Build to rent development finance

Lending criteria and what funders look for

Build to rent development lenders fund experienced developers and housebuilders, or first-timers who bring in a proven team. Their lending criteria centre on a planning consent in place or close to it, a fixed-price or well-controlled build contract, a credible contractor with a track record on similar schemes, and a realistic programme with contingency. Because the scheme is held and let rather than sold, they look hard at the income the finished homes will produce: the achievable rents, the stabilised net operating income, the gross-to-net ratio after voids and operating costs, and the yield a stabilised asset would command, which Knight Frank put at around 4.50 percent for Tier 1 regional cities in September 2025. They expect the developer to commit meaningful equity, usually 35 to 40 percent of cost, so the borrower has capital at risk alongside the lender, and they want a credible exit, whether a refinance onto investment finance, a development exit facility, or a forward sale to an institutional investor. Demand context supports the case: the English Housing Survey puts the private rented sector at around 19 percent of English households, about 4.7 million homes, and the ONS records average UK private rent up 3.3 percent in the year to May 2026. We package the scheme, the team, the planning position and the income evidence so the lender can see the homes built on budget and let on plan.

How much you can borrow

Development lenders work to two limits and lend to the lower of them. Loan to cost is the share of total development cost they will fund, indicatively up to around 60 to 65 percent, with the developer providing the balance as equity. The second limit caps the loan at a share of the gross development value the finished, stabilised scheme will reach, indicatively up to around 70 to 75 percent loan to GDV, which protects the lender against an over-optimistic appraisal. The achievable loan therefore depends as much on the stabilised GDV, driven by the rent roll and the yield, as on the build cost. Because a build-to-rent scheme is valued on its income, the yield matters: Knight Frank put Greater London prime multifamily at around 4.25 percent and Tier 1 regional cities at around 4.50 percent in September 2025, and a keener yield lifts the GDV on the same net operating income. On a strong scheme with a healthy development margin, a mezzanine layer or equity can sit behind the senior facility to stretch total leverage toward 80 to 90 percent of cost, closing part of the equity gap. We run both senior limits, the equity requirement and any mezzanine top-up from the appraisal, so you know your true cash commitment before you commit, and the Savills pipeline, which shows 146,700 completed BTR homes with 50,600 under construction and 101,500 in planning, confirms there is depth of lender appetite behind well-structured schemes.

Rates and costs

Build to rent development finance is priced for construction risk and is dearer than the investment debt that refinances it, indicatively a margin over SONIA that works out at roughly 7 to 10 percent all-in for senior debt, usually with interest rolled up and added to the loan rather than serviced, then repaid on exit. Expect a lender arrangement fee of around 1 to 2 percent, an exit fee on some facilities, a monitoring surveyor's cost for the staged drawdowns, a valuation reporting on cost and stabilised GDV, and legal fees for both sides. Because interest rolls up, the length of the build and lease-up period drives the total finance cost, so a tight, well-run programme saves real money and an overrun is expensive twice over, in extended interest and in a delayed exit. Where mezzanine or equity sits behind the senior debt, it carries a higher coupon, low-to-mid teens, reflecting its subordination, which only works where the development margin is healthy enough to carry it. We disclose our broker fee in writing, compare facilities on total cost to exit rather than the headline rate, and never claim an exclusive tie to any lender.

Development finance, forward funding or a development exit

Build to rent development finance is the right product when you are building a rental scheme, hold the development risk yourself and want senior debt to fund the construction. It differs from forward funding, where an institutional investor funds the land and build up front and acquires the completed scheme, reducing your equity need but handing the investor the development upside, and from a forward commitment, where the investor agrees to buy on practical completion but does not fund the build, so you still fund construction with development finance. Once the scheme reaches practical completion and starts to let, the development loan is repaid by a development exit facility, which is cheaper and carries the scheme through lease-up, then by longer term investment finance once the rent roll stabilises. If you would rather not carry the development risk at all, forward funding is the structure to consider. We map the full route from site to stabilised, income-producing asset so each stage uses the right funding at the right price.
