The quick read: lenders underwrite tenant rollover by mapping every lease expiration against the loan term, haircutting income from leases that could leave, deducting the tenant improvement and leasing commission (TI/LC) cost of replacing them, and sizing the loan on what remains. Where too much rent expires inside the term, they add a reserve, a cash sweep or lower proceeds.
This page covers the rollover mechanics only. For the loan structures, lender channels and what drives the rate on a multi-tenant building, read the sibling guide on how multi-tenant commercial properties are financed.
Property: multi-tenant office, retail, flex or light industrial Core risk: leases that expire before the loan matures What lenders measure: expirations by year, weighted average lease term, re-leasing cost and downtime Where it shows up: underwritten cash flow, debt yield, DSCR and loan structure Worked example below: an illustrative rent roll, not a real deal
Why does tenant rollover matter more to a lender than today's occupancy?
Tenant rollover matters more to a lender than today's occupancy because the lender is repaid from rent collected over the whole loan term, and a building that is fully leased today can lose half its income before maturity if the wrong leases expire. The lease-expiration schedule, not the occupancy line, is what the lender underwrites.
Bank examiners are told to look at the same thing. The Office of the Comptroller of the Currency's Commercial Real Estate Lending booklet (Version 2.0, March 2022) lists "Lease renewal trends and anticipated rents" and "Terms of current leases" among the factors an analysis of a property's income-generating capacity typically considers. The FDIC's commercial real estate examination module (dated 05/24) tells examiners to "Assess the accuracy of rent-roll income by comparing reported levels to rental income reflected in tax returns or terms of individual leases."
So the rent roll and the leases behind it are the first documents a lender reads. Three things on them move the loan: when each lease ends, how much of the rent it carries, and what it will cost to keep or replace that tenant.
How do lenders compare weighted average lease term with the loan term?
Lenders compare weighted average lease term, or WALT, with the loan term to see whether the average dollar of rent is contracted to outlast the loan. A WALT shorter than the term means much of the rent roll must renew or re-lease before maturity, so the lender underwrites that re-leasing instead of assuming it happens for free.
WALT is each lease's remaining term weighted by its share of rent or of square feet. Lenders usually look at both, because a large low-rent tenant and a small high-rent tenant tell different stories.
WALT is only an average, so lenders also read the expiration schedule year by year. A four-year WALT made of evenly spread expirations is easier to underwrite than the same WALT with most of the rent ending in one year. Concentration is the real risk: one year, one tenant, or one anchor whose departure could hit other leases. The OCC booklet notes that some retail lease clauses "may call for a decrease in rents or permit termination if an anchor tenant ceases operations (co-tenancy clauses)."
Lease length also differs by property type, which is why there is no universal WALT target. The OCC booklet says office "Lease terms are typically for periods of three, five, or seven years"; that for retail "Lease terms typically range from five to 10 years with anchor tenants often signing leases of 20 to 25 years with options to renew"; and that on multi-tenant industrial "Lease terms of three to five years are common." A ten-year loan on a building of three-to-five-year leases will see every tenant roll at least once, and the lender knows it.
How do lenders haircut income from leases that expire during the loan?
Lenders haircut income from expiring leases by assigning each one a renewal probability and a period of downtime if the tenant leaves, then reducing underwritten rent by the expected vacancy. Some also mark expiring rents to market, so an above-market lease is underwritten at a replacement tenant's rent.
The OCC booklet describes the method directly: "The re-leasing costs can be projected by analyzing the rent roll and using an assumption about the probability of renewals." The inputs a lender chooses are these.
Renewal probability: the share of expiring tenants assumed to stay, set from the tenant's history, the space's fit and the submarket. Downtime: months of lost rent between a tenant leaving and a replacement paying, including free-rent periods. Market rent: the rent a new tenant would sign today, which can sit above or below the expiring rent. Tenant-specific facts: renewal notices already received, termination options, the tenant's own credit, and how much it has invested in its space.
