Forward commitment for build to rent

The structure where an institutional investor agrees to buy a build-to-rent scheme on practical completion at a fixed price and yield, but does not fund the construction, so the developer funds the build and takes the development risk in exchange for keeping more of the upside.

What is a forward commitment in build to rent?

A forward commitment, also called a forward purchase, is the structure in which an institutional investor agrees at the outset to buy a build-to-rent scheme on practical completion, at a price and yield fixed in advance, but does not fund the construction. The developer funds the build, usually with development finance, delivers the scheme, and the investor pays on practical completion. It gives the developer a committed buyer without the investor taking on the funding of the build, which sits it between a speculative build and a forward funding deal.

The defining feature of a forward commitment is who funds the build and who carries the risk. Because the investor does not fund the construction, the developer raises development finance, commits equity and carries the build risk, the cost risk and the lease-up risk through to practical completion. In return, the developer keeps more of the development upside than under forward funding, where the investor funds the scheme and takes the development-risk margin. The investor, paying only on completion, takes less risk than under forward funding and so usually pays a price reflecting a slightly keener yield than an open-market stabilised purchase, but less keen than it would demand for funding the build.

For the developer, the value of a forward commitment is certainty of exit. A speculative build-to-rent scheme is delivered in the hope of selling or refinancing at the end, exposed to where investment yields and investor appetite sit on completion. A forward commitment locks in the buyer and the price before construction starts, which de-risks the exit and makes the development finance easier to arrange, because the lender can see a committed institutional purchaser behind the scheme. Knight Frank reports around 40 billion pounds committed to UK build-to-rent over the decade to 2025.

We arrange forward commitments by introducing schemes to the institutional investors and funds active in the sector, structuring the price, the yield and the completion conditions, and arranging the development finance that funds the build alongside the commitment, so the two fit together and the scheme is funded from the ground up with a buyer already in place.

Process

How a forward commitment is arranged

Scheme and investor fit

We assess the scheme and its stabilised income, then introduce it to the institutional investors whose strategy and yield requirements fit a purchase on practical completion.

Fix the price and yield

We help structure the forward purchase agreement, fixing the price and entry yield, the completion conditions, and any letting or quality thresholds to be met before the investor pays.

Fund and build the scheme

The developer funds the build with development finance and equity that we arrange alongside the commitment, and delivers the scheme on budget and on programme.

Complete the sale on PC

On practical completion, and once the agreed conditions are met, the sale completes to the committed investor at the fixed price, repaying the development finance.

Who can use a forward commitment and what investors look for

Institutional investors give forward commitments on schemes that fit their long-term strategy and to developers they trust to deliver, because although they do not fund the build they are relying on the developer to complete the scheme to the agreed standard and let it. They look for a planning consent in place, a credible contractor and build contract, a realistic programme, and a stabilised net operating income that supports their target entry yield, which Knight Frank put at around 4.50 percent for prime regional multifamily and around 4.25 percent for Greater London in September 2025. They will set completion conditions, often including a minimum letting level or quality standard, before they are obliged to pay. Because the developer is funding the build, the developer also needs to satisfy a development lender, so the case has to work twice over: it has to be a scheme an investor will commit to buy and a scheme a lender will fund. That dual test is, in practice, a strength, because a committed institutional buyer behind a scheme gives the development lender confidence in the exit and can improve the terms of the development finance. We present the scheme so it stands up to both the investor's purchase underwriting and the lender's development underwriting.

How a forward commitment affects your funding

Under a forward commitment the developer funds the build, so the capital position looks like a development finance deal with a committed exit attached. The developer raises senior development finance, typically up to around 60 to 65 percent loan to cost or 70 to 75 percent loan to GDV, and commits the balance as equity, usually 35 to 40 percent of cost, then delivers the scheme. The difference from a speculative build is the exit: instead of hoping to sell or refinance on completion, the developer has a buyer and a price fixed in advance, which removes the exit-yield risk and usually makes the development finance easier and keener to arrange, because the lender can see a committed institutional purchaser. The price the investor pays is set by the stabilised net operating income capitalised at the agreed entry yield, so the yield drives the number: Knight Frank put Tier 1 regional multifamily at around 4.50 percent in September 2025. Because the developer carries the build through to completion, the developer keeps more of the development margin than under forward funding, where the investor funds the scheme and takes that margin. We model the development finance, the equity requirement and the fixed completion price together, so you can see the cash you commit, the risk you carry and the profit you keep against a forward funded alternative.

