Rent Roll in 2026: Gross to Net Income and What a Stabilisation Lender Actually Counts

A rent roll looks like a simple thing: a list of units, the rent each one pays, a total at the bottom. That total is the number owners quote, agents advertise and borrowers put at the top of a finance request. It is also almost never the number a lender sizes debt on. The gap between the rent roll a building shows and the income a lender will actually lend against is where financing decisions are quietly won and lost in 2026, and understanding it is worth more to a borrower than any rate table. This article is a plain walk through what a rent roll really is, how a lender takes it from gross to net, and why the same building can carry two rent rolls at once.

First, the standing and the caveats. Stabilisation Finance is a trading name of Lenzie Consulting Ltd, and we are a broker and introducer rather than a lender: we arrange, we place and we structure the debt against a rent roll, while the lender holds the credit decision and the funds. We are not authorised and regulated by the Financial Conduct Authority (FCA); the lending we arrange on commercial and investment property is unregulated commercial lending, and any regulated element is referred to an appropriately regulated firm. Every figure here is an indicative market band for 2026, not an offer or a quote. The Bank of England base rate is 3.75 percent, held since December 2025, which is the cost of money most of these facilities are ultimately priced against.

What a rent roll actually is

At its simplest a rent roll is a schedule of the income-producing units in a property or portfolio: each unit, the tenant or occupier, the monthly rent, the lease term or tenancy terms, the review dates, and the total contracted rental income. On a multi-unit residential block it lists the flats and their tenancies. On a commercial building it lists the leases, the terms and the breaks. On a portfolio it aggregates the rental income across properties. It is the single most important document in any income-property finance case, and property owners, property managers and lenders all lean on it: it is the raw material for everything a lender calculates afterwards and the clearest read on a real estate asset’s cash flow.

Read it properly and a rent roll tells you the cash flow a property throws off before any financing, which is why it sits at the centre of how a rental property or a whole real estate portfolio is valued. Owners and property managers keep it current to track the rental income against budget; buyers use it to test the cash flow they are buying; lenders use it to size debt. Same document, three audiences, one number that has to hold up.

But a rent roll is a claim, not a fact, until it is tested. It states what the property should earn if every unit is let, every tenant pays, and every lease runs as written. A lender’s entire job on the income side is to work out how much of that claim to believe, and how much to discount. That process is the move from gross to net, and it is where the headline number starts to shrink.

The gross-to-net waterfall

Take the gross rent roll as the top of a waterfall and watch what a lender takes out on the way down.

First, voids. No building is full all the time. Tenants leave, units sit empty between lettings, and a lender assumes a void allowance rather than pretending the property is permanently at 100 percent. On an asset still filling up, the void assumption is larger, because occupancy is not yet proven.

Second, management and operating costs. Someone lets the units, chases the rent, maintains the building and insures it. On a block or a portfolio that is a real recurring cost, and a lender nets it off. A rent roll presented without any deduction for running the asset is presenting a number no owner actually banks.

Third, non-recoverable bills and service charge shortfalls. Where the landlord carries costs it cannot pass to tenants, those come out too. On some assets that is small; on others, particularly older or partly commercial buildings, it is material.

Fourth, incentives. This is the one borrowers forget. A rent roll can show a headline rent while the tenant is sitting inside a rent-free period or a stepped deal, so the passing rent today is below the figure on the schedule. A lender looks through the incentive to the rent actually being received now and the rent that will be received once the incentive burns off, and it does not simply take the top line.

What survives the waterfall is the net income, the real cash flow the rental property produces. That is the figure a lender applies its loan-to-value and interest-cover tests to. Good property management is what protects that cash flow, keeping voids low and the rental income landing on time, and a lender can see the quality of the management in how clean the rent roll is. On a settled, well-let asset the gap between gross and net is a known discount. On a rental property that is part-let, freshly refurbished or newly converted, the gap between gross rental income and net cash flow is wider and less certain, which is precisely the situation stabilisation debt is built for.

Scheduled rent versus passing rent

Two terms sit at the heart of every rent roll, and confusing them is one of the most common ways a finance request loses credibility.

Scheduled rent is the rent the leases and tenancies say should be paid: the contracted total if everything is fully let and running. Passing rent is the rent actually being received right now, after voids, arrears, incentives and unlet units. On a stabilised building the two are close. On a building mid-lease-up or just repositioned, passing rent can sit well below scheduled rent, because the units are not all let yet or tenants are still inside incentive periods.

A lender underwrites both, but it leans on passing rent for what it will lend today and on a credible scheduled figure for the path. A borrower who leads with scheduled rent as if it were passing rent is not being dishonest, but they are inviting the lender to do the correction for them, and lenders correct conservatively. Leading with the passing rent, then evidencing the route to the scheduled figure, is the presentation that holds up.

