma rather than current verified cash flows is the root cause of most acquisition mistakes. A property's actual NOI at the time of purchase is knowable; projected NOI requires assumptions. Keep them distinct.

Buying on cap rate alone without stress-testing the lease term is a recurring error. A 7% cap rate on a property with a 6-month lease remaining is not a stable yield—it's an upfront payment for execution risk.

1031 exchange pressure can override analytical discipline. Buyers with a 45-day identification deadline sometimes make commitments they wouldn't make otherwise. The tax tail should not wag the investment dog.

  • Underestimating closing costs, financing costs, and holding costs during any renovation or lease-up period
  • Failing to fully underwrite the tenant—financial statements, sales history where available, guarantor creditworthiness
  • Ignoring market liquidity for the exit: small markets may have limited buyer pools for certain asset types
  • Assuming a straight-line relationship between NOI growth and value creation when cap rate changes can dwarf operational improvements

Market Conditions (2024–2025)

The Federal Reserve's rate cycle materially compressed investment sales transaction volume from 2022 to mid-2024. CBRE tracked a roughly 40–60% decline in commercial transaction volume from 2021 peak levels depending on asset type. As rate expectations shifted in late 2024, deal flow began to recover—slowly and unevenly by sector.

Industrial and multifamily maintained the deepest buyer pools throughout the slowdown. Office saw the most severe contraction, with many assets effectively removed from the investable universe for institutional capital. Retail—particularly necessity-anchored—held its position better than most expected.

In Indiana and Kentucky, private buyer activity in the $1M–$10M range remained more consistent than institutional market data suggests. These markets have a strong base of local and regional investors who are not as rate-sensitive as leveraged institutional buyers. Off-market activity has been elevated as sellers seeking speed and certainty found willing buyers at the right price.

Working With an Investment Sales Broker

An investment sales broker serves both sides of a transaction at different times—but not simultaneously. On the sell side, the broker's job is accurate pricing, qualified buyer sourcing, and process discipline. On the buy side, it's identifying what's available (including off-market), providing market context, and helping with due diligence coordination.

The broker's value is not the listing—it's the relationships and market knowledge that make the listing or acquisition successful. A broker who can deliver a qualified buyer to a seller's doorstep before the property hits LoopNet provides real economic value. That value is what separates brokers who compete on fees from brokers who compete on results.
