We arrange commercial property development finance in Merton for schemes from around one million pounds of gross development value upward. Whether you are building student accommodation, a logistics unit, a care home or an office refurbishment, we model the capital stack and take it to the lenders most likely to fund that scheme in Greater London.

Commercial values turn on covenant, yield and sector demand, which we assess scheme by scheme. The local residential market is useful as exit context for mixed-use and conversion schemes: Merton is steady, with roughly 1,589 residential sales over the past twelve months at a £525,000 median, a read on liquidity for any homes within a scheme.

Funding the capital stack on a Merton development

We arrange the whole capital structure for Merton commercial schemes. Senior development finance funds the bulk of the build, typically to 65 to 70 percent of cost and 60 to 65 percent of gross development value. Stretch senior and mezzanine finance lift leverage when the appraisal supports it, reducing the equity you commit. JV equity fills the remaining gap for developers scaling beyond their own balance sheet. For operational schemes that let up or trade after completion, such as student accommodation, care homes, hotels or self-storage, stabilisation finance carries the asset from practical completion through to stabilised income. Once the scheme is stabilised or sold, development exit finance refinances it onto cheaper money while units sell or let, releasing equity for the next site in Greater London.

The commercial sectors we fund in Merton

Each commercial asset class is underwritten on different tests by different lenders, and we arrange finance for all of them in Merton and across Greater London. That covers student accommodation and offices, warehouses and logistics, care homes and healthcare, retail, hotels and leisure, industrial and mixed-use schemes, and the higher-growth classes of self-storage, data centres and life sciences. Knowing which lender backs which sector here, and at what leverage, is the work we do before a scheme ever reaches a credit committee.

Development conditions in Merton

Merton is a mid-market location within Greater London, where development margins depend on disciplined costs and a realistic exit. That profile suits senior development finance with a modest stretch or mezzanine top-up, and it is among the more straightforward backdrops for a lender to underwrite.

Residential market depth as exit context

Residential sold-price depth is one input a development lender uses to gauge exit liquidity, particularly for the residential element of mixed-use, build-to-rent and conversion schemes. Merton recorded around 1,589 residential sales over the past year at a median of £525,000, which makes the local market steady. New-build stock carries a premium of -29% over existing stock here. Commercial values turn on covenant, yield and sector demand, which we assess scheme by scheme.

This residential mix is exit context for the homes within a mixed-use or conversion scheme. It is not a guide to commercial values, which are sector and covenant driven.

FAQ

Commercial property development finance in Merton: common questions

How much commercial property development finance can I raise in Merton?

Most senior lenders fund up to 65 to 70 percent of total cost, capped at 60 to 65 percent of gross development value, with stretch senior or mezzanine lifting that toward 85 to 90 percent of cost on a strong scheme. The Merton exit market, currently steady, informs the gross development value a lender will accept.

Which lenders provide development finance in Merton?

We hold more than one hundred lender relationships across banks, challenger banks, debt funds and private capital. The right lender for a Merton scheme depends on the sector, the leverage you need and your track record, and we shortlist the desks most likely to back it across Greater London.

How does the Merton residential market affect a commercial scheme?

It matters mainly as exit context for the residential element of mixed-use, build-to-rent and conversion schemes. HM Land Registry records a £525,000 residential median in Merton over the past year across roughly 1,589 sales, with flats around £381,000. Commercial values, by contrast, turn on covenant, yield and sector demand, which we assess scheme by scheme.

Do you fund commercial development beyond Merton?

Yes. We arrange commercial property development finance across the whole of Greater London and the wider UK, with the same approach: model the capital stack, match the scheme to the lenders that back its sector, and negotiate terms on the developer's behalf.
