Retail underwriting is how you check whether a shopping center or retail property earns enough to cover its loan payments and still deliver a return. The United States Census Bureau reports that e-commerce accounted for 17.1 percent of total retail sales in the second quarter of 2026, up from 16.3 percent a year earlier, which still leaves close to 83 percent of retail sales placed outside online channels. Retail differs from other kinds of commercial property in one respect above all. The rent a tenant can pay is limited by what that tenant sells, so underwriting retail means underwriting the businesses inside the building as well as the building itself.
A tenant paying rent today at an occupancy cost they cannot sustain is a vacancy with a date on it.
In retail, one lease can take several others with it. Co-tenancy is the clause that turns a single vacancy into a rent roll problem.

Percentage rent is additional rent a retail tenant pays based on a share of its sales, usually once sales pass an agreed level. It sits on top of the base rent. In underwriting it is treated as upside rather than as dependable income, because it disappears the moment sales soften.
A natural breakpoint is the sales level at which percentage rent starts, calculated by dividing the annual base rent by the percentage rate in the lease. A tenant paying $100,000 in base rent under a 5 percent clause reaches its natural breakpoint at $2 million in sales. Some leases set an artificial breakpoint instead, negotiated at a different number, so each lease has to be read rather than assumed.
Occupancy cost ratio is a tenant's total rent and charges expressed as a share of its sales at that location. It is the single best indicator of whether a lease is sustainable. A tenant whose occupancy cost has drifted well above what its category normally carries is unlikely to renew at the current rent, whatever the lease says today.
Sales per square foot is a tenant's annual sales at a location divided by the area it occupies. It allows tenants of very different sizes to be compared, and it feeds directly into occupancy cost. Not every lease requires a tenant to report it, which is why some rent rolls carry more certainty than others.
An anchor tenant is the large tenant that draws shoppers to a center, typically a grocery store, department store or big-box retailer. Its presence supports the rent every smaller tenant pays. Because so much depends on it, the anchor's lease term, rent level and renewal options matter more in underwriting than any other single document in the file.
A co-tenancy clause gives a tenant the right to reduce its rent or end its lease if the anchor, or a stated number of other tenants, leaves the center. It exists to protect tenants who signed on the strength of the foot traffic. In underwriting it is what turns one departure into several, and it is the reason an anchor vacancy has to be modeled across the whole rent roll.
A shadow anchor is a large retailer that draws traffic to a location but sits on land the owner does not control, usually next door or across the parking lot. The center benefits from the traffic while having no say in whether that retailer stays. Underwriting has to treat that benefit as borrowed rather than owned.
A kick-out clause lets a tenant terminate its lease early if its sales at that location fail to reach an agreed level by a certain date. It is a common concession for retailers taking a chance on an unproven location. In underwriting it puts an earlier possible end date on a lease than the expiry shown in the rent roll.
CAM stands for common area maintenance. CAM charges are what tenants reimburse toward the cost of running the shared parts of a center, such as parking lots, lighting, landscaping, security and snow removal. Each tenant pays a share, but caps, exclusions and separately negotiated formulas mean the total collected is usually less than the total spent.
An outparcel is a separate parcel of land at the edge of a shopping center, usually along the road frontage, occupied by a freestanding building such as a bank, restaurant or pharmacy. Outparcels often carry their own leases and can be sold separately from the center, so they are valued on their own terms rather than folded into the main asset.
A credit tenant lease is a lease where the tenant is a company with a strong, publicly rated balance sheet. The rent is underwritten much like a bond payment, because the certainty comes from the tenant's credit rather than from the property's location or trading performance. It is common in single tenant net lease retail, and it shifts the analysis from real estate toward corporate credit.
Gross leasable area, usually shortened to GLA, is the total floor area in a center that can be leased to tenants, excluding common areas like corridors and parking. Retail centers are sized and compared in GLA, and it is the denominator behind sales per square foot and most recovery formulas, so two centers described as the same size can differ if one is measuring GLA and the other total built area.
A trade area is the geographic area a center actually draws its customers from, defined by drive time or distance rather than by administrative boundaries. It is what determines how many households a tenant can realistically reach, and how much of that demand is already served by competing centers. Trade area analysis is the work of measuring it, and it is the difference between a rent that looks supportable on paper and one the local population can sustain.
A power center is a large open-air retail format made up mostly of big-box stores, often with few small inline tenants. Because a handful of leases carry the whole income, and because very few tenants can take over a vacated big box, a single departure has a much larger effect here than in a center with many smaller tenants.
