Selling a block of flats: the two values, who buys, and how to present one
The same specialism that kept competition down when you bought a block keeps it down when you sell. That is a manageable fact if you plan for it and an unpleasant surprise if you do not. Here is how a block sale actually works, from an owner who buys them.
The short answer. Decide which of the block's two values you are selling: the investment value of the whole building on one title, or the sum of what the flats would fetch individually after a title split. That decision picks your buyer, your route and your timetable. Then present the block the way a buyer and their lender need to see it: a verified rent roll, a complete compliance pack and clean title. Most blocks sell whole, to another investor, on the income. Some are worth splitting first. A few are best sold at auction. None sell well with paperwork missing.
Start with the two values, because they pick the buyer
The idea at the centre of the owner's guide to MUFBs matters most on the day you sell. A block has an investment value, judged on its rent roll and the yield an investor would accept, and a sum-of-the-parts value, what the flats would be worth sold one by one to ordinary buyers with ordinary mortgages. The gap between them is often substantial and it is specific to the building and the area.
Selling the whole block on one title means selling the first number, to a small pool of buyers, quickly. Selling the second number means creating a lease and a title for each flat first, then selling to a large pool of buyers, slowly, with legal costs and a tax event on every sale. Neither is automatically right. A block in an area where individual flats sell poorly, or an owner who needs the money this year, is often better off selling whole. A block in an area with strong demand for flats, held by an owner with time, may be leaving a great deal on the table by not splitting. Nobody should take that figure from a website: it is a conversation with a valuer who knows the patch, on the specific building, and how a valuer decides what split flats are worth explains what they will look at.
Who actually buys blocks
Almost everything a block owner needs to know about selling follows from the buyer pool being thin and specialist.
- Portfolio investors buying income. They price on yield, they want tenants in place, and their lender will only lend against the rent roll as it stands. They are the natural buyer for a block that runs well.
- Title splitters buying the gap. They can pay more than a pure yield buyer because they intend to realise the sum-of-the-parts value, but less than the retail figure, because the split costs money and time and they carry the risk. They look hard at whether the split is actually possible.
- Developers where there is planning upside: a roof extension, a conversion of a commercial part, more units. They price on the finished scheme less the cost and the risk of getting there.
- Company buyers who take the shares of the company that holds the block rather than the building. More due diligence, different tax on both sides, and a route worth knowing about if the block sits in its own company.
- Owner-occupiers, who only arrive once each flat has its own lease and title, and who are the reason the sum-of-the-parts value exists.
Blocks often trade off market, between people who know each other, because the buyers are few and they are known. A direct buyer who understands blocks can complete faster than a listing that waits for the right investor to notice it, which is the whole case for We Buy Blocks, the buying brand in this family of sites, and it is stated plainly on the about page.
The four ways to sell
| Route | Who buys | The trade-off |
|---|---|---|
| Sell the whole block on one title | Investors, title splitters, developers | Fastest and simplest. Priced on the income. Fewer buyers than a flat has. |
| Sell the company that owns it | Experienced company buyers | The buyer takes the history with the shares, so more due diligence and warranties. Different tax treatment on both sides: accountant first. |
| Title split, then sell the flats | Owner-occupiers and small landlords, one flat at a time | Realises more of the sum-of-the-parts value. Slow, costs legal fees and a tax event per sale, and you can keep some and sell some. |
| Auction | Whoever is in the room | Certainty and a fixed completion date, at the price the room pays. The route for a block with a problem nothing else will transact, rarely the first choice. |
The company route is explained in buying the company instead of the block on The Title Split Consultant, written from the buyer's side, which is exactly the side you need to understand as a seller. The split route is a project in its own right: the steps are in the title split process, step by step and the bill in how much a title split costs.
How an investor prices your block
On the income, and on the income as it is. An investor takes the current rent roll, applies the yield they and their lender will accept for that kind of building in that area, and arrives at a number. The finish of the kitchens does not rescue a yield that does not work, and the rent the flats could achieve is your upside, not theirs, until it is in the tenancy agreements. A lender who spoke at our deal clinic described a block whose rents had never been raised: worth far more if it were let at market rent, but only purchasable at a much lower price, because a lender will not lend beyond what the current rent supports. If you have time before you sell, the single most valuable preparation on an under-rented block is bringing the rents to market, lawfully and with proper notice, so the number the buyer sees is the real one.
