Lease-up Finance 2026

A newly built block of flats, a freshly opened self-storage store or a converted hotel has the same problem on day one: the building is finished, but the income is not there yet. Tenants have to move in, rooms have to fill, occupancy has to climb from a standing start toward the level a long-term lender wants to see before it will put cheap, patient debt against the asset. That climb takes months, sometimes years, and the asset still has bills to pay while it happens. Somebody has to fund the asset, and the lettings push behind it, until the income arrives. That is what lease-up financing is for.

The thing to understand before you arrange lease-up finance is that the loan is not really sized on the building you can see today. It is sized on the income the building will produce once it is full. A lender looks past the part-let asset in front of it and underwrites the path to a stabilised income that does not yet exist. The bricks matter as security, but the lettings plan and the occupancy curve are the real underwriting. Get the lettings plan right and credible, and the financing follows.

This article walks through lease-up financing as it stands in 2026: what the funding covers, why it is sized on projected stabilised income rather than today’s, why the occupancy trajectory and the lettings plan are the part a lender reads hardest, where loan to value and term sit, how the term exit works once income is proven, how lease-up finance differs from a term loan, and how lease-up differs by asset class. The figures here are indicative market commentary for UK property stabilisation finance, illustrative and never an offer of finance. We are an arranger: we place and structure these deals with the lenders whose appetite fits them, and we do not lend ourselves.

What lease-up finance covers

Lease-up finance is short-dated debt that funds an asset through the income ramp, from a part-let or recently completed state to stabilised occupancy. It sits in the family of stabilisation finance, the short-dated debt that carries a newly built, refurbished or recently let property from practical completion, through lease-up, to the settled income a long-term lender wants. Where a development loan funds construction, lease-up finance is aimed squarely at the lettings period itself: the window between a finished building and a full one.

In practice it covers two related needs. The first is carrying the asset financially while it is only partly let: a part-let block produces some income, but not enough to service long-term investment debt at a sensible loan to value, so lease-up financing bridges the shortfall and protects the cash flow while the building fills, giving the owner room to let the rest of the space without being forced into a fire-sale or an awkward early refinance. The second is funding the lettings push itself, the marketing, incentives, management and working capital that filling a building takes, so the owner can let the space at pace rather than starve the push of cash.

Lease-up finance is not development finance, which is sized against build cost and gross development value, and it is not a long-term investment term loan, the patient money that sits on a stabilised asset for years. It is the bridge between those two loans, priced above a stabilised term loan and below construction debt, which reflects where it sits on the risk curve: past the build, but not yet at a settled income. Its job is to buy the time the income needs to arrive.

The market backdrop says the money is there for the right plan. The UK bridging and development loan book stood at about 13.4bn at the end of Q4 2025 on the BDLA’s count, up more than 50% year on year from about 10bn in 2024, with applications at about 11.7bn in Q4. There is deep, active appetite among the lenders who write lease-up financing at this stage. The question on any given asset is the credibility of the lettings plan, not whether capital exists to back it.

Sized on projected stabilised income, not today’s

This is the single most important idea in lease-up financing, and the one that trips up owners used to ordinary investment lending. A normal term loan is sized on the income the asset produces now, while lease-up finance is sized on the income the asset is projected to produce once it is stabilised. The lender underwrites forward: it forms a view of the stabilised net income at the end of the lettings period, sizes the facility against that, and then controls the risk along the way as occupancy builds toward it.

The reason is structural, and it is common to all income-producing real estate. Value in commercial property is income divided by a capitalisation rate, the prime yield for the sector. At practical completion the income is low or close to nil, so the day-one value is low too; once the asset is full, the income is at its mature level and the value is far higher. The gap between the day-one value and the stabilised value is the space lease-up finance is set against. A lender advances against the path to that stabilised value while protecting itself on the lower day-one position, which is why the loan to value test is applied to a value that rises as the asset lets up, not frozen at the day-one number.

