MUFB Bridging Loans - Multi-Unit Freehold Block Finance
Bridging finance for multi-unit freehold blocks - acquisitions, conversions and refinances. Fast capital deployment for competitive block purchases.
What is MUFB bridging finance?
A Multi-Unit Freehold Block (MUFB) is a single freehold title containing multiple self-contained residential units - typically purpose-built flats, converted houses, or commercial-to-residential conversions. MUFB bridging is short-term finance used to acquire or refinance these blocks, distinct from HMO finance because each unit is a self-contained dwelling rather than shared accommodation.
Bridging is the natural product for MUFB acquisitions because blocks usually go to sealed bid or competitive process and need a cash-equivalent offer. The facility typically runs 6-12 months and exits onto a specialist MUFB commercial mortgage, individual unit sales, or refinance onto a portfolio mortgage. Lenders price on the investment method, applying a yield to projected or actual rental income.
When MUFB bridging is the right tool
Sealed-bid acquisitions of freehold blocks
Blocks of flats frequently sell via sealed bid with 4-6 week exchange. Bridging makes the offer credible.
Buying a partly-tenanted block from a portfolio disposal
Portfolio landlords selling mixed blocks need committed buyers - bridging removes finance contingency.
Acquiring a vacant block for repositioning or sales
Vacant blocks valued on GDV or VPV are bridgeable while the exit (sales or letting strategy) is executed.
Commercial-to-MUFB conversion
Office or retail buildings converted to flats need bridging to fund acquisition while planning and works progress.
Replacing a maturing commercial mortgage
Short-term bridge buys time to restructure or refinance onto a new long-term MUFB facility.
Acquiring a freehold reversion under right-of-first-refusal
Section 5 RTFR purchases run on statutory timelines that mainstream finance cannot meet.
MUFB bridging - typical lender criteria
| Loan size | £500k - £25m |
|---|---|
| LTV | 65-75% |
| Minimum units | 2 (most lenders require 4+) |
| Rates | 0.65% - 0.85% pm |
| Term | 6 - 18 months |
| Valuation | Investment method (tenanted) or GDV/VPV (vacant) |
| Exit | MUFB commercial mortgage, block sale, or unit-by-unit sales |
Blocks of 4-20 units are most liquid; larger blocks may require private bank appetite. Gross yield of 6%+ typically required by lenders for investment-method valuation. Empty blocks valued on GDV or VPV; tenanted blocks valued on income. Larger blocks (50+ units) move into bespoke private bank territory.
Why block investors use Doulton
Block acquisitions consistently rely on two things mainstream lenders struggle with: speed of decision under sealed-bid pressure, and willingness to value a partly-tenanted block on a blended methodology. Doulton's panel includes the specialist lenders comfortable with both. We deliver indicative terms inside 24 hours of receiving the deal pack, which is what makes a sealed-bid offer credible.
We also model the exit carefully. Block bridges fail most often when the borrower's exit lender turns down the underlying block valuation or unit mix. We engage the long-term MUFB mortgage provider in parallel with the bridge so the exit lender's criteria are agreed in principle before the bridge funds - removing the single biggest risk in the deal.

Case study - 12-unit South London block, sealed bid
£1.7m bridging loan - partly-tenanted freehold block
The challenge
A portfolio landlord identified a 12-unit South London freehold block for £2.4m through a competitive sealed bid process with a 21-day exchange requirement. The block was partly tenanted (7 of 12 units), making the mixed valuation methodology unattractive to mainstream commercial lenders.
The approach
Doulton placed the case with a specialist MUFB bridging lender comfortable with blended income/VPV valuation methodology. Indicative terms were issued within 24 hours, supporting a credible sealed bid. A specialist block valuer assessed the tenanted units on income and the vacant units on GDV, producing a blended value of £2.4m supporting a 71% LTV bridge of £1.7m.
The outcome
Completion in 10 working days. The borrower let the remaining 5 units in months 1-5, increasing the income basis of the valuation. At month 8 Doulton arranged the exit onto a long-term MUFB commercial mortgage at 70% LTV based on the now-stabilised income, with no rate premium for the bridge-to-term transition.
Bridging Finance for MUFB (Blocks of Flats) - frequently asked questions
What is a MUFB and how does bridging finance work for one?
A Multi-Unit Freehold Block (MUFB) is a single freehold title containing multiple self-contained residential units - typically purpose-built flats or a converted house broken into separate dwellings. Bridging is the standard finance product for MUFB acquisitions because blocks often sell via sealed bid or short-deadline auction. The bridge funds the purchase at 65-75% LTV, then exits onto a long-term MUFB commercial mortgage typically within 6-12 months as the block's income stabilises.
What LTV is available on a multi-unit freehold block bridging loan?
65-75% LTV is the standard range, with the higher end reserved for fully-tenanted blocks of 4-20 units in strong locations. Vacant or partly-vacant blocks tend to attract 65-70% LTV because the income valuation cannot be fully relied on. Larger blocks of 30+ units sometimes attract lower LTVs as the lender appetite narrows to private bank players. Loan sizes range from £500k to £25m+ depending on lender.
Can I bridge on a block of flats that is partly vacant?
Yes. Specialist MUFB bridging lenders are comfortable with partly-tenanted blocks and apply a blended valuation methodology - tenanted units on investment method (yield against actual rent) and vacant units on either market value or GDV. The blended figure drives the LTV calculation. A block 50%+ vacant may attract a slightly lower LTV to reflect the income risk, but is still routinely fundable through the right lender on our panel.
How is a MUFB valued for bridging purposes?
Three methodologies are used depending on the block. Investment method (yield-based): used for fully-tenanted blocks, applying a market yield to gross annual rent. Vacant possession value: the sum of individual unit values, used for vacant blocks intended for sales. Gross development value: used for blocks under conversion or refurbishment, valuing the post-works finished block. Most blocks use a blended approach, particularly where part-tenanted.
What is the exit route from MUFB bridging finance?
Three exits are accepted. (1) MUFB commercial mortgage refinance - the most common, particularly for stabilised income-producing blocks. (2) Block sale to another investor - accepted where there is sales-process evidence. (3) Unit-by-unit sales - the block is bridged, units are sold individually, and the bridge is repaid from sale proceeds. Doulton models the most cost-effective exit at the outset and engages exit lenders in parallel with the bridge.
Can I use bridging finance to convert a commercial building to a MUFB?
Yes. Commercial-to-MUFB conversion is one of the highest-growth MUFB bridging use cases, particularly under permitted development rights (Class MA / Class O). Bridging can fund the commercial acquisition while planning or prior approval is confirmed, then a development facility (or works tranche on the bridge) funds the conversion. Final exit onto MUFB commercial mortgage or individual unit sales completes the project. We arrange the full structure end-to-end.
