There is a common assumption in net lease real estate that once a deal is under contract, the hard part is over. The asset is “sold,” the buyer is in place, and the path to closing is just a matter of paperwork and timing. Anyone who has spent time in investment sales knows that assumption is not just optimistic, it is often wrong.
Some of the most “perfect” deals on paper never make it to closing. Not because of pricing disagreements or sudden market shifts, but because of issues that only become visible once the purchase and sale agreement is signed and real diligence begins.
This is one of those situations.
The asset itself checked every box that typically attracts capital. It was a net lease retail property with a national tenant, structured under a long-term lease, and located in a strong trade area with stable demographics. On the surface, it looked like a clean execution. Strong credit, predictable income, and a straightforward underwriting story.
That is exactly why it moved quickly into PSA.
Where the Deal Looked “Perfect”
At the marketing stage, everything aligned in a way that felt efficient. The tenant had recognizable brand value, the lease was structured as a net lease, and the rent roll supported the pricing expectations of both seller and buyer. The buyer pool was competitive, and there was immediate alignment on valuation.
In net lease, that combination usually signals a smooth transaction ahead. The assumption is that if credit is strong and the lease is long, most of the risk is already accounted for.
That assumption is what created the first blind spot.
The First Friction Point: Lease Language
Once the PSA was executed and formal due diligence began, the lease document became the focal point of scrutiny.
On the surface, it was a standard structure. But buried within the lease were clauses that materially changed the way risk needed to be underwritten. Certain renewal provisions were less favorable than initially assumed. In addition, there were ambiguities around expense responsibilities that required clarification from both legal counsel and tenant representatives.
Individually, none of these issues were catastrophic. Collectively, they changed the risk profile enough to trigger deeper lender review and revised underwriting assumptions.
This is where many “perfect” deals begin to break down. The assumptions that support pricing at the LOI stage do not always survive legal interpretation.
The Second Issue: Lender Reassessment
Once lease concerns surfaced, the lender began revisiting the original underwriting.
Debt markets today are far more sensitive to structural risk than they were in previous cycles. Even when a tenant is creditworthy, lenders are increasingly focused on lease certainty, rent stability, and downside scenarios.
What initially qualified for standard financing terms began to shift into a more cautious underwriting category. Loan proceeds were adjusted. Debt service coverage assumptions were tightened. Exit cap rates were increased in sensitivity models.
From the buyer’s perspective, the deal was no longer as simple as originally modeled. From the lender’s perspective, additional risk had been identified that required pricing adjustment.
That shift created friction between equity expectations and debt reality.
The Third Break Point: Tenant-Level Clarification
As diligence continued, additional questions arose around tenant-level performance data.
While the tenant brand itself remained strong, store-level performance metrics introduced nuance that was not fully captured in initial underwriting. Sales assumptions, location-specific performance trends, and market competition all became part of the conversation.
This is a critical point that often gets overlooked in net lease investing. Corporate credit does not always equal location-level strength. A tenant can be financially stable while still underperforming in a specific submarket.
That distinction began to matter more as underwriting progressed.
The Moment Deals Start to Shift
By this stage, the deal had not failed. But it had changed.
The buyer’s underwriting model no longer matched the original pricing thesis. The lender’s revised terms impacted returns. Legal review introduced additional complexity. Each adjustment individually was manageable. Together, they created a compounding effect.
This is typically where net lease transactions either retrade or collapse.
In this case, the buyer attempted to re-underwrite the asset at a revised basis that reflected the new risk profile. The seller, however, had anchored expectations to the original pricing agreement. That gap created a structural impasse.
Why Deals Like This Actually Fail
When deals fall apart at this stage, it is rarely because of a single issue. It is usually because early-stage assumptions were too simplified.
Net lease assets are often marketed as stable and predictable. That narrative is not wrong, but it is incomplete. Stability exists, but it is conditional on lease interpretation, tenant behavior, and financing alignment all holding together under scrutiny.
When any one of those pillars shifts, the entire structure has to be reassessed.
In this case, the breakdown was not dramatic. There was no sudden market shock or external event. It was a gradual realization that the asset was slightly more complex than the original pricing narrative suggested.
What This Teaches About Underwriting Discipline
The most important takeaway from deals like this is not that something went wrong. It is that assumptions matter more than appearance.
At the LOI stage, many deals are evaluated on headline terms: tenant credit, cap rate, lease length. But those are only starting points. True underwriting begins when those assumptions are tested against legal documents, lender requirements, and tenant-level data.
That is where real risk is either confirmed or revealed.
The difference between a deal closing and a deal falling apart is often not pricing. It is whether the structure survives that second layer of diligence.
The Reality of “Perfect” Deals
There is no such thing as a perfect retail deal. There are only deals that have not yet been fully tested.
The most dangerous assumption in net lease investing is that simplicity at the surface equals certainty underneath. In reality, simplicity is often just the first layer of complexity.
When a deal moves from marketing to PSA, it stops being theoretical. Every clause, every assumption, and every underwriting shortcut is put under pressure.
Some deals survive that process. Others do not.
The ones that do survive are rarely perfect. They are simply structured well enough, underwritten carefully enough, and aligned strongly enough between buyer, seller, and lender to withstand scrutiny.
That is the real dividing line in net lease investing.