That forward sizing is disciplined, not optimistic. A lender takes a conservative view of where stabilised income will land, often haircutting the projected occupancy or rent to allow for a slower ramp than the lettings plan hopes for, then checks that the stabilised income, once reached, will clear its debt service cover and debt yield thresholds comfortably, because those are what let the asset refinance at the end. The covenant question through lease-up is not whether today’s income covers the debt. It is whether the lettings plan, and the path to the stabilised income it describes, is believable. That is a different test, and it is why the plan does so much of the work.

The prime yield is doing double duty in this sizing: it sets the eventual stabilised value, and it tells the lender how liquid the exit will be, since a tighter yield means a higher stabilised value and a deeper pool of refinancing capital waiting at the end. Indicative prime yields sit, on the research-house numbers, at roughly 4.25% for prime London build-to-rent multifamily and about 4.50% for Tier 1 regional cities on Knight Frank’s November 2025 guide, about 5.0% for prime UK self-storage on Savills’ Q4 2025 read, and roughly 4.25% to 4.50% for prime London PBSA against 5.25% to 5.50% regional on Knight Frank’s count. Those are quoted for stabilised, institutional-grade assets only. A lease-up asset will not transact at the prime yield until it is stabilised, which is the whole point of the finance.

The lettings plan and the occupancy curve are the underwriting. The bricks are just the security.

The occupancy trajectory and the lettings plan

If the loan is sized on projected stabilised income, the lettings plan is the document that has to make that projection believable, and the occupancy trajectory is how a lender measures whether the plan is being delivered. These two things are the real underwriting. A lender reading a lease-up proposal spends far more time on the absorption rate, the lets per week or per month, than on the specification of the finishes.

The lettings plan is the operating plan for the asset. It sets out how the space gets filled: the pricing, the incentives, the target tenant or guest, the marketing spend, the management resource and the timeline. A credible plan is specific. It says how many units or rooms will let in each period, at what rent or rate, what rental growth is assumed as the building fills, and what the run-rate to stabilisation looks like month by month, evidenced by comparable schemes in the same market, the local supply and demand picture, and any pre-lets, nominations or reservations already in hand. A vague plan that promises to be full in a year without showing the arithmetic gets priced harshly or declined.

The occupancy trajectory is that lettings plan turned into a curve, and the absorption rate is what underwriters watch once the financing is drawn because it is the early warning system on income growth. If the curve tracks the plan, the refinance exit comes into view; if it lags, the lender sees it early and can work with the owner before it becomes a problem. This is also why margins are often set to step down as the asset hits agreed occupancy milestones, rewarding a scheme that lets up faster with a cheaper rate.

This matters more in 2026 because lease-up risk is being priced more carefully across the board. Logistics vacancy, on CBRE’s count, was about 7.1% at Q4 2025, edging up on rising second-hand availability, so even in a strong sector the timing matters. In the living sectors, PBSA private-sector occupancy softened to about 85.4% for the 2025/26 cycle on the StuRents data reported by Cushman and Wakefield, against a pre-Covid norm of 95% to 98%. When occupancy at the mature end has softened, a lender reads a first-cycle lettings plan with more scrutiny, and the quality of the plan does more to set the terms.

LTV indicatively 65% to 75%, 12 to 24 months

Loan to value on a lease-up facility lands indicatively at 65% to 75% of value, with the position in that band set by the lettings plan. A scheme in a sector with a fast, proven absorption pattern, in a strong location, with pre-lets or nominations already in hand sits at the keener, higher end. A scheme with a slower expected ramp, a more uncertain market or no advance lettings sits lower, because the lender is leaving more headroom against the day-one value while the income is still building. The loan to value is calibrated to the certainty of the ramp, not handed out as a fixed percentage.