Every one of those is an assumption, and lenders pick them conservatively. A document that replaces an assumption with a fact, such as a signed renewal or a letter of intent, moves the underwriting more than any argument about the market.
How do lenders size TI/LC and rollover reserves?
Lenders size TI/LC and rollover reserves from the re-leasing cost of the expiring leases: tenant improvement allowances to build out or refresh space, plus leasing commissions to the brokers who sign the renewal or replacement. That cost is deducted from underwritten cash flow, collected into a reserve, or both.
On leasing commissions, Appendix D of the OCC booklet, which says its underwriting metrics are for general information and vary by market, describes typical underwriting assumptions: "Leasing commissions are calculated as a percentage of total lease payments with typical underwriting assumptions of 4 percent for new leases and 2 percent for renewals." On tenant improvements it gives no figure, noting only that they "are higher for new tenants than for renewing tenants and can vary widely depending on the market and building class." There is no universal reserve per square foot; the right number depends on the building, the space and the market.
The booklet also explains why the cost can hide: "Re-leasing costs are not always considered as an operating expense in calculating NOI but are an important consideration when analyzing cash flow." A lender that sizes on net cash flow after TI/LC, rather than on net operating income, is pricing rollover in.
The structures lenders use, described by mechanism:
Upfront TI/LC reserve: funded at closing from loan proceeds or sponsor equity, released as leases are signed and space is delivered. Ongoing TI/LC deposits: a monthly amount collected with debt service and held for future leasing. Tenant-specific rollover reserve: built up ahead of one large expiration, often released if that tenant renews. Cash sweep: a trigger, such as a major tenant giving notice or failing to renew by a set date, that traps excess cash flow in a leasing reserve until the space is re-let or enough has been collected. Reduced proceeds: instead of structure, the lender simply lends less.
Trigger definitions, caps and release conditions are negotiated loan by loan. They matter as much as the rate, because a sweep can hold your distributions for months.
How does rollover change DSCR and debt yield on a rent roll?
Rollover changes DSCR and debt yield by shrinking the cash flow the lender sizes on: expected downtime cuts income, and annualized TI/LC cost is deducted before coverage is tested. On a building with heavy rollover inside the term, the loan the property supports can fall well below what in-place income alone suggests.
Illustrative example (not a real deal, not a quote): a 50,000-square-foot multi-tenant building with five tenants, in-place net operating income of $800,000 and a five-year loan term. Every figure below is invented for the arithmetic.
Table 1: Illustrative rent roll and rollover schedule
| Tenant | Square feet | Annual base rent | Lease expires in | Inside a five-year term? |
|---|---|---|---|---|
| A | 15,000 | $300,000 | Year 2 | Yes |
| B | 10,000 | $220,000 | Year 4 | Yes |
| C | 10,000 | $180,000 | Year 7 | No |
| D | 8,000 | $192,000 | Year 1 | Yes |
| E | 7,000 | $140,000 | Year 9 | No |
| Total | 50,000 | $1,032,000 | WALT 4.1 years by rent | 69% of rent expires |
Step 1, WALT: weighted by rent, the leases have 4.1 years left on average, shorter than the five-year term. Tenants A, B and D, carrying 69% of the rent and 66% of the space, expire before maturity.
Step 2, the haircut: assume an illustrative 65% renewal probability and six months of downtime when a tenant leaves. Expected lost rent across the three expirations is $124,600, or about $24,900 a year over the term.
Step 3, TI/LC: leasing commissions use the OCC booklet's typical 4% new and 2% renewal assumptions on a five-year replacement lease at the same rent. Tenant improvements use illustrative allowances of $25 per square foot for a new tenant and $10 for a renewal. Blended at 65% renewal, TI/LC across the three leases totals $599,370, about $119,900 a year.
Step 4, sizing: in-place net operating income of $800,000, less $24,900 of downtime and $119,900 of TI/LC, leaves underwritten net cash flow of about $655,200.