| Metric | What it measures | Why it matters |
|---|---|---|
| Net operating income | Income left after operating costs, before loan payments | The starting point for value and for how much you can borrow |
| Gross leasable area | Total floor area that can be leased to tenants | The unit centers are sized and compared in, and the denominator behind sales per square foot |
| Sales per square foot | Tenant sales divided by the area occupied | Compares tenants of different sizes and feeds occupancy cost |
| Occupancy cost ratio | Rent and charges as a share of tenant sales | The clearest signal of whether a lease is sustainable |
| Percentage rent | Additional rent owed once sales pass the breakpoint | Upside rather than base income; it goes first when sales soften |
| Recovery ratio | Share of operating costs tenants actually reimburse | Caps, exclusions and vacant space all reduce what gets collected |
| Anchor lease term remaining | Years left on the anchor's commitment | Sets the clock on the center's biggest single risk |
| Weighted average lease term | Average time left on the leases, weighted by rent | How long the income is contracted before you are re-leasing |
| Releasing cost per square foot | Fit-out, commissions and free rent to sign a replacement | Backfilling a big box costs far more than an inline unit |
| DSCR | Income against annual loan payments | Sets how large a loan the property can support |
| Debt yield | Income against loan amount | How a lender sizes a loan without relying on interest rates |
| Going-in cap rate | Income against purchase price | Whether the price makes sense for the format and the trade area |
| Exit cap rate | Assumed income against assumed sale price | Often the single biggest factor in the projected return |
Six rows on this table link to the shared glossary rather than being defined here, covering five terms, because cap rate occupies two rows: weighted average lease term, recovery ratio, DSCR, debt yield, and cap rate as both going-in and exit. All five are cross-asset terms, defined once for the whole site rather than repeated on each property-type page.
In underwriting, percentage rent is treated as upside and never as base income. The lease sets a percentage of sales and a breakpoint, and once the tenant's sales pass that level the tenant pays a share of everything above it. The reason it stays out of the base case is that it is the first income to disappear when sales weaken, which is exactly when the rest of the model is under pressure too.
In underwriting, the anchor is the lease that supports every other lease in the center. It brings the foot traffic that inline tenants signed up for, which means its term, its rent and its renewal options set the risk profile for the whole asset. The anchor's lease is also what activates the co-tenancy clauses elsewhere in the rent roll, so a single anchor decision can reprice or release several other tenants at once.
In underwriting, a co-tenancy clause is what stops a vacancy from being contained. It gives a tenant the right to cut its rent or leave if the anchor, or a stated number of other tenants, goes dark. Every lease in the center has to be checked for one, because the cost of an anchor departure is not the anchor's rent. It is the anchor's rent plus everything the clauses allow other tenants to claw back.
CAM charges are what tenants reimburse toward running the shared areas of a center. In underwriting, the calculation matters less than the exceptions. A tenant's share is usually based on its area as a proportion of the center, but anchors frequently negotiate their own formula, caps limit how fast a tenant's contribution can rise, and certain costs get excluded entirely. Vacant space reimburses nothing at all, so the owner carries that portion. The annual CAM reconciliation is where this gets settled: tenants pay estimated charges through the year, and the reconciliation trues those estimates up against what was actually spent. It is also where the caps and exclusions bite, because a capped tenant simply does not absorb the overage. Underwriting to the lease formulas rather than to a simple pro-rata split is what makes the recovery number real.
An outparcel is a separate parcel at the edge of a shopping center, usually with road frontage and a freestanding building on it such as a bank, drive-through restaurant or pharmacy. In underwriting it is treated as its own asset. Outparcels carry separate leases, often to stronger credit tenants, and they can be sold independently of the center, which sometimes makes them the most valuable part of a deal per square foot.
In underwriting, a credit tenant lease moves the analysis from property to corporate credit. Because the tenant carries a public rating and the lease is typically long and net, the income behaves much like a bond coupon, and the value tracks the tenant's creditworthiness and the remaining term. The real estate question does not disappear. It resurfaces at expiry, when the building has to stand on its location and its alternative uses rather than on the covenant.
Valuation starts with the income the center collects after real recoveries, capitalized at a rate that reflects the format, the trade area and the strength of the tenant roster. Three checks sit alongside it. Trade area analysis establishes how many households the center can actually draw on by drive time, and how much of that demand competing centers already take, which is what tells you whether current rents have local support. Tenant occupancy costs get reviewed, because rents above what tenants can sustain will not survive renewal. And the anchor position gets tested, since a center whose traffic driver is leaving or sits on land the owner does not control carries risk the current income does not show.
Underwriting in retail is the process of verifying what a center collects, checking whether each tenant's sales can sustain the rent it pays, reading the anchor and co-tenancy provisions to understand how one departure spreads, rebuilding recoveries at what tenants genuinely reimburse, and testing whether the resulting income supports the loan and the return. It differs from other commercial property types because the rent is limited by the tenants' trading performance, so the businesses inside the building get underwritten alongside the building.
To underwrite a retail property, start by pulling every lease and building a tenant roster that shows rent, charges, expiry dates and any early termination rights. Collect reported sales and work out each tenant's occupancy cost, because a rent the tenant's sales cannot sustain will not survive renewal regardless of what the lease says today. Read the anchor lease and every co-tenancy clause, then model what happens to the rest of the rent roll if the anchor leaves. Rebuild recoveries at what tenants actually reimburse once caps, exclusions and vacant space are accounted for. The deal works if that income covers debt service at your target DSCR and still clears your return threshold once the cost of backfilling space is funded.