Arrears, a tenant on old terms, or missing compliance paperwork all reduce the price or kill the sale, because they are the buyer's lender's problems before they are the buyer's.
The pack that makes a buyer say yes quickly
A block buyer is deciding with their lender and their solicitor at the same time, and the pack is what lets all three move. Put it together before the block is marketed, not after the first offer.
- Title. The register and the title plan, with the common parts, gardens, bin stores and parking clearly shown. Any restrictions, charges or rights of way explained.
- Income. The rent roll, unit by unit, with every tenancy agreement, deposit protection certificate and proof of rent received. Any arrears disclosed, not discovered.
- Compliance. The fire risk assessment of the common parts and evidence the actions were done, gas safety records, electrical reports, an energy performance certificate for every flat, any licence the council requires, and an asbestos survey where the building needs one. The freeholder's duties guide sets out the full list.
- Insurance. The current buildings insurance schedule and the rebuild cost it is based on, covered in insuring a block of flats.
- The building. Floor plans, how the utilities are supplied and metered, planning and building regulations history for any conversion, and the works history with invoices.
- Running costs. What the common parts cost to run each year: cleaning, lighting, maintenance, insurance, management. A buyer is pricing the net, not the gross.
Every document you leave out costs you money, because a buyer prices uncertainty into the offer and a lender prices it into the loan. The solicitor who spoke at our deal clinic made the mirror point from the buyer's side: poor seller compliance is one of the commonest reasons a block deal stalls, and asking for the paperwork early tells a buyer why a block has been hard to sell.
Selling with tenants, selling from a company, and tax
An investor wants the tenants in place, because the tenants are the product. Make sure the tenancies are properly documented, the deposits protected, the right to rent checks on file and the rent arriving where the bank statements say it does. If the block is held in a company, decide with your accountant whether to sell the building or the shares before you go to market: the two routes attract different taxes and different buyers, and changing your mind after an offer is expensive. Whichever route you take, the sale is a tax event, and the time to understand what you will keep is before you accept an offer, not after. Confirm all of it with your accountant on your own facts.
Timing
A whole-block sale to a cash or bridge-funded investor can complete in weeks; one to a mortgaged investor follows their lender's timetable; a split-then-sell programme runs over months or years. If you need the money by a date, say so early, because speed is something a direct buyer can offer and an open-market listing cannot promise. If you do not, the question is whether the sum-of-the-parts value is worth the wait, and that is the one question on this page that has a different answer for every block.
Common questions
Who buys blocks of flats?
Mostly other investors: portfolio landlords buying income, title splitters buying the gap between the block price and the sum of the flats, developers where there is planning upside, and company buyers who take the shares of the company that owns the block. Owner-occupiers only enter the picture once flats have their own leases. It is a thin pool compared with the market for a single flat, which is why blocks trade at a discount and why a direct buyer can be the quickest route.
Do I have to title split a block before I sell it?
No. Many blocks are sold whole, on one freehold title, to another investor. Splitting first can realise more of the sum-of-the-parts value but it takes time, costs money, and is a taxable event unit by unit. Whether it is worth doing is arithmetic specific to the building, and sometimes the honest answer is sell whole.
Is it better to sell a block with tenants in place or empty?
To an investor, tenanted, because they are buying the income and an empty block has none. A buyer wants to see the rent roll evidenced, the tenancies in order and no arrears. Vacant possession only helps if the buyer plans to refurbish, convert or sell the flats individually, and that buyer will price the void period in.
Can I sell the company that owns the block instead of the block?
Yes, if the block is held in its own company. The buyer takes the shares and with them the company's history, so expect more due diligence and warranties. The tax treatment on both sides is different from a sale of the building, in ways that need an accountant's advice on your own facts before you choose the route.
What paperwork does a block buyer ask for?
The title and plan with the common parts marked, the rent roll with every tenancy agreement and proof of rent, the compliance pack (fire risk assessment, gas and electrical certificates, an energy performance certificate per flat, any licences), the buildings insurance schedule, how the utilities are supplied, the running costs of the common parts, planning and building regulations history, and the works history. A missing document costs more than it saves.