The term runs indicatively 12 to 24 months, sized to cover the lease-up period with a sensible margin for the refinance to be arranged at the end. That is the window most sectors need to reach a stabilised, or near-stabilised, occupancy from a part-let start, so the income ramp and the loan term line up. A self-storage store, which fills more slowly, may need the upper end or a structure that anticipates a longer fill, while a build-to-rent block targeting around 80% occupancy inside twelve months can often work comfortably within the standard term.

Loan sizes start from around 1m, with no fixed ceiling on a strong asset. Repayment is typically interest-only, or interest rolled up while occupancy builds, so the asset is not asked to service a full amortising loan out of an income that has not yet arrived. Rolling up the interest also protects the cash flow the lettings push itself needs. As always, these bands are indicative and illustrative: they vary by lender, asset class, location and the specifics of the scheme, and none of them is an offer of finance.

The cost of that debt is anchored, in 2026, by a Bank of England base rate of 3.75%, held since the December 2025 cut and unchanged into the middle of the year. Short-dated lease-up facilities are typically priced as a margin over SONIA, the sterling overnight benchmark that tracks the base rate closely, so 3.75% sets the floor under the rates on offer for carrying an asset through lease-up. With prime yields broadly stable to modestly hardening, the average prime equivalent yield was about 5.91% at end-2025 on Savills’ read against about 5.98% a year earlier, the margin between the cost of debt during lease-up and the prime yield at exit is the heart of the deal. Where that margin is thin, in the keenly priced living sectors, the day-one advance is more conservative and the plan has to be tight.

The term exit once income is proven

Lease-up finance is built to be repaid, and the exit is the refinance onto a long-term investment term loan once the income is proven. This is not an afterthought: the exit is underwritten at the start, because a lender providing the lease-up facility wants to see, before it advances, that there is a credible route off its book at the end. The whole structure is a relay: short-dated debt carries the asset across the lettings period, then hands over to patient term debt the moment the income clears the threshold a term lender needs.

Proven means the occupancy has reached, or is close to, the stabilised level set out in the lettings plan, and the income has settled enough that a term lender can size a long-term loan against it with confidence. At that point the stabilised income covers debt service with headroom, the debt yield clears the term lender’s threshold, and the asset can be valued on its mature income at the sector’s investment yield. The investment term loan then refinances the lease-up facility, the short-dated debt is repaid, and the asset moves onto debt that can sit on it for years, indicatively 5 to 25 years, priced as a margin over SONIA or base or as a fixed rate. The two loans differ in patience: the lease-up loan carries the risk of the ramp, the term loan rewards the proven income.

The cleaner version is to arrange the term exit alongside the lease-up facility rather than scrambling for it at the end. Where it fits, a bridge-to-term structure lets the long-term loan be lined up at the outset, sized on the stabilised income the asset is expected to reach, with the first legal charge carried across from the short-dated facility to the term loan. That removes the refinance risk that otherwise hangs over the end of a lease-up, and it is one of the things we look at early when we structure a deal, because knowing the exit is in place changes how comfortably the lease-up facility itself can be priced.

A sale is the other exit, and it turns the stabilised asset into cash rather than refinanced debt. An owner letting up a scheme to sell it as a stabilised investment rather than to hold uses lease-up financing to get the asset to the point where it trades at the keen stabilised yield rather than the discounted day-one value, the same uplift a buyer chases on an acquisition of a part-let asset they intend to fill. The lettings plan is still the underwriting, because the buyer and the buyer’s lender will read the same occupancy curve. Either way, the financing is short-dated and repaid out of a proven income, whether that income is refinanced or sold.

Across asset classes: PBSA, BTR, self-storage and more

The lease-up structure is the same across asset classes: complete or reposition, let up or ramp the trading, reach a stabilised income, refinance or sell. What changes is the income basis and, above all, the shape and length of the occupancy curve, and that is what changes how the financing is priced and sized. A fast ramp versus a slow one is the single biggest driver of terms. A lender reads the income basis to judge how fast and how certain the stabilised income, and the income growth behind it, will be. Here is how the ramps differ, on the research-house numbers.

