Buying a Freehold Block of Flats with a Split-Valuation Bridge

A split-valuation bridge lets you buy a freehold block of flats at the block price, fund it against the higher split (leasehold) value, then refinance the flats onto individual buy-to-let mortgages with minimal money left in. A freehold block is valued at a discount to the sum of its parts, usually 10% to 15%. The strategy is built to capture that gap. FD Commercial arranges the bridge, the title split and the buy-to-let refinances from £250,000 across England, Scotland and Wales.

What is a split-valuation bridge on a freehold block of flats?

A split-valuation bridge is short-term finance used to buy a freehold block of flats where the lender sizes the facility against the aggregate of the individual leasehold flat values rather than the lower freehold block value. That difference is the whole point.

Freehold blocks held on a single title are valued at a discount to the sum of their parts, typically 10% to 15% and sometimes wider on larger buildings. A valuer applies the discount because one buyer is acquiring the entire block in a single transaction. Split the same building into individual long leasehold titles and each flat can be valued, mortgaged and sold on its own at the higher individual figure. The gap between the block value and the aggregate split value is the value this strategy is designed to capture, on top of any below-market discount you negotiate on the purchase itself.

In most of the deals we arrange, the borrower buys the freehold block at the block price, draws a bridge sized against the split valuation at completion, grants individual long leases to split the title, then refinances each flat onto a separate buy-to-let mortgage. The aggregate buy-to-let lending repays the bridge and returns most or all of the original deposit. The flats end up individually titled and individually mortgaged, and the cash comes back out to fund the next deal.

Why does a freehold block sell for less than the sum of the flats?

Because a block buyer and a flat buyer are not the same buyer. A freehold block on one title is an investment lot bought by a landlord or investor in a single deal. A leasehold flat is a home or a single buy-to-let bought by an individual. The pool of buyers for the block is smaller, the lot size is larger, and the valuer reflects that with a block discount, usually 10% to 15% below the aggregate of the individual leasehold values.

The discount is real and it is recognised across the market. What it also means is that the freehold block carries trapped value. Split the title and the discount unwinds. That is the inefficiency the strategy exploits, and it is why the right block at the right price can be one of the most capital-efficient ways to build a buy-to-let portfolio.

What we have seen over the last few years is more investors buying freehold blocks specifically to split them, rather than to hold as a block. The maths is better and the exit options are wider. You can hold every flat, sell some and hold the rest, or sell the lot on individually for the aggregate value.

How does valuing on the split figure mean minimal money in?

Two effects stack on top of each other.

First, you buy at the block price, which is already below the aggregate of the individual flats. Second, a lender willing to size the facility against the split valuation lends against the higher figure, so the day-one advance covers more of the purchase price and your deposit is smaller. Then, once the title is split, each flat is refinanced onto a separate buy-to-let mortgage at its individual leasehold value. The aggregate new lending repays the bridge and returns your cash.

Put plainly: you are buying the cheap version of the asset and borrowing against the expensive version. Most lenders will not do this. They value the freehold block on the block basis and apply the discount, which means a bigger deposit and a longer wait. A smaller group of specialist lenders will lend against the split valuation at completion, and some will accept a day-one remortgage rather than holding you to the six-month rule. That lender appetite is the difference between the strategy working on minimal cash and the deal needing a full block-basis deposit.

Block valuation or split valuation: what is the difference?

A block valuation, sometimes called a multi-unit freehold block or MUFB valuation, values the whole building on one title as a single investment asset. It is usually assessed on a bricks-and-mortar or investment yield basis and it carries the block discount. One title, one loan, one valuation figure.

A split-title valuation values each flat as an individual long leasehold unit and adds the figures together. That aggregate is typically 10% to 15% higher than the block figure. It is the basis on which ordinary buy-to-let lenders prefer to lend, because they are lending against a flat they could repossess and sell on its own.

If you are keeping the building as a block on one title and one mortgage, a multi-unit freehold block mortgage is the product, and our guide to block versus aggregate valuation covers how the two bases are assessed. The split-valuation strategy is the opposite move: you deliberately break the block into individual leasehold titles to access the higher valuation and the wider lender market.

Which lenders will value on the split basis, and on day one?

A small group of specialist bridging lenders and a handful of commercial and buy-to-let lenders will value a block on the split or leasehold basis where the valuer supports the individual figures and the leases are being created as part of the transaction. Mainstream lenders will not. They value the freehold block on the block basis and apply the discount, which is the right call for them and the wrong outcome for this strategy.

Two lender policies decide whether the deal runs cleanly.

The six-month rule. Most mainstream buy-to-let lenders will not remortgage a property until it has been owned for six months, a policy drawn from UK Finance guidance and adopted as internal policy across the market. On a split block the clock generally runs from the date each new lease starts. The structure handles this in one of two ways: use a bridge to hold the position until mainstream lenders will refinance, or use lenders that accept a day-one remortgage and will lend against the new leasehold value immediately.

The over-exposure rule. Most buy-to-let lenders will lend on no more than 25% to 35% of the flats in a single block, so they are not over-concentrated in one building. A six-flat block therefore usually needs two or three buy-to-let lenders across it, or a limited company portfolio facility structured to sit within each lender's exposure limit. This is routine, but it has to be planned before the bridge is drawn, not discovered at the refinance.

This is where full access to market earns its keep. The bridge lender, the valuer's basis, and the refinance lenders all have to line up at the start. Get one wrong and the cash-out shrinks.

How does splitting the title on a block of flats work?

Title splitting creates an individual long leasehold title for each flat, granted out of the freehold. It is a legal process, handled by a conveyancing solicitor, and it usually completes within a few weeks of the bridge drawing.