Table 2: Illustrative loan sizing, in-place income versus rollover-adjusted cash flow
| Sizing test (illustrative) | On in-place NOI of $800,000 | On rollover-adjusted cash flow of $655,200 |
|---|---|---|
| 10% debt yield | $8.00 million | $6.55 million |
| 1.25x DSCR at a 7.5% loan constant | $8.53 million | $6.99 million |
| Loan the lower test allows | $8.00 million | $6.55 million |
The rollover costs about $1.45 million of proceeds in this example. A lender willing to lend closer to $8 million would ask for structure instead: an upfront TI/LC reserve, monthly deposits, or a sweep keyed to tenant A, whose lease carries the most rent. Run your own rent roll through the underwriting calculator before a lender runs its version.
How do different lender types treat near-term lease expirations?
Different lender types treat near-term lease expirations differently because they hold risk differently: balance-sheet lenders can re-underwrite at renewal, securitized lenders lock structure in at closing, and bridge lenders lend on the re-leasing plan itself. The same rent roll can draw a reserve from one, a sweep from another and lower proceeds from a third.
Table 3: How lender types typically treat rollover inside the loan term (mechanism only, no universal figures)
| Lender type | Typical response to near-term expirations | What to ask |
|---|---|---|
| Community and regional banks | Lower proceeds or a tenant-specific reserve; shorter terms let the bank re-underwrite at renewal | Is the reserve released on renewal, and is any covenant tied to occupancy? |
| National banks | Sizing on cash flow after re-leasing costs; financial covenants tested during the term | Which covenant, how it is measured, and what cure rights apply |
| Life insurance companies | A preference for lease terms that outlast the loan; heavy rollover inside the term can mean lower leverage or a decline | Would a shorter term or a larger reserve change the answer? |
| CMBS conduit lenders | Net cash flow after TI/LC; upfront and ongoing TI/LC reserves; cash-management triggers such as lease sweeps written into the loan documents | The exact sweep trigger, the cap and the release test |
| Debt funds and bridge lenders | Lending on the re-leasing business plan, with future funding for TI/LC | How future funding is released and what the extension tests require |
The Federal Reserve's July 2026 Senior Loan Officer Opinion Survey reported: "Over the second quarter, moderate and modest net shares of banks reported having eased standards for loans secured by nonfarm nonresidential (NFNR) properties and multifamily properties, respectively." Eased standards for NFNR loans do not mean a lender will ignore a rent roll that expires inside the term.
What should a borrower fix before submitting a property with heavy rollover?
A borrower with heavy rollover should replace assumptions with documents before submitting: signed renewals, letters of intent, tenant estoppels and a realistic re-leasing budget. Every expiration you can prove is handled is one the lender does not have to haircut, and a clean rollover story often wins more proceeds than negotiating the rate.
Rent roll: current, reconciled to the leases and bank deposits, with every expiration, option and termination right listed. Renewal evidence: executed renewals, amendments or letters of intent for the leases expiring inside the term. Re-leasing budget: your own TI, commission and downtime assumptions, supported by recent leasing in the building. Tenant detail: size, credit and history of the largest tenants, and any notices already received. Term choice: a term that ends before a major expiration, or one that runs well past it with a reserve.
How do you get lenders competing on a multi-tenant property with near-term rollover?
You get lenders competing on a multi-tenant property with near-term rollover by sending one complete package, meaning the rent roll, the leases, renewal evidence and your re-leasing budget, to several lender types at once, then comparing the loan each one actually allows after reserves and sweeps, not the headline rate.

The bottom line
Lenders underwrite rollover by comparing lease expirations and WALT with the loan term, haircutting rent that could leave, and deducting TI/LC before testing debt yield and DSCR. Heavy rollover inside the term means a reserve, a cash sweep or a smaller loan. Documented renewals and a realistic re-leasing budget are the strongest answers a borrower can bring.
