A polished offering memorandum can make two net lease properties appear nearly identical: the same asking price range, a recognizable tenant, and a long stated lease term. The difference often sits in the details behind those headlines. An investment memorandum review is where a buyer determines whether projected income, tenant strength, lease protections, and future resale prospects support the price being requested.
For a single-tenant NNN acquisition, the memorandum is a starting point, not proof. It is designed to present the opportunity favorably and may rely on assumptions that require confirmation. A disciplined review helps investors separate the property’s current economics from the marketing narrative before time, deposits, and 1031 exchange deadlines create unnecessary pressure.
What an Investment Memorandum Can and Cannot Confirm
An investment memorandum usually provides the information needed to screen an opportunity: tenant name, rent, lease expiration, asking price, cap rate, building size, site information, and a summary of lease responsibilities. It may also include tenant financial information, market demographics, sales data, or commentary on comparable transactions.
That information is useful, particularly when investors are evaluating several properties at once. But the memorandum rarely answers every question that affects value. A stated 12 years of remaining lease term, for example, does not reveal whether the tenant has early termination rights, whether the parent company guarantees the lease, or whether significant landlord capital obligations arise before expiration.
Treat every material statement as a point to verify. The right standard is not whether the memorandum is accurate in a general sense. The standard is whether the underlying documents support the income stream you are buying.
Start With the Investment Thesis
Before reviewing lease language or demographic charts, define why the property belongs in the portfolio. For many net lease investors, the thesis is simple: preserve capital while generating predictable income from a creditworthy tenant on a long-term lease. Even so, each component needs to be tested.
Consider the relationship between the tenant, the real estate, and the lease term. A nationally known tenant may be attractive, but brand recognition alone does not establish unit-level performance or guarantor strength. A newer building in a strong retail corridor may support future liquidity, yet a short remaining term could limit the buyer pool at resale.
The property should make sense under more than one future scenario. Ask whether you would still want to own the real estate if the tenant did not renew. This question is especially important for special-purpose buildings, locations with limited alternative use, and assets where the building cost is high relative to underlying land value.
Read the Lease as the Economic Engine
In a single-tenant investment, the lease often matters as much as the building. The memorandum may call an asset “absolute NNN” or “triple net,” but those labels should be confirmed against the executed lease and any amendments.
Begin with the rent schedule. Confirm current base rent, the date of the next increase, the size and structure of future increases, and whether rent steps are fixed or tied to an index. Small differences compound over a long holding period, and a lease with flat rent for many years may trade differently from one with regular contractual growth.
Next, evaluate expense responsibility. In a true net lease, the tenant may be responsible for real estate taxes, insurance, maintenance, repairs, and capital expenditures. Yet exceptions are common. Roof, structure, parking lot, HVAC, environmental conditions, and compliance-related work can remain the landlord’s responsibility, either in full or above a stated threshold.
The remaining lease term requires equal attention. A long stated term is valuable only if it is firm. Review renewal options, termination rights, co-tenancy provisions where applicable, assignment rights, purchase options, and any rights that could affect continuity of income. If a tenant can terminate after a defined event, the nominal lease term may overstate the actual duration of the cash flow.
Finally, identify the actual obligor. Is the lease guaranteed by a public parent, a large operating entity, a franchisee, or a local affiliate? The difference can materially affect credit analysis and resale liquidity. Tenant credit is not static, so buyers should understand both the current financial profile and the nature of the guaranty.
Test Memorandum Claims Against Source Documents
A careful investment memorandum review moves from summary materials to documentation. The lease, amendments, estoppel certificate, title materials, survey, environmental reports, property tax information, and operating history each answer a different question.
The lease and amendments establish the contractual economics. An estoppel certificate, when available, can confirm rent, lease status, security deposits, defaults, and disputes directly from the tenant. Title and survey work identify access, easements, encroachments, and restrictions that may affect operations or future redevelopment.
Property tax review is also essential. Taxes can change after a sale or reassessment, even when the tenant is responsible for payment. The buyer should understand how the lease treats tax increases, appeals, and any caps on recoverable expenses. Similarly, environmental reports should be evaluated in light of the property’s historic and current use, rather than treated as a routine box to check.
When information conflicts, do not assume the more favorable figure is correct. A difference between the memorandum’s rent schedule and an amendment, or between a site plan and survey, needs resolution before the transaction progresses. Clear documentation protects both underwriting discipline and closing certainty.
Price Risk, Not Just Yield
The advertised cap rate is a useful comparison point, but it is not a complete measure of value. Two properties with the same cap rate can carry very different risk profiles based on lease term, rent growth, tenant credit, location, building utility, and residual value.
A buyer should consider the likely market for the asset several years from now. Properties with strong sites, broadly useful improvements, and durable tenant demand typically offer more exit flexibility than highly specialized assets. Conversely, a higher initial yield may be appropriate when the lease is shorter, the tenant is weaker, or the real estate has limited alternate use.
Financing also deserves attention early. Debt terms can change the effective cash flow, and lenders may view short lease duration, tenant concentration, or specialized property types more conservatively. Investors using leverage should underwrite a range of financing outcomes rather than relying on a preliminary quote.
This is where experience in the net lease market matters. Comparable sales are most meaningful when the underlying lease structures and credit profiles are genuinely similar. A comparable transaction involving a corporate guaranty, 15 years of firm term, and annual rent bumps should not be used casually to justify pricing for a franchisee-guaranteed lease with flat rent and near-term options.
Investment Memorandum Review in a 1031 Exchange
For 1031 exchange buyers, timing can make an otherwise sound review more difficult. The need to identify replacement property within statutory deadlines can lead investors to focus heavily on availability and headline yield. That pressure should not reduce the level of diligence applied to the lease and real estate.
A practical approach is to establish acquisition criteria before the relinquished property closes: preferred tenant credit profile, minimum remaining lease term, desired price range, acceptable property types, and tolerance for landlord responsibilities. This allows an investor to screen replacement options faster without abandoning core underwriting standards.
Exchange planning involves tax and legal considerations outside a broker’s role. Investors should coordinate early with a qualified intermediary and certified CPA regarding exchange requirements, deadlines, and the structure of a proposed transaction. No property should be selected solely because it appears to solve an exchange timeline.
Questions That Should Be Answered Before an Offer
Before submitting an offer or removing contingencies, the buyer should be able to answer several direct questions:
- Who is legally obligated under the lease, and what evidence supports that party’s credit quality?
- What landlord costs remain during the current lease term, including roof, structure, HVAC, parking, and environmental obligations?
- Is the stated lease term firm, or can it be shortened by termination rights, options, or other provisions?
- Does the location retain value and marketability if the present tenant leaves?
- Does the asking price reflect the property’s specific risks, rather than only its published cap rate?
If the answer to one of these questions is uncertain, the issue may not end the transaction. It may call for further documentation, a revised price, different financing assumptions, or a decision to pursue another asset. Good acquisition discipline is not about finding a property with no risk. It is about understanding which risks are being accepted and whether the return is appropriate for them.
Triple Net Investment Group applies this document-first approach to help buyers evaluate net lease opportunities with the perspective gained from nationwide transaction execution. Before committing capital, give the lease, tenant, and real estate enough scrutiny to deserve the confidence you place in the income stream.