Build-to-rent ramps monthly and quickly. A typical BTR lease-up target, on CBRE’s read, is about 80% occupancy within twelve months of going live, ramping to a stabilised level above 95% thereafter, with average tenancies around 24 months. Because that ramp is relatively fast and the demand pattern is well understood in strong locations, lease-up finance on a good BTR scheme can sit toward the keener end of the bands, especially with the BTR market as deep as it is now: UK stock is past 146,700 completed homes on Savills’ count, up about 13% year on year, with a record Q4 2025 of nearly 2.7bn invested.

Self-storage fills slowly, and the finance has to respect that. A storage store is as much a trading business as a piece of real estate, and a new store opens at low occupancy and takes a fill-up of about 36 months, roughly three years, to reach a mature level, longer in saturated markets, on the StoragePug rule of thumb and the Cushman and Wakefield and SSA UK data, which put mature stores at about 79% occupancy and overall occupancy at about 75.1%. That long, gradual curve means a storage facility is usually structured with a longer horizon or a clear interim milestone, and the lender prices the extended window. The trade-off is that prime self-storage stabilises onto a keen yield, about 5.0% on Savills’ Q4 2025 read, so the stabilised value at the end is strong.

PBSA is the sharpest case, because the income arrives in a single concentrated burst. A new student scheme completes just before the academic year and has to let up across one September intake to reach stabilised income, with no second chance until the next cycle. That makes the lettings plan unusually high-stakes, and the softer 2025/26 occupancy of about 85.4%, against the 95% to 98% pre-Covid norm on the StuRents data, means first-cycle lease-up risk is being priced more carefully. A lender wants strong demand evidence, and nomination agreements with a university, which take blocks of beds on a multi-year basis, materially de-risk the let-up and improve the terms.

Beyond these three, the pattern repeats with its own income basis. Hotels and aparthotels are operating businesses first and real estate second, so they open with sub-market trading and take about 18 to 36 months to ramp occupancy and rate to a stabilised income, with UK hotels rebounded in the second half of 2025 to about 82.5% occupancy in London and about 79% regionally on Knight Frank’s read, so the lender underwrites a trading ramp rather than a simple lettings curve. Care homes, another operating business wrapped in property, ramp over roughly 12 to 24 months, with nationwide occupancy about 88.7% in 2025 on Knight Frank’s count. Speculative logistics lets up over roughly 6 to 18 months, and HMO portfolios fill room by room and often need an evidenced rent roll before a term lender will refinance. A trading asset like a hotel makes the lender read the ramp harder than a pure lettings asset like a flat block, but in every case the structure is identical and the income basis tells the lender how to price the lease-up financing.

Talk to us

If you are financing an asset through its lease-up, the earlier we see the lettings plan and the occupancy trajectory, the better we can shape the financing around them. We start where the lender starts: with the projected stabilised income, the income growth the ramp assumes, the credibility of that ramp and the route to a term exit. We also help you see why a lease-up facility fits your scheme where an ordinary term loan does not. From there we form an early view on where loan to value and the rate are likely to land, so we can tell you whether your scheme is a 75% proposition at the keen end with pre-lets in hand or a slower ramp that needs a more conservative structure and a longer horizon. Then we place the deal with the lender camps whose appetite genuinely fits the stage and the sector, rather than sending it everywhere, and we line up the term exit alongside the facility wherever that fits.

The financing for lease-up sits mainly with specialist real estate debt funds and bridging lenders, who carry the deepest appetite for the income ramp and understand the lettings push behind it, with challenger banks and senior investment lenders, including clearing and insurance-backed lenders, taking over once the asset is stabilised and well let, and with mezzanine and preferred-equity providers for the stretch where the senior advance leaves a gap. We never name them individually, but matching the deal to the right camp is most of the job. To get started, talk to a stabilisation finance specialist.