In a typical structure the freehold is held by one entity, the borrower personally or a freehold company, and long leases are granted to a buy-to-let holding company for each flat. The leases are commonly 999 years at a peppercorn or nominal ground rent. They are registered at HM Land Registry, which creates separate leasehold titles that can each be mortgaged independently.

Lenders care a great deal about the lease terms. A long lease at a peppercorn ground rent is clean and mortgageable. A short lease, or one with an escalating or onerous ground rent, is difficult to mortgage and difficult to sell, which kills the buy-to-let exit. The Leasehold and Freehold Reform Act 2024 has reshaped the ground rent and lease extension landscape, and the direction of travel is firmly towards low or peppercorn ground rents. Granting your new leases on those terms keeps every flat financeable.

One point your conveyancer and accountant must cover early: granting leases between connected entities at a premium can trigger Stamp Duty Land Tax. It is not always due and it is not always large, but it has to be modelled into the deal rather than discovered after completion.

How much does it cost to split the title on a block of flats?

The cost of splitting is modest against the uplift, but it must be budgeted. The table below sets out the typical components on a small block. Figures are indicative and depend on the solicitor, the number of flats and the complexity of the existing title.

On a six-flat block the legal and registration cost of splitting is usually in the region of £8,000 to £15,000. Set against an uplift that can run to tens or hundreds of thousands of pounds across a block, that is a cost worth paying. The number that matters is not the splitting cost. It is the cash you get back at refinance.

What rates, LTVs and terms apply to a block-of-flats bridge in 2026?

The bridge on a split-valuation block is priced like any other unregulated investment bridge, against the security, the borrower and the exit. The table sets out indicative 2026 terms. The Bank of England base rate has held at 3.75% since December 2025, with the next decision due 18 June 2026, and bridging rates have settled accordingly.

Interest is normally rolled up or retained to exit rather than serviced monthly, because the flats are not yet let and generating rent during the splitting and refinancing window. That means the net day-one advance is lower than the headline facility once retained interest and fees come out, which is a number to model carefully when you are working out how much cash you actually need to complete.

Worked example: a six-flat freehold block bought below the split value

The figures are illustrative and every block is different, but the shape is the shape of the deals we arrange. Buy at the block price. Borrow against the split value. Split the title. Refinance the flats. Take the cash back out.

What are the risks, and what can go wrong?

This is a strong strategy, but it is not a guaranteed cash-out, and we would rather you went in with the downside in full view.

The valuation. This is the one that matters most. If the valuer reports a block figure rather than individual leasehold values, the higher advance disappears and the deal collapses to an ordinary block purchase needing a full deposit. The deal lives or dies on the valuation. Confirm the basis before you exchange.

The six-month rule. If you are relying on a mainstream buy-to-let lender to refinance and they hold you to six months from the date the new lease started, your bridge runs longer and costs more. Plan the refinance lenders, and whether they accept day-one remortgages, before you draw.

The over-exposure rule. A block usually cannot be refinanced with one lender. Two or three lenders across the block adds time and coordination. On a larger block this is a project to manage, not an afterthought.

Lease terms and ground rent. Onerous ground rent or short leases make flats unmortgageable. Grant long leases at peppercorn ground rent, in line with the direction set by the Leasehold and Freehold Reform Act 2024, and the flats stay financeable.

Stamp Duty Land Tax. Granting leases between connected entities at a premium can trigger SDLT. Model it with your accountant before completion, not after.

The bridge running on. Rolled-up interest compounds. If the split and refinance slip, the cost eats into the gain. A clean, planned exit is the whole game.

How do you arrange a split-valuation block bridge?

The process below is how we run one of these at FD Commercial. A clean case completes in 2 to 6 weeks to the bridge drawdown, then a few weeks for the split and the refinance.

1. Confirm the valuation basis before exchange. Get it in writing that the valuer will report individual leasehold values, not a block figure. The whole strategy depends on it.
2. Structure the ownership. Decide how the freehold and the leases are held, with the conveyancer and accountant advising on connected-party SDLT and lease terms.
3. Arrange the bridge against the split value. Indicative terms within 48 to 72 hours, sized against the split valuation where a lender will support it.
4. Complete and split the title. Complete the purchase on the bridge, grant the individual long leases, register the new leasehold titles at HM Land Registry.
5. Refinance onto buy-to-let mortgages. Each flat onto a buy-to-let mortgage at its individual value, spread across two or three lenders or held on a limited company portfolio facility, using day-one remortgage lenders where needed.
6. Repay the bridge and release the cash. The aggregate buy-to-let lending clears the bridge and returns your deposit. The flats are individually titled and mortgaged, the cash is out, and the next deal is funded.

Top 10 things to know about split-valuation block deals in 2026

1. The gap is the deal. Freehold blocks are valued 10% to 15% below the aggregate of the individual flats. The strategy captures that gap.
2. You buy the cheap version and borrow against the expensive version. That is what produces the minimal money in.
3. The valuation basis is everything. A split valuation makes the deal. A block valuation breaks it.
4. Only a short list of lenders will value on the split basis at completion. Most value the block and apply the discount.
5. The six-month rule decides your refinance route. Either bridge for six months or use day-one remortgage lenders.
6. The over-exposure rule spreads the refinance. A six-flat block usually needs two or three buy-to-let lenders.
7. Grant long leases at peppercorn ground rent. Onerous ground rent or short leases make flats unmortgageable.
8. Budget the splitting cost. Usually £8,000 to £15,000 on a six-flat block, modest against the uplift.
9. Take SDLT advice on connected-party lease grants. It is case specific and must be modelled in advance.
10. Plan the exit before you draw the bridge. The whole structure depends on a clean, planned refinance.