The building with two rent rolls

Here is the idea that makes stabilisation finance make sense, and it applies to almost every asset mid-journey.

The same building carries two rent rolls at once: the one it earns today, part-let and settling, and the one it will earn when it is full. Financing the gap between them is the entire job.

A newly built multi-unit block, a converted office, a refurbished parade or a park filling its pitches has a day-one rent roll, which is thin, and a stabilised rent roll, which is what the asset produces once occupancy, rents and incentives have matured. The day-one roll is what a lender can lend against conservatively today. The stabilised roll is what a term lender will refinance onto later. The distance between them is the stabilisation window, and the cost of bridging it is set against the income and value it produces.

This is why stabilisation debt is sized on the path to stabilised income, not on today’s income alone. A stabilisation bridge, indicatively from around 1 million pounds at up to 65 to 75 percent of value over 12 to 24 months, carries the asset across that window with interest serviced or rolled up while the rent roll matures. Once the stabilised roll is proven, a cash-out refinance or a senior investment term loan takes over, indicatively from around 500,000 pounds at up to 70 to 75 percent of the revalued figure over 5 to 25 years, sized so the net income covers debt service with headroom. If you want to see the shape of that gap before you request debt, the tools on stabilisationfinance.co.uk are built to measure the gap between a day-one and a stabilised rent roll so the ask matches the asset.

Evidencing a rent roll so a lender believes it

A rent roll is only as strong as the evidence behind it, and this is where cases speed up or stall. For residential units, that means the assured shorthold tenancies or leases themselves, showing the rent, the term and any incentives, backed by bank statements proving the rent is actually landing. For commercial units it means the leases, the schedule of terms, the review and break dates, and the tenant covenant behind each one. Across an asset that trades rather than simply lets, it means trading accounts, not projections.

Two rent rolls that show the same total are not equal if one is backed by signed leases and cleared payments and the other is a spreadsheet of hopes. A lender discounts the unevidenced roll far harder, because it has no way to test the claim. The single most useful thing a borrower can do before asking for debt is assemble the evidence pack so the rent roll can be believed on sight, which is the first thing the stabilisation desk assembles on any income case before it goes to a lender.

What the lender actually counts, in one line

Strip everything back and the rule is simple. A lender does not lend against the rent roll you show it. It lends against the net income that survives voids, costs and incentives, evidenced by leases and cleared payments, and on an asset mid-journey it lends today against the passing figure while sizing the exit against a credible stabilised figure. The whole art of financing an income asset in 2026 is closing the distance between the number the owner quotes and the number the lender counts, and doing it with evidence rather than optimism.

That principle runs across every asset class the same way, whether the income comes from a block of flats, a serviced accommodation operation, a supported living lease, an HMO portfolio or a holiday park. The vocabulary of the rent roll changes with the sector, but the move from gross to net, and from day-one to stabilised, does not.

The twelve-month read

For the rest of 2026, with the base rate held at 3.75 percent, the pressure on income-property finance is not coming from lurching rates. It is coming from lenders reading rent rolls carefully in a market where values have moved and occupancy assumptions matter. A rent roll presented gross, with scheduled rent dressed as passing rent and no evidence pack behind it, meets a harder audience than it would have in a looser market. A rent roll presented net, with passing and stabilised figures separated and every unit evidenced, gets underwritten on its merits.

For an owner refinancing or funding an asset this year, the message is plain. Do the gross-to-net work before the lender does, lead with the income that survives it, and show the path from the day-one roll to the stabilised one. That is what turns a rent roll from a claim into a fundable number.

FAQs

What is the difference between a gross and a net rent roll? The gross rent roll is the total contracted rent if everything is fully let. The net figure is what survives voids, management and running costs, non-recoverable bills and tenant incentives. A lender sizes debt on the net figure, not the gross, because the net is what an owner actually banks.

What is the difference between scheduled and passing rent? Scheduled rent is what the leases say should be paid when fully let. Passing rent is what is actually being received now, after voids, arrears and incentive periods. On an asset still stabilising the two can differ sharply, and a lender leans on passing rent for what it will lend today.

How can one building have two rent rolls? An asset mid-journey has a thin day-one rent roll and a mature stabilised rent roll it will reach once occupancy and rents settle. Stabilisation debt is sized on the path between the two, carrying the asset until the stabilised roll is proven and a term lender will refinance it.

What evidence does a lender want behind a rent roll? Signed leases or tenancies showing rent, term and incentives, bank statements proving the rent is landing, the schedule of lease terms and tenant covenants for commercial units, and trading accounts where the asset trades rather than simply lets. An unevidenced rent roll is discounted hard.
