Mezzanine finance for apartment schemes

Apartment schemes concentrate a lot of value and a lot of cost into a single structure. A block delivers its units in one completion event rather than plot by plot, which changes the funding profile: peak debt is higher, the build is longer and the sales or letting period is compressed into the months after practical completion. Demand for well specified flats near transport and amenity remains strong in most UK cities, but the capital intensity is what stretches developers.

Senior lenders price flatted development more cautiously than houses because the exit is lumpier and the market for a whole block is thinner than for individual homes. That often pulls the senior layer back toward 60 percent of cost on larger blocks, widening the equity gap. Mezzanine bridges that gap and takes combined leverage to as much as 90 to 95 percent, and we look closely at the sales rate, the presale position and the specification against the local market.

A typical apartment schemes capital stack

Larger flatted blocks often see senior debt held nearer 60 percent, so the mezzanine layer works harder than on plotted housing. Illustrative only; every stack is sized case by case.

Why apartment finance behaves differently

A house scheme sells plot by plot, so debt reduces steadily as each home completes. A block does not. The units arrive together at practical completion, peak debt is carried for longer, and the sales or letting period sits at the end rather than running through the build. Senior lenders read that as concentration risk, and on larger blocks many pull their limit back toward 60 percent of cost rather than the 65 percent they might offer on housing. The result is a wider equity gap on exactly the schemes that already demand the most capital.

Mezzanine finance is well suited to this shape. It fills the space between a more cautious senior facility and a thin equity slice, and it is sized to be repaid from the sell-down rather than serviced from day one. On a six million pound block with senior debt at 60 percent, mezzanine can lift combined leverage toward 90 percent and leave the developer with a far smaller cheque to write up front.

How mezzanine changes the equity maths

The extra finance cost of a flatted scheme has to be earned back over a longer hold, so the margin matters even more than on housing. What mezzanine buys is optionality: rather than sinking three million of equity into one block, a developer can hold a stake in two or three and let the pipeline compound. The mezzanine leverage calculator makes the effect concrete, and our guide on structuring a 90 percent LTC capital stack walks through how the layers fit together on a block.

Exit routes we underwrite to

Most apartment schemes exit through open-market unit sales in the year after completion, and a strong marketing suite and named selling agents count for a lot. Increasingly, developers hold blocks as single-title investments and exit onto an investment facility once the units are let, which suits a build-to-rent style hold. We size the term to whichever route is realistic and give room for a compressed but real sell-down rather than assuming every unit clears on day one.

What our underwriting focuses on

• The absorption rate: how many units the local market realistically clears per month
• Specification and service charge against comparable local blocks
• Any presale, off-plan or block-sale position that de-risks the exit
• Cladding and building-safety compliance on the design and materials

Building-safety rules now shape both saleability and lender appetite on flats, so we expect the design to be compliant and documented. Where a scheme suits senior stretch better than a discrete mezzanine layer, we can arrange senior development finance whole of market instead.