Costs and the risk-reward trade

A forward commitment carries the costs of the development finance the developer raises to fund the build, plus the professional costs of the forward purchase agreement. The development facility is priced indicatively a margin over SONIA, roughly 7 to 10 percent all-in for senior debt, with interest usually rolled up, plus an arrangement fee of around 1 to 2 percent, monitoring surveyor costs, valuation and legal fees. On top sit the legal and structuring costs of the forward purchase agreement itself. The benefit set against those costs is a committed buyer at a fixed price, which removes the exit-yield risk and can reduce the cost of the development finance, because a lender funding a scheme with an institutional buyer already behind it can often lend more keenly. The trade-off against forward funding is clear: a forward commitment costs the developer more, in development finance and risk, but returns more of the development upside, because the investor pays only on completion and so takes the smaller margin. We disclose our broker fee in writing, set out the full cost of the development finance and the agreement against a forward funded alternative, and never claim an exclusive tie to any lender or investor.

Forward commitment, forward funding or a speculative build

A forward commitment is the right structure when you want the certainty of a committed institutional buyer but would rather fund the build yourself and keep more of the development upside. It carries more risk than forward funding, where the investor funds the land and construction and takes the development-risk margin, but less risk than a speculative build, where you fund the scheme and rely on the open market to sell or refinance it on completion at whatever yield prevails. Set against build-to-rent as a hold, a forward commitment is a clean exit at a price fixed in advance, whereas holding the scheme means arranging investment finance and managing the asset long term. The choice turns on how much risk you want to carry and how much upside you want to keep: forward funding is the safest and gives up the most, a speculative build is the riskiest and retains the most, and a forward commitment sits in between with a committed buyer. We model each against your scheme so the structure fits your appetite, not a single lender's product set.

FAQ

Forward commitment: common questions

What is the difference between forward funding and a forward commitment?

Under forward funding, the institutional investor funds the land and the construction up front and buys on completion, so the developer needs little equity but gives up more upside. Under a forward commitment, or forward purchase, the investor agrees to buy on practical completion at a fixed price but does not fund the build, so the developer funds construction with development finance, carries more risk and keeps more of the upside.

What is the difference between BTR and BTS?

Build to rent, or BTR, is housing built to be held and let, valued on its stabilised rental income and an investment yield. Build to sell, or BTS, is housing built for individual sale, valued on unit sale prices and funded by a development loan repaid from those sales. A forward commitment applies to BTR: the scheme is built to be let and sold as an income-producing asset to an institutional investor.

Is build to rent worth it?

For developers, build to rent offers a route to a committed institutional exit and access to a sector that saw a record 5.3 billion pounds of UK investment in 2025, per Savills, against acute rental demand, with the private rented sector at around 19 percent of English households. Whether a specific scheme works depends on the build cost, the achievable rents, the stabilised net operating income and the yield. We model the income and the exit before you commit.

What are the risks of forward funding?

Under forward funding the investor takes development risk, funding a scheme before it exists, so cost overruns and delays fall on the funder unless passed to the developer. Under a forward commitment the developer carries that build risk instead, because the developer funds the construction and is paid only on completion once the agreed conditions are met. The structure determines where the risk sits, which is why we model both.

Does a forward commitment make development finance easier to get?

Often, yes. A committed institutional buyer at a fixed price behind the scheme gives the development lender confidence in the exit, which can improve the terms and the loan to cost the lender will offer. We arrange the development finance alongside the forward purchase agreement so the two fit together and the lender can see the buyer behind the scheme.

What is the 2 percent rule for property?

The 2 percent rule is an investor rule of thumb suggesting monthly rent should be around 2 percent of a property's purchase price. It is a quick screen, not how institutional BTR is underwritten. A forward commitment is priced on the stabilised net operating income capitalised at an agreed entry yield, which Knight Frank put at around 4.50 percent for prime regional multifamily in September 2025.
